Body Composition

Sports Nutritionist and Athletes' performance

How does the athlete’s body composition impact their performance?

By BIA, Body Composition, Fitness, Muscle, Nutrition

When most people think of nutritionists, they think of “healthy eating” and weight loss. However, the importance of sports nutritionist to maximise the athlete performance is fundamentally linked to diet and body composition too.

See Min, a professional sports nutritionist who works at the National Sports Institute Malaysia, recently joined the Malaysian contingent to the Southeast Asian Games in Hanoi to support the national team, shared her experience with how she accurately tracks athletes’ body composition using Bbioelectrical Impedance Analysis (BIA).

How does the BIA application provide a better strategy to maximise athletes’ performance?

Bioelectrical impedance analysis, as See Min mentioned, is one of the convenient methods for monitoring body composition in the sports nutrition field. It is utilised to monitor segmental lean mass for sports in a mass group, such as team sports, especially when regular assessment is required at different training phases. This is highly useful when sports nutritionists want to monitor changes in athletes’ body composition as the sports seasons change and adjust the dietary plan to assist athletes in achieving body composition goals that allow for maximum performance during competition.

By referring to the result sheet printed out from the BIA devices, sports nutritionists are able to explain body composition changes to athletes and coaches with ease. This allows the athletes to understand how their dietary practice and training programme could affect their body composition and performance in competition.

Can women gain the same relative amount of muscle mass as men?

By Body Composition, Body Composition Analysis, Fitness, Health, Muscle

If you’re like most women, you’re curious about whether doing the same routine as the men in your CrossFit class will give you the same results. On average, baseline muscle mass in men is 36% greater than in women. In terms of muscle distribution, women tend to have less upper body muscle mass compared to men.

Men have a slight genetic advantage over women because of their higher baseline muscle mass, particularly in the upper body. However, that doesn’t mean that women will gain less muscle mass than men, despite lifting the same amount of weights.

When men and women exercise for the same amount of time, they can accomplish the same amount of gains in muscle mass. While the increase in size was similar between men and women in the study, the relative strength of women actually increased more than men because they were starting with a smaller overall body size.

In addition, it’s worth noting that muscle mass gain may be more affected by individual variations in terms of sensitivity of resistance training responses rather than gender differences.

Does Weightlifting Causes Women To “Look Bulky” ?

What This Means For Women:
It’s possible to gain as much muscle mass as men, but it may take more work on your end because of your slightly lower baseline muscle mass. However, if you’re worried about getting too big, it’s also unlikely to happen due to differences in testosterone (we’ll cover that later,) and how you train.

The first step toward achieving enough amount of muscle mass is to do a body composition analysis to determine how much you have. Click here to read more about the various types of BIA devices that analyse body composition.

Does Weightlifting Causes Women To “Look Bulky” ?

By Body Composition, Body Composition Analysis, Health, Muscle

Many women believe that resistance exercise causes weight gain and a “bulky appearance”. Yes, strength training can lead to weight gain. You can almost certainly count on that. That is, nonetheless, totally acceptable.

If the gains you’re seeing are in Lean Body Mass, your weight may stay the same or even rise, but you’ll appear more lean and toned.

Understanding How Muscle is Gained

To begin, let’s be clear about how muscle is gained. Muscle growth occurs when the rate of muscle protein synthesis exceeds the rate of muscle protein breakdown.

In other words, you can only gain muscle through a process in which resistance training breaks down muscle fibers and then repairs them with enough nutrients from diet and rest. As a result, the muscles will grow in size, resulting in [muscle hypertrophy](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6950543/#:~:text=Muscle hypertrophy occurs when muscle,muscle protein breakdown [8].).

It is important to note, however, that muscle hypertrophy occurs at different rates for different people. Building “bulky” muscles take time and effort, and it is not a common result able to be achieved through weightlifting for the majority of women.

Women’s Muscle and Hormone

Women and men muscle difference

It’s understandable that seeing selfies of men in the gym with massive muscles while scrolling through social media can be frightening. And you might worry that working out in the gym will only lead to a bulky appearance.

Contrary to popular belief, women do not have the same level of testosterone as men, which is the primary hormone responsible for muscle hypertrophy. In general, women’s bodies only contain 10% to 20% as much testosterone as men’s bodies. As a result, women are much less likely to gain significant muscle mass from weightlifting.

Have You Eaten and Lifted Enough?

You might have to eat more calories than you needed to in order to appear “bulky.” This is due to the fact that gaining muscle requires a calorie surplus.

Several studies have shown that women tend to have low-calorie diets and, worse, low protein intake. This dietary habit was strongly linked to sarcopenia or progressive muscle loss. Instead of being concerned about gaining too much muscle, the problem of muscle loss should be prioritized among women.

Aside from that, muscle building requires progressive overload in weightlifting. This is because muscle gain will adapt to the same weight carried during your exercise routine. To achieve greater muscle gain, you must gradually increase the weight lifted.

The Benefits of Weightlifting for Women

Not only does weightlifting not lead to significant increases in muscle size for women, but it also has numerous other benefits.

Weightlifting can improve bone density, which is particularly important for women as they are more prone to osteoporosis than men. It can also improve balance, coordination, and flexibility.

In addition, weightlifting can boost metabolism and help you burn fat. This is because muscle tissue burns more calories than fat tissue, even when you’re not exercising. As a result, incorporating weightlifting into your fitness routine can help you achieve your weight loss goals.

Think of weight training as an investment that pays serious dividends down the road. The more muscle you have, the more visceral fat in your body can burn over time.

How to Safely Incorporate Weightlifting into Your Fitness Routine

Before starting a weightlifting routine, it is important to consult with a certified fitness professional. They could guide you with proper form and technique, which are also crucial to avoiding injury and getting the most out of your workouts.

It is also important to gradually increase weight and intensity and to incorporate rest and recovery time into your routine. This will keep you in good condition and allow you to perform weightlifting exercises safely.

The Importance of Tracking Progress

One of the keys to success in any fitness or nutrition journey is tracking your progress. This is where a body composition analyzer like the InBody machine can be incredibly useful.

Summary

To summarise, weightlifting is a safe and effective form of exercise that will not make you “look bulky” in the majority of cases. Weightlifting is a valuable addition to your fitness routine because of its numerous benefits, including increased bone density, metabolism, physical strength, and mental health.

By incorporating weightlifting into your exercise routine and dispelling the myth of “bulky muscles,” you can meet your fitness goals while also improving your overall health and well-being.

So, jump off your treadmill and give the free weights a try! By doing so, you’ll not only dispel this myth but also reap the numerous benefits that weightlifting has to offer.

Body Fat Percentage doesn’t always give a complete picture 

By Blog, Body Composition, Fat mass, Fitness, Muscle

If you’re using body composition tools like calipers to measure your body fat percentage to assess your health, then you’re already ahead of most (like those who are still using BMI).

But be aware that body fat percentage doesn’t always paint a complete picture when it comes to body composition. What’s more, decreases in your body fat percentage don’t always mean fat loss.  That’s because body fat percentage is a simple equation of your fat mass divided by your total weight.

Percentage Body Fat = Body Fat Mass / Total Body Weight

In some ways, body fat percentage is the most basic of all body composition results, because it only requires your Fat, Fat-Free Mass (or Lean Body Mass), and total weight.

While fat and fat-free mass are enough to give you a body fat percentage value, it isn’t always enough to explain changes in body fat percentages or give enough information to determine whether your body fat levels are healthy. You will get much more context about what your body fat percentage means if you look at it alongside things like Skeletal Muscle Mass. These are the muscles in your body that you can grow and develop through exercise.

Without assessing your amount of Skeletal Muscle Mass, your body composition assessments are going to be incomplete.  You won’t be able to fully understand the changes in your body fat percentage, and you may also be misled by what your body fat percentage means.  Here are a few examples:

1. You’re working out, but body fat percentage doesn’t change (or increases)

This situation can occur when you are working out to gain muscle in order to improve your physique, but you aren’t seeing the changes in the mirror that you hoped to see as quickly as you’d like. When you check your body fat percentage, you don’t see any change despite a month of hard workouts. What’s going on?

The first thing to check is to see if your weight has changed. It probably has. If your weight has increased but your body fat percentage remains unchanged, this likely means that your SMM is increasing at the same time as your Fat Mass. As you increase musculature, fat gain can occur due to the caloric surpluses required to increase SMM. This is a well-recognized phenomenon and is commonly referred to in gym-speak as “bulking.”

 

Additionally, situations can occur in which after initial drops in body fat percentage, the percentage rises right back where it used to be after a couple months.  Why?

This is because your body has entered what is referred to as an anabolic state – the condition in which your body increases muscle production.  Your body will require more calories than what you’re used to in order to build more muscle than it had before.

Not all of these calories, however, are going toward muscle development.  Being in a calorie surplus can lead to fat gain as well, which can cause an increase in body fat percentage.

2. You’re Losing Weight, But Your Body Fat % Doesn’t Change (or increases)

Similar to #1, this situation also involves little or no change in body fat percentage but instead of occurring due to anabolism, this time, catabolism is the driving force behind the change.

In catabolism, the body is focused on reducing tissue, not building it.  In order to lose weight, especially fat, the body should be in a catabolic state; in order to be in a catabolic state, the body needs to be in a caloric deficit (taking in fewer calories than needed).  In gym speak, this is referred to as “cutting.”

If you observe that you’re losing weight, but you don’t see the results in the mirror that you’d like to see and notice that your body fat percentage is unchanged, this is because your SMM and Fat Mass are actually decreasing together.

 

Why would Skeletal Muscle Mass decrease when you’re trying to target body fat only?  Although there isn’t a singular cause, the majority of the time this is caused by improper training and diet.

Most weight loss is a combination of body fat and skeletal muscle.  That much is unavoidable. For this reason, preserving or even increasing muscle becomes a priority when encouraging the body to enter a catabolic state.  This means ensuring your nutrient intake is balanced while engaging in some kind of resistance or weight training.

Many people neglect these important precautions and cause their body to metabolize muscle as well as fat.  Depending on how much muscle is lost, body fat percentages can drop extremely slowly, stay the same, or in extreme circumstances, increase.

3. Your Body Fat Percentage is Acceptable, But You’re Underweight

At first, this doesn’t seem like it makes sense – how can you be at a healthy body fat percentage, but not be healthy overall?  Simple: you’re underweight.

Underweight individuals may have enviable body fat percentages which can lead some people into believing that they are healthier than they actually are. However, if you are underweight, this means that you don’t have enough muscle mass.  Being underweight doesn’t get as much popular attention as being overweight does, but over time, being underweight can lead to the development of osteoporosis, which is diagnosed when a person has low bone density.

Not having enough muscle mass will also become problematic if you get sick.  When you become sick, the body’s need for amino acids to power its immune and recovery processes increases, and it will look to your muscle mass for those amino acids.  Essentially, your body will start to break down muscle in order to fight and recover from disease, and if you’re underweight with a healthy body fat percentage, you won’t have enough muscle to easily fight off illness.

4. Your Body Fat Percentage is Acceptable, But You Have Muscle Imbalances

Even if you are at a healthy weight and have an acceptable body fat percentage, only having Fat and Fat-Free Mass as results can hide potential issues. Because Fat-Free Mass is a catchall term for everything in your body that isn’t attributed to fat, an absolute value for Fat-Free Mass can’t describe how well developed this mass is in terms of your overall body composition.  In order to see that, you would need to take a closer look at how this mass is distributed segmentally.

Specifically, people can have well developed Lean Body Mass areas in some parts of their bodies but not in others.  Some people prefer developing upper body muscle while neglecting lower body muscle development. Others may have what’s referred to as a bilateral imbalance, which occurs when one side of the body is stronger than the other.  Here’s what that looks like from a body composition analysis viewpoint:

In this example, this person has almost one pound of muscle difference between their right and left arm.  Although this might seem more of an aesthetic problem, significant muscle imbalances such as the one shown above can also contribute towards injury.  Shoulder muscle imbalances in volleyball players, for example, have been shown to increase the onset of shoulder pain and injury.

It’s Just One Number

Although your body fat percentage is a very significant and useful number, relying on any one number, even an important number like body fat percentage, will never provide you with a complete picture about your overall health.  While body fat percentage is a very good way to assess your weight, it only takes Body Fat (and by extension Fat-Free) Mass and Weight into account.

In order to maintain your weight and understand the changes that your body experiences over time, including your change in body fat percentage, you will need more specific values than just Fat and Fat-Free Mass.  If you don’t compare your body fat percentage to Skeletal Muscle Mass, you won’t be able to:

  • Understand increases and decreases in body fat percentage
  • Maintain a healthy body fat percentage in respect to a healthy weight and muscle mass level
  • Determine if your muscles are balanced

Your body is a very complex system of many components all working together. That is why it is very important to get as much information as possible in order to understand your weight and your health properly. Calipers are a good a start, but in order to assess whether you have a healthy body composition try devices like a DSM-BIA device, that will go beyond body fat percentage and give you your muscle mass and body water results.

Cardio V.S Weights

Cardio vs Weights vs Concurrent: What’s better for body composition?

By Body Composition, Fitness, Muscle, Nutrition

Highlights

  • Aerobic Exercise- the ultimate exercise for increasing heart health, vascular health, and metabolic rate.
  • Resistance Training- the best training for gaining muscle strength and function. 
  • Concurrent Training- get the best of both aerobic and resistance training. 

When you think of exercise, what immediately comes to mind?

Going out for a jog? Loading up weights at the squat rack? Or maybe both?

All of those classify as exercise, but they serve different purposes. If you want to increase your squat 1-repetition maximum by 50 pounds, a daily cycling class won’t get you there.

It’s clear that your body adapts differently to different types of exercise, but how does that happen and what does it mean for your health?

This article will break down the benefits of different fitness regimens: aerobic, resistance, and concurrent training. In the process of reading this article, you will soon discover that your fitness goals can be achieved with some basic exercise physiology background!

What is Aerobic Training?

Aerobic exercise stimulates the heart and breathing rate to provide your muscles with oxygenated blood. The energy that powers such exercise is produced in muscle cells primarily via an oxidative pathway, meaning oxygen is required.

That explains all the heavy breathing when you go out for a run, doesn’t it?

That oxygen is delivered via blood being pumped from your heart, through your arteries, and returning to the heart through your veins.

So, it’s apparent that aerobic exercise primarily works two systems: energy production in your muscle cells and blood delivery in your cardiovascular system.

So how does this help you?

Does Aerobic Training Strengthen The Heart?

Aerobic exercise trains the heart to be stronger and more efficient at circulating blood. With aerobic exercise, the chamber of the heart (left ventricle) that pumps blood to the rest of the body literally gets larger and squeezes out more blood per pump, which means its stroke volume is increased. This results in an improved capacity for cardiac output, which is the quantity of blood pumped by the heart per minute.

If you’ve heard of hypertrophic cardiomyopathy (enlarged heart), it may seem counterintuitive that a large left ventricle muscle is a beneficial adaptation to aerobic exercise. But, important characteristics differentiate an enlarged left ventricle due to healthy aerobic exercise training and one resulting from disease.

strong, efficient heart is exactly what you want in order to live a long and healthy life.

If your heart is bigger and stronger, pumping more blood per beat, it doesn’t have to beat as rapidly. That’s why you often hear of elite endurance athletes with resting heart rates in the 30’s and 40’s. This is more important than it may seem: lower resting heart rate is associated with reduced risk of cardiovascular disease.

All these cardiac adaptations are aided by an increase in blood volume that occurs with aerobic exercise training. Without getting too technical, the expanded blood volume improves the heart’s contractility and filling capacity, allowing it to pump more blood per beat.

Although the heart is a different type of muscle than what’s in your arms or legs, it’s still subject to a related function. It contracts in order to move blood throughout the body. In addition to making it stronger and more efficient, you can also lighten the heart’s load by decreasing the resistance it faces.

How does aerobic training reduce arterial stiffness?

Each time the heart beats, arteries in the body provide resistance to the blood flowing.

The resistance provided by arteries is variable, though. Aerobic exercise training reduces the heart’s workload by reducing arterial stiffness.

When you perform aerobic exercise, your heart rate increases, pushing more blood through your arteries than at rest. The inner wall of your arteries feel the increased blood flow, and through a series of mechanisms, causes your arteries to widen.

As you train and your arteries experience this regularly, they become more effective at expanding. If you don’t regularly do aerobic exercise, your arteries never experience this stretch and they literally stiffen up (it is harder for your heart to pump blood through a stiff tube). Additionally, arterial stiffness is associated with coronary artery plaque development, the stuff that causes heart attacks.

Aerobic exercise also impacts your vascular system by promoting capillary growth. Capillaries are the microscopic vessels where oxygen diffuses from red blood cells to muscle (and other) cells.

Aerobic exercise requires increased oxygen delivery to the muscle to produce energy, so your body grows more capillaries to be able to better handle the energy demand.

How does aerobic exercise affect your metabolism?

Along with cardiovascular adaptation, aerobic exercise substantially impacts your muscles’ energy production system. Once blood delivers oxygen to the muscle cells, they still have to use it to produce energy that powers all the exercise you’re doing.

Aerobic exercise also relies to a great extent on breaking down fat molecules for energy, which can only happen within mitochondria.

Consequently, aerobic exercise training drastically improves your muscle cells’ ability to burn fat by generating more mitochondria and improving their functionality.

High-intensity aerobic exercise also increases your excess post-exercise oxygen consumption (EPOC), resulting in increased calorie burn after training sessions in addition to what you burned while exercising.  However, to maintain EPOC as you gain fitness, make sure to gradually progress your training intensity.

How Does Aerobic Training Impact Body Composition?

People who struggle with being overweight or obese have likely been told that aerobic exercise is a cornerstone of any weight loss routine.

The key to aerobic exercise is that it keeps the heart rate elevated for a continuous amount of time. While this will help to burn calories, it has specific impacts on body composition that people should keep in mind.

study published by the American Physiological Society took a look at the effects of regular exercise in adults. This study lasted eight months and placed adults on either aerobic training programs, resistance training programs, or a combined program. The researchers found that those in the aerobic training program lost more weight overall, including more fat mass than those in the resistance training program. On the other hand, those in the resistance training program gained more fat-free mass, including lean muscle.

To recap, aerobic training causes the cardiorespiratory system to adapt. It maintains heart function and health and keeps your energy metabolism system running.

Aerobic exercise is a jackpot for fitness and a key element of maintaining your health. But it may not get you big muscles or make your body much stronger…what will?

What Is Resistance Training?

 

Resistance exercise is training that progressively overloads your muscles. Some examples of resistance training would be traditional weightlifting, bodyweight exercises like pushups and pullups, and resistance band exercises. These types of exercises are meant to make your muscles bigger, stronger, more powerful, and more functional.

Specific adaptations to resistance training begin within the muscle cells. However, you’ll still get systemic benefits ranging from muscle growth to cardiovascular benefit.

To gain a deeper understanding of the whole-body performance and health effects of resistance training, read into how resistance exercise affects muscle at the microscopic level.

How does muscle adaptation work?

The point of resistance training is to make muscles function more effectively. This all starts with the contractile proteins that act to control muscle shortening and lengthening.

When you do resistance exercise, some of those proteins get yanked apart. That, along with the stress your muscle experienced, is the stimulus for your muscle to rebuild – this time bigger, stronger, or more powerful than before.

After resistance exercise, your muscle synthesizes proteins (this is aided by nutritional stimuli i.e. protein consumption). Special cells known as satellite cells also spring into action to help build up the broken down muscle. They normally lie quietly adjacent to muscle cells, but resistance exercise tells them to get to work.

Satellite cells combine with the muscle cells that were strained and damaged during your resistance training session. In doing so, they lend their molecular machinery to support protein synthesis that leads to muscle hypertrophy.

Resistance training with loads over 60% of your 1-repetition maximum results in hypertrophy of primarily type II fibers (‘fast-twitch’). These fibers are capable of rapid contraction with high force but tire more easily.

These micro-level adaptations matter to athletes and the general population alike. When you make measurable gains in muscle mass, strength, or power, you can thank the protein synthesis and fiber-specific adaptations that occurred within your muscle cells.

How does muscle hypertrophy occur? 

All those microscopic adaptations add up to cause changes that are easier to grasp. Resistance training at the proper intensity leads to measurable muscle hypertrophy. Strength improves in part due to changes to the neuromuscular system. Control over your muscles is typically a balance between competing neural signals. Some of those signals tell the muscle to contract, while others prevent contraction.

Regular resistance training can reduce neural inhibition that normally limits the strength and/or endurance of the muscle.

Muscle accounts for roughly 20% of resting energy expenditure, so it impacts on calorie burn and body composition is meaningful. Not only that, but you can’t increase the mass of most of the other organs that account for resting energy expenditure, like the liver, heart, brain, and kidney. Muscle is different because it hypertrophies, growing larger, and expending more calories.

By packing on muscle, not only do you increase strength, power, and function, but you also raise your basal metabolic rate. And by doing so, you’ll see an increase in your metabolism and an improvement in your health.

Does Weight Lifting Count as Cardio? 

If you’ve ever lifted weights or done resistance exercise, you’ve probably felt your heart pounding with the exertion.

Does that mean you’re getting cardiovascular and metabolic adaptations like you would with aerobic training?

Maybe not.

Resistance exercise does raise your energy expenditure. But it does so differently, and to a lesser extent, than aerobic exercise.

Resistance exercise trains your energy production systems but has less impact on the aerobic energy systems.

Is Resistance Training For Everyone?

Even if you’re not an athlete. Resistance training is important for functional fitness.

Functional strength training is defined as: “Training that attempts to mimic the specific physiological demands of real-life activities.” Unlike more traditional strength training (which focuses on specific muscle groups during each exercise), functional training focuses on whole muscle groups to train the body for daily demands.

A common misconception is that you may be too old for resistance training. But clinical data from a multitude of sources clearly shows the benefits of improving one’s functional fitness level, particularly for older adults.

Functional training such as resistance exercises and bodyweight movements can help you become stronger, more flexible, agiler and better equipped to handle day-to-day feats of strength and athleticism that are often overlooked. Plus, it can help you become less injury-prone.

study recruited seniors who were struggling with their physical abilities and placed them in a resistance-training exercise program. At the end, the researchers observed an increase in their fat-free mass, their muscle mass, their gait speed, and their overall physical capacity. This shows that resistance training not only improved body composition in the elderly but also helped to increase mobility to improve their ability to complete day to day activities.

How Does Resistance Training Impact Body Composition?

study found that regardless of the frequency of the resistance training program, participants increased overall muscle strength. The participants increased lean body composition.

Resistance training is a great way to increase lean muscle mass, and it improves the physical capacity of the elderly, leading to significant improvements in their quality of life. This evidence supports the positive capabilities resistance training has in both building lean body mass as well as maintaining lean mass in aging populations who are at risk of muscle loss.

These adaptations to resistance exercise impact your health and physical performance. Your muscles carry you through the day and increase performance if you’re an athlete.

Breaking down and building up muscle through resistance training is essential to maintaining function as you age. Loss of muscle mass even threatens some people’s capacity to live independently.

In terms of body composition, muscle mass is not only an important component to maintain, but it also contributes to your resting metabolism, helping you maintain a healthy energy balance.

Resistance training benefits the cardiovascular system, but its role is mainly for muscle gain and function.

But, how can you reap the benefits of both aerobic and resistance training? Do you just combine the two however you want?

What is Concurrent Training?

Concurrent training is the combination of both aerobic and resistance exercises within the same training session. Aerobic and resistance exercise impacts your body differently, so it follows that they each cause adaptations via different mechanisms.

How should I order my aerobic and resistance workouts?

In practice, aerobic/interval and resistance training don’t seem to interfere with each others’ adaptations all that much. But, understanding a few specifics about concurrent training will allow you to make good decisions about your exercise program.

The type of aerobic training determines how it interacts with resistance exercise adaptations. While strength and hypertrophy gains could be diminished by adding run training to a resistance program, cycling does not have the same effect.

Why? Researchers aren’t exactly sure. But it may have to do with two factors:

  • Cycling ergonomics are more similar to traditional lower-body resistance exercises
  • Eccentric muscle contractions in running result in muscle damage, while the concentric contractions in cycling do not (to the same extent).

The modality of aerobic exercise (running versus cycling) is important to understanding the effect of concurrent training, but so are frequency and duration. In some cases the more aerobic training you add to your program, the more you may impact muscular adaptation. So pair your training programs correctly; a running program in conjunction with an upper-body lifting exercise may benefit overall, but a running/leg press workout every day could interfere with one another.

And if you’re doing both aerobic and resistance exercise in the same session at the gym, or even on the same day, you’ll want to consider the order in which you do the exercises. It’s basically a matter of prioritization.

If your priority is on building aerobic fitness and performing well in a running race, do your aerobic exercise first in a session, followed by resistance exercise.

On the other hand, if your priority is building strength and muscle, you’ll want to do resistance exercise followed by aerobic.

However, the order probably doesn’t matter if you’re untrained.

The takeaway: if you’re untrained and haven’t set distinct fitness goals yet, don’t worry yet about the order of aerobic or resistance training. Do both and start exercising your way to health!

How do you develop a Concurrent Training program that’s right for you? 

If you’re just going to the gym to stay healthy, the benefit of gaining both aerobic and muscular fitness is well worth it.

To get the most benefit from your hard work at the gym, make sure to use these tips:

  • If your priority is muscle strength and growth, choose aerobic exercise like cycling rather than running to complement your lifting routine.
  • Consume enough protein and carbohydrates to stimulate muscle growth and recovery after workouts
  • If you alternate aerobic and resistance sessions, maximize recovery time between sessions (separate them by at least 6 hours)

Chances are that concurrent training is right for you, so go get started!

A Well-Rounded Exercise Program

As people continue to struggle with obesity and functional fitness as they age, exercise is more important than ever. It is vital to combine diet and exercise to not only lose weight but have a favorable impact on body composition and your lifespan.

Furthermore, it is important to have a well-rounded exercise routine that touches on all types of fitness. Aerobic exercise is effective at maintaining an elevated heart rate and losing fat-free mass. On the other hand, resistance training helps to build lean muscle mass. You can combine the two, with concurrent training, or jump into an explosive HIIT workout when you don’t have much time or need a motivation boost.

With this insight, you will be better equipped to understand why exercise is important for your health (a great motivator), how different types of exercise interact, and which ones are best suited for your needs.

Can Knowing Your Somatotype Help You Change Your Body Composition?

By Body Composition, Fitness

Are you one of those people who exercises regularly, but can’t understand why you don’t look like that person next to you at the gym? Do you get frustrated that your friend seems to be able to eat just about anything and never looks like they gain an ounce? Or how about those lucky individuals who have an outstanding athletic physique without even trying.

We are often quick to attribute these differences to the mysteries of different body shapes or somatotypes but rarely go beyond the basic body classifications to explore how our body types differ. What we should instead focus on are factors we can control instead of our genetics. How about we instead study how each different body types responds to factors like diet and exercise, and how we can work with our body type to effectively change or optimize our body composition.

Let’s examine each different somatotypes, see how you can use an understanding of your genetic predisposition to make better decisions to reach your specific body composition goal.

The Three Somatotypes

A somatotype is defined as a “quantitative overall appraisal of the present shape and composition of the human body.” Classifying different body types based on physique provides three generalized divisions of body typesendomorph, mesomorph, and ectomorph. As with anything, it’s rare for someone to fall entirely into one somatotype. You might show a combination of qualities from two somatotypes, such as an ectomorph-endomorph hybrid or an endomorph-ectomorph.

There are countless articles about how having a general idea of where you fit on the somatotype scale can help give you the knowledge you need to make informed decisions in your quest to change your body composition. However, before we examine these claims more closely, let’s take a quick look at the general structures of the 3 somatotypes:

The Shapes

Ectomorphs

That super skinny friend of yours that often gets called a “stick” falls primarily into the somatotype category of an ectomorph. Naturally lean with a tendency towards long limbs, ectomorphs typically possess that slender look no matter what type of diet they consume. A lot of endurance runners and swimmers are ectomorphs. Although ectomorphs may have a decent amount of muscle, due to their long limb-length, they may appear visually to have less muscle development. Similarly, body fat also seems to get hidden by their long, slender figure – meaning ectomorphs seem to get away with a few extra pounds of fat. Because of this, if ectomorphs aren’t taking care of their health, they can become  skinny fat.

Mesomorphs

Mesomorphs are the natural athletes out of the three somatotypes. They are the lucky few, that can achieve a muscular physique without really trying. The physiology of a mesomorph tends to include narrow hips, wide back, and larger frame that contributes to an often muscular appearance. Many professional fighters, wide receivers, and basketball players fall are mesomorphs.

Endomorphs

Endomorphs are the larger structured somatotypes with both wide hips and shoulders but shorter arms and legs. This type of body shape is great for activities that require a lot of strength. When you think of endomorphs, think of rugby props, strength athletes, and powerlifters. Endomorph body-types are even considered to be a contributing factor in race performance in Ironman athletes.

The Composition

Recall the definition of somatotypes as having both a shape and composition component. While your shape may be set from the start, your body composition is not set in stone. So what are the general body compositions for these different somatotypes?

Ectomorphs look lean and often they do tend to get placed into the category of endurance athletes. People with these body types seem to struggle with gaining weight and altering their body composition through lean muscle mass gain. Their efforts in the gym may seem to have little effect visually, even causing frustration when trying to initiate a change.

Mesomorphs, on the other hand, have a larger frame that lends to the appearance of a body composition with a high percentage of lean muscle mass and a lower body fat percentage. The result is a more athletic, muscular look.

Endomorphs tend to have shorter, rounder frames, with the appearance of a large amount of both muscle and fat mass. However, due to their stockier features, body fat stored by these individuals tend to be more readily noticeable compared to the other body structures.

Now that we have a better idea of what these three somatotypes look like, let’s see what this really means for your body composition goals and whether or not you can make a difference despite your genetics.

Nature vs. Nurture

Considering somatotypes and body composition often leads to the question: Is our body type predetermined by our genetics or can you impact the way your body looks with my lifestyle choices? Numerous studies have investigated the hereditary implications of body composition and the effect of genetics versus environmental factors. Let’s take a look at what they’ve found.

We know that we inherit our genes from our parents. Studies do show a genetic connection between parents and children (nature)-– also reflected in similarities amongst siblings– with the maternal genes having a more significant impact in many cases.

So somatotype is hereditary, but external factors have an effect as well.

Lifestyle choices, like diet and exercise, both affect your overall body composition and can contribute to that slender or stocky look. There’s certainly a link between diet and body composition, where a diet (or lack thereof) can either promote or hinder your health goals. Similarly, your appearance will also greatly depend on the type of training you engage in and whether your goal is to build strength, size, or muscular endurance.

What does this tell us?

In a nutshell, while your body shape and size may be somewhat set in stone, your body composition is not.

Breaking Out of the Mold

It’s important to remember that somatotypes describe different body types in order to provide general guidelines for health and fitness. Remember, somatotypes are defined as a “quantitative overall appraisal of the present shape and composition of the human body.” While you may be genetically predisposed to have a certain body structure, your lifestyle can impact your body composition and cause your somatotype to change.

Let’s look at the example of the ectomorph. Ectomorphs have been implicated to be better at aerobic exercises like running or swimming. Intuitively, this makes sense. Having longer limbs helps increase stride length and a lower overall body fat percentage helps reduce resistance caused by excess body fat. Races have actually introduced the concept of “Clydesdale or Athena” runners since lower weight has been attributed to better running performance in marathons. Mesomorphs and endomorphs, on the other hand, may possess shorter limb length that may allow them to engage in more power and strength building activities, contributing to the image of these body types having greater musculature.

Now, let’s say an ectomorph wanted to become a powerlifter and achieve a larger figure, breaking out of his ectomorph shell.  Would he be condemned to the life of an ectomorph or can he still achieve one of the other body types?

Think about it this way: If an ectomorph ate cheeseburgers and milkshakes all day and lifted weights like a powerlifter, would he always look like an ectomorph or would his body shape eventually become more of a mesomorph type shape, or even an endomorph type shape?

The point is, just because you fall into a certain somatotype, doesn’t always mean you’re stuck in what your body type ‘should’ excel at. Take volleyball for example: a study looking at somatotype in elite volleyball players found that players in various positions had different somatotypes.

Furthermore, your somatotype doesn’t limit what you can do to change your body. A study conducted on weightlifters found that there were athletes from all body types scattered throughout the participants. So even if your genetics play a large role in predicting your body frame, you can still engage in the types of activities you enjoy to ensure your genetics don’t decide your overall body composition.

How Can This Information Help You Change Your Body Composition?

Genetics can prevent you from changing your body structure, but your shape doesn’t tell you what body composition you have to have. Knowing your somatotype can allow you to work with your body to make adjustments to factors you can control, rather than working against it and being constantly frustrated by your lack of success.

For example, many NBA athletes start their career with an ectomorphic frame due to their long torso and limb lengths in conjunction with their slender figure. With years of full-body strength training and conditioning, they shift their somatotype to a hybrid ectomorph-mesomorphic body type that makes them ideal bodies for the sport of basketball.

So remember, your body shape can change. Which brings up another important point – monitoring those changes in the long run. As a mesomorph, you may be happy to show off your naturally athletic-looking body at the pool, or as an ectomorph, you may enjoy the way dresses drape your long, slender frame.

But beware: like anyone else, you have to maintain a healthy body composition through healthy lifestyle choices. Despite your current body shape or health, you’re still at risk of sarcopenia (age-related muscle degradation) or fat accumulation due to unhealthy lifestyle choices like a poor diet or lack of physical activity.

Relying on the perks of your somatotype isn’t a long-term strategy for health and longevity. Continued resistance training, even simply once or twice a week at moderate intensity, can help prevent muscle loss related to aging and maintain an optimal body composition.

The More You Know

Understanding your somatotype can be helpful if you’re someone who has struggled to find a form of exercise that complements your physiology. You may be able to develop an exercise routine that feels more natural and easier to commit to if you consider your body structure. However, don’t let your current body structure impact your decision to do something you’re interested in, just because it’s not a perfect fit. While certain somatotypes may correlate with athleticism, there’s no specific gene that determines whether or not someone will become an elite athlete.

In conclusion, having a general idea of your somatotype and understanding your body structure can help you make the changes required to alter your body composition, However, the most effective way to achieve your body composition goals is still testing your body composition and tracking your changes.

There is no one-size-fits-all solution when it comes to body composition. We come in all shapes and sizes, and discovering what works best with your somatotype will help you take the necessary steps to achieve your body composition goals.

Your Body and You: A Guide to Body Water

By Body Composition

When it comes to your health, most of the focus is on body fat and muscle mass, which is important. But not to be overlooked is your body water. Water is a major part of your body: they make up 79% of your muscles , 73% of your brain, and even 31% of your bones. Overall your body weight can be 45-65% water.

Your body water percentage is influenced by your age, gender, and fitness level. Even though you are made up of mostly of water, how much do you really know about the effect this major element has on your body?

Body Water, Defined

Like discussed above, your body water can be found inside not only in your blood, but in your muscle tissue, your body fat, your organs, and inside every cell in your body.  To account for all this, your total body water (TBW) can be divided into two basic groups.

  • Extracellular Water (ECW)

Extracellular water is the water located outside your cells.  The water in your blood falls into this category. Roughly 1/3 of your fluid is attributed to ECW, and this water is found in your interstitial fluid, transcellular fluid, and blood plasma.

Extracellular water is important because it helps control the movement of electrolytes, allows oxygen delivery to the cells, and clears waste from metabolic processes.

  • Intracellular Water (ICW)

Intracellular water is the water located inside your cells.  It comprises 70% of the cytosol, which is a mix of water and other dissolved elements.  In healthy people, it makes up the other 2/3 of the water inside your body.

The intracellular water is the location of important cellular processes, and although it has many functions, a very important one is that it allows molecules to be transported to the different organelles inside the cell.  Essentially, the Intracellular water picks up where the Extracellular water left off by continuing the pathway for fuel to be transported to the cells.

Balance is the Key

When it comes to your body water and you, the most important thing to strive for is balance. Your Intracellular fluid:Extracellular fluid must remain at the same levels with respect to each other.

A healthy fluid distribution has been estimated at a 3:2 ratio of ICW:ECW. If your body water falls out of balance, this can signal changes in your health and body composition. Whether these changes are positive or negative depend on which type of water becomes unbalanced.

Increased  ICW

Having slightly more ICW than normal isn’t necessarily a bad thing. In fact, it can signal positive changes in your body composition. 

Increased muscle mass is due to the enlargement of the number and size of muscle cells.  When the muscle cells become enlarged, they are able to take in (and require) more ICW in order to power their cellular functions.  Research has shown that resistance exercise can lead to increased intracellular water in humans. Increased ICW as a result of exercise is a sign of increased Lean Body Mass, which is a very good thing and has positive health benefits, including:

  • Increased Energy Use

Your Basal Metabolic Rate (BMR) is the amount of calories you burn at rest.  It is the baseline for the calories you need every day in order for your body to operate and maintain daily functions.  With increased Lean Body Mass, your energy needs will increase as a result of a higher BMR. If you don’t increase your daily calorie intake, but increase your Lean Body Mass/BMR, you will create a calorie deficit – which can lead to body fat loss.

  • Increased Strength

Your Lean Body Mass is sometimes described as your fat free mass.  Your Lean Body Mass accounts for all your weight due to water, muscle mass, bone, and protein.  One of the easiest ways to influence the amount of Lean Body Mass you have is to increase your muscle mass.  Generally, increased muscle mass leads to increased strength.

  • Increased Immune System

Increased Lean Body Mass through exercise has been associated with increased immune system functionality.  This will help your body fight off illnesses more easily.

Excess ECW

If your ECW increases in relation to your ICW, this is something you should take special note of.  Unlike ICW, you do not want to see your ECW increasing beyond normal levels. Excess ECW can indicate health risks, including:

  • Inflammation

During inflammation, the body sends additional blood flow to the damaged area.  This causes an increase of extracellular water in a particular area. Inflammation occurs when part of the body gets damaged or bruised and is a normal bodily response to injury.  This is called acute inflammation, and is a temporary increase in ECW.

Chronic inflammation, however, is something more serious that isn’t always readily detected. It is marked by long-term swelling/ECW increases caused by cellular stress and dysfunction. Chronic inflammation can lead to serious diseases if allowed to persist over time, including renal failure, cancer, and heart disease. including renal failure, cancer, and heart disease.

  • Renal Disease (Kidney Failure)

One of the kidneys’ major functions is to filter your blood and remove toxins produce in the body.  One important substance that the kidneys filter out is sodium, an element that is found in salt.

When your diet includes more sodium than your kidneys can filter out, which occurs in people who have failing kidneys, your extracellular water levels will increase.  In some cases, this increased extracellular water shows in visible swelling throughout the body and is a condition known as edema. Edema can cause additional strain on the body by contributing to weight gain, blood pressure, and other complications.

  • Unhealthy Fat Mass Levels (Obesity)

Obese individuals are characterized by having too much body fat, which among other things, leads to body water disruption due to excess ECW.  This is because excess visceral fat can trigger production hormones that can lead to the disruption of a bodily system called RAAS.  This excess ECW causes stress in the body due to its effects on the internal organs, which can exacerbate obesity and cause a dangerous cyclic effect.

Determining Balance

Since it’s so important to keep an eye on your fluid balance, you’ll need to know how you can determine yours. There are two major methods to measure and determine your fluid levels.  These are the dilution method and the BIA method.

The dilution method involves drinking a known dose of heavy water (deuterium oxide) and allowing it to distribute around the body.  Once the water has had time to settle, the amount of heavy water is compared with the amount of normal water. The proportion will reflect the amount of total body water.  To determine ECW, sodium bromide is used instead of heavy water.

The dilution method is recognized as a gold standard for measuring total body water; however, these tests would need to be done at a hospital under the guidance of a trained physician.  This test takes several hours to complete during which any fluid of any type going in or out of the body has to be carefully recorded.

For these reasons, you’re unlikely to have this test performed unless your doctor needs to know your total body water with absolute certainty because of a serious health complication.

The second, more accessible method to determine body water content is bioelectrical impedance analysis (BIA).  For most people who do not have serious medical issues, this method is much more practical than the dilution method.

A small electrical current is applied to the body, and the opposition that current experiences (impedance), is measured.  From that impedance result, a BIA device can report your body water percentage. Advanced BIA devices are able to reflect the difference in Intracellular and Extracellular water as well, which can reveal the ICW:ECW balance.

Bringing Yourself Back Into Balance

Maintaining a balanced ratio of approximately 3:2 is ideal for optimal health.  If you find that this ratio is beginning to fall out of balance, there are some things you can do.  Fortunately, these tips aren’t anything you already haven’t heard before: maintaining a healthy diet, staying hydrated by drinking enough water, and exercising regularly.

Avoiding excess ECW is ideal.  From a dietary standpoint, one simple change that can work to reduce excess ECW is reducing the amount of sodium (salt) in your diet. Sodium is located primarily in your ECW, and when excess sodium is introduced into the body, the body’s natural response is to draw water out of your cells at the expense of your ICW.  Reducing your sodium intake has a number of positive health benefits, so this tip can be considered simply a best practice for optimal health in addition to being a tactic for reducing high ECW.

On the flip side, increasing your ICW can be achieved by increasing your Lean Body Mass/increasing muscle mass through exercising.  As the muscle cells increase in size, they will require more water to maintain their function. Exercise has the additional benefit of combating obesity, and as fat mass is reduced, ECW increases due to obesity will decline over time.

As you can see, body water can be an important indicator of your overall health.  Without a healthy ICW:ECW ratio your body will begin to have problems.

The best thing you can do for proper body water balance is to maintain a healthy lifestyle. If you can achieve a healthy lifestyle, your body water will fall into balance naturally.  The first step would be to find out where your body water levels are today, so you can start planning for a healthier life now.

 

How to Stop Overeating Once and For All

By Body Composition, Diet, Nutrition

At dinner last night, one slice of chocolate cake somehow turned into half a cake…

Today, you stuffed yourself with five buttery rolls at the office potluck. That wouldn’t have been so bad if you didn’t eat three plates of food.

We’ve all been there, and we all know how those post-binge episodes go — from guilt to frustration to promising yourself that it’s going to be the last time you stuff yourself with unhealthy food! (Not to mention the dreaded food coma…)

You thought you’ve overcome overeating for good, yet it turns out that you’re back to square one when it comes to getting your cravings under control.

Why is it so hard to break out of this cycle?

Is there a way to kick this ceaseless habit for good?

Does it have to do with self-control and having an endless supply of willpower?

Or is there some otherworldly, mystical force that you need to tap on in order to break free from binge-eating episodes?

To help us figure out if it’s sorcery or science, this article is divided into two parts.

First, you’ll learn about the possible reasons why it’s so tempting to finish a large box of pizza all by yourself. Second, you’ll discover how to put an end to compulsive overeating and finally take your body composition goals seriously.

With obesity affecting more than one-third of the U.S. adult population, getting out of the binge-diet cycle remains a puzzle to many.

To have a greater understanding as to how overeating happens, it makes sense to initially get a grasp of how our appetite, or the desire to eat, works.

Understanding Overeating

How Appetite Works

It’s worth noting that appetite is a tad different from hunger. Think of hunger as a need to eat while appetite is more like a desire to snack mindlessly even after you had lunch.

At a fundamental level, hunger and appetite are both influenced by a network of pathways involving the neuroendocrine system. Appetite regulation, satiety, and energy balance involve the following:

The smart folks over at ASAPscience simplified the science of hunger and cravings in a two-minute video below. It talks about the body’s hunger-regulation system and why we’re tempted to go for second helpings.

In essence, high-calorie foods rich in fat and sugar were extremely desirable to our hunter-gatherer ancestors for survival because they were scarce. However, this instinct for fatty and sugary meals still remain even though these types of food are now available 24/7.

Eventually, the continual intake of high-calorie fat and sugar-laden food overrides the human body’s natural hunger regulation system, leading to habitual overeating.

In a nutshell, the more you gorge on food laced with too much fat and sugar, the more likely that you’re going to get addicted to it.

On Homeostatic and Hedonic Hunger

portion control

Another way of understanding appetite is to look at it from the perspective of eating for two main reasons— as a response to hunger (homeostatic) and for pleasure (hedonic).

In a review of studies differentiating the two, the researchers described that homeostatic hunger is the result of the prolonged absence of energy intake or the food itself, while hedonic hunger is strongly influenced by the availability and palatability of food in your environment. Furthermore, a 2016 study found out that intense feelings of pleasure derived from palatable foods (hedonic hunger) predicts the likelihood of losing control when eating among female college freshmen.

 

Why You Really Overeat and Binge

indulgence in ice cream

At first thought, it seems like putting an end to overeating is simply a matter of telling your brain to stop consuming food. Yet we all know that it’s not that easy, right?

Your brain may be the main driving force behind your cravings, but it’s not acting alone.

The frequency and the amount of food you finish is also influenced by a complex interaction of the following factors:

1. Genetic Influences

Your gut, hormones, and brain may be working together to control appetite, but your genetic makeup also has a say as if you’re the type to overindulge.

For instance, a London study on children revealed that genetic influences on weight and abdominal fat accumulation are high in children who are born since the onset of the childhood obesity epidemic. Furthermore, there is evidence indicating that specific genes can possibly impact your likelihood of frequent LOC (loss of control) eating episodes.

2. Environmental Influences

Environmental factors also contribute to the rise of food cravings. These factors include the atmosphere of the room and the presence/absence of distractions during meals. This also applies to social and cultural cues. Remember a time when you overindulged because everyone seems to be in the mood for feasting?

Finally, child feeding practices by parents during the first years of childhood tend to impact one’s eating behavior later in life. A review of studies on the parental influence on eating behavior revealed the following interesting findings:

  • Restrictive feeding practices by caregivers are associated with overeating and poorer self-regulation of food intake among preschool-age children.
  • Restricting access to palatable snacks and desserts like cookies in children may be counterproductive because it will eventually promote their intake.
  • Higher levels of parental control and pressure to eat healthily were associated with lower fruit and vegetable intakes and higher intake of dietary fat among young girls.

3. Psychological Influences

Did you know that not sleeping enough or getting stressed over finals week could lead to you reaching out for the cookie jar 5x a day when we’re not actually hungry?

It turns out that your appetite and hunger regulation is also influenced by these behavioral factors.

In fact, evidence from longitudinal studies suggests that chronic life stress may be linked to weight gain, with a greater effect seen in men.  Furthermore, your work schedule can also impact how much you eat. A study revealed that shift workers may be particularly vulnerable to the tendency to eat the largest meals in the evening as they remain awake longer during the times when you naturally feel hungry for high calorie sweet, salty, and starchy foods.

 

Your Action Plan to Curb Overeating (Without Depriving Yourself)

Whether it’s stress or social pressure that’s driving you to overeat, we all know how frustrating it is to realize that you gave in to your cravings (again!). The good news is you can do something the next time you’re about to open your third bag of chips.

For a start, consider the following easy yet sustainable solutions to put an end to overeating, minus the horrible feeling of self-deprivation.

1. Learn to recognize the difference between homeostatic and hedonistic hunger.

As mentioned earlier, you can eat because you’re hungry but you can also eat for pleasure.

It can be a struggle to figure out the difference between the two because it requires you to be more mindful and listen to your body. As a result, misinterpreting these signals can lead to overeating.

While these cues will differ from one person to another (as well as depend on the time of day), you can learn to recognize your motivation for eating and adjust your eating habits by asking the following question:

Am I eating as a response to a physical cue (e.g. growling stomach, headache) or am I eating because I am feeling stressed, anxious, or overjoyed?

Whether you’re stressed about deadlines or bummed about your annual employee performance review, talking to a friend or journaling may be more helpful than emotional eating.

2. Be mindful of your “food environment”.

food environment

Your “food environment” may be divided into two parts:

  1. Your social interaction and the overall atmosphere of your environment
  2. How your food is served

To help promote a positive food environment, consider the following best practices:

  • Keep an eye on your portions.

Before eating two bagels in one sitting, savor one piece instead. Furthermore, you might also want to use smaller plates and bowls to avoid taking in too much when you’re in a buffet. Research reveals that larger plates can make a serving of food appear smaller, and smaller plates can lead people to misjudge the same serving size of food as being significantly larger.

  • Press pause (whether on your TV or phone) until you’re done with lunch or dinner.

When you’re distracted, you tend to eat mindlessly. As a result, you’ll be less sensitive to satiety cues because your brain is paying more attention to other things.

  • Be like the Okinawans in Japan by only eating until your 80 percent full.

Known for having one of the longest life expectancies in the world,  Okinawans call this practice as “Hara Hachi Bu”, and this can be a useful guideline to help stop overeating.

  • Eat slowly.

A Greek study found that eating at a slower pace tended to increased fullness and reduce hungry feelings in overweight and obese participants.

Surround yourself with people who are taking steps to eat more mindfully.

Whether it’s your co-worker who’s into calorie counting or your brother who’s a geek when it comes to meal planning, being around others who eat mindfully will help reinforce your own good habits and perhaps teach you some new tips and tricks as well.

3. Make tiny adjustments to your daily habits that may impact your eating behavior.

Curbing overeating is not about making massive changes in your life but rather making tiny adjustments to your daily habits.

Going on a “healthy” detox diet or juice cleanse right after binging may help your weight loss temporarily, but it’s not sustainable in the long run. Instead, you’ll likely end up going through the same cycle of overeating, feeling guilty, restricting yourself, and giving in again to cravings. That’s why making smaller healthy changes is more effective for changing your lifestyle permanently.

These are three examples of tiny adjustments you can make to your daily habits.

  • Stop skimping on sleep, pronto.

As mentioned earlier, lack of sleep can lead to eating more and sabotage your weight loss efforts. Are you struggling to get a good night’s sleep? Establishing a consistent bedtime routine may be a good start. An irregular bedtime schedule is linked to poor sleep quality.

  • Eat breakfast when you can.

There may be some exceptions (like when you’re doing intermittent fasting), but skipping your morning meal usually leads to overeating because you end up feeling famished throughout the day. On the other hand, a healthy high protein breakfast has been shown to stabilize blood sugar levels, increased satiety, and reduced hunger cues.

  • Do whole food swaps instead of cutting out certain foods entirely or adopting crazy diets.

Remember how high-calorie food that’s loaded with salt and sugar tends to encourage overeating? That why food choices are important. By opting for whole food alternatives, you will eventually reduce your cravings for unhealthy sweets and salty treats.

Don’t just adopt the latest trending diet and toss all the junk food residing in your fridge right away. A good rule of thumb is to have at least 80 percent of your daily meals from whole food sources and devote the rest to the not-so-healthy food items. And when the craving hits reach for a healthy snack like fruit or nuts. By doing so, you won’t feel deprived, which in turn can lead to another binging episode.

Special Note on Food Addiction

A lot of people can relate to overeating (because it happens to the best of us too!) but food addiction is a different story. If you feel that your binging episodes has turned into more than just a bad habit that you can change, seek professional help.

The Takeaway: Mindful Eating Can Go a Long Way for Your Body Composition

mindfulness with food

If you’ve noticed, the majority of the points discussed in the action plan has something to do with mindfulness.

Recognizing if you’re truly hungry or simply eating as a response to stress or other environmental factors requires constant practice and a heightened sense of self-awareness.

The idea of mindfulness may sound like a meditation fad or just another self-help woo-woo. However, mindfulness-based interventions in addressing compulsive overeating and other obesity-related eating behaviors have gained popularity recently. In fact, a systematic review of related studies on the topic supports its efficacy.

Overall, beating overeating and taking your body composition seriously begins with this single step—uncover the reason behind your binging habit. Keep in mind that you need to know the “why” first before diving into the “how” of putting an end to your tendency to overeat. Once you figure out your “why” the benefits are tremendous: a healthier relationship with food, weight loss, and a better sense of control. Good luck and here’s to a happier more mindful life.

Are Abs Really Made in the Kitchen?

By Body Composition, Nutrition

There’s an oft-used saying that “abs are made in the kitchen.

The underlying theory, for those who haven’t heard this before, is that what you eat is more important than how much you exercise if you want to see defined abdominal muscles.

How much truth is there to this mantra? Are Instagram perfect abs really made simply by watching what you eat? Or can you just do a thousand crunches a day and reveal your six-pack that way?

In this article, we’ll 1) break down the science of nutrition vs. exercise and how each impacts body composition, 2) look at a few different types of diet plans and their effects on the body, 3) decide whether the saying “abs are made in the kitchen” is fact or fiction.

Let’s jump right in.

Background

The notion of “abs are made in the kitchen” is based on the fact that it is so much easier to gain calories than it is to burn it off through exercise.

 

This makes sense when you attach some numbers to it.

For example, let’s say your preferred exercise routine is swimming a few days a week. On average, you can expect to burn 400-700 calories in an hour.

But if you go home and scarf down a couple pieces of pizza, you can quickly take in the same amount of calories in a matter of minutes.

So from a time/practicality standpoint, it’s much easier to reduce your caloric intake by 400 – 600 calories a day and create the same calorie deficit as swimming/running for an hour.

However, this doesn’t necessarily mean that creating a calorie deficit through diet has the same effects on body composition as exercise.

First, we’ll look at some studies that weigh in (pun intended) on exercise.

How Exercise Impacts Body Composition

In a 2011 study published in the International Journal of Obesity, 320 post-menopausal women ranging in weight from normal to obese were split into two groups. The first were asked to do 45 minutes worth of moderate-to-vigorous aerobic exercise, 5 times a week for a full year (they actually ended up averaging about 3.6 days per week). The second group did not exercise. And neither group was asked to improve nutrition or try portion control.

After one year, the exercise group lost an average of 5.3 pounds of body fat.

That’s a lot of work to lose 5 pounds of fat.

HIIT, or high-intensity interval training, may be a more efficient approach to improving your body composition, especially in the abdominal region. One study compared two groups who exercised at different intensities: one that did three days a week of high-intensity exercise and another that did five days a week of low-intensity exercise. After 16 weeks, the high-intensity exercise group lost both more abdominal visceral and subcutaneous fat than the steady-state exercise one.

So it appears exercise, specifically high-intensity exercise, can produce faster results if you want to see those abs.

Next, let’s see what type of impact diet has.

How Diet Affects Body Composition

There are many different diet plans for those hoping to lose fat and/or increase lean body mass. We’ll look at some of the most popular and review which are effective for changing body composition and which need to be studied more.

Paleo Diet

The Paleo diet (or “Paleo” for short), consists of eating foods that are assumed to have been available to humans prior to the establishment of modern agriculture. If the caveman didn’t eat it, it’s out. This includes eating things like lean meat, fish, vegetables, fruits, eggs, and nuts. It excludes foods like grains, legumes, dairy, sugar, and processed oils.

Paleo is relatively new (in terms of nutrition research) and therefore doesn’t have a whole lot of credible evidence on its impact on body composition specifically. One meta-analysis published in the American Journal of Clinical Nutrition compared the Paleo to 4 control diets based on U.S. nutrition guidelines.

The researchers found that the Paleo led to greater short-term improvements in waist circumference, triglyceride levels, and blood pressure.

It’ll interesting to see if Paleo proves to be more effective than other diet plans on improving body composition as more studies become available.

Ketogenic Diet

The ketogenic diet (or “Keto” ) consists of eating high fat, moderate protein, and very low carb foods. It’s similar to Paleo but carbs are restricted to 25-50 grams per day.

A 2013 meta-analysis that compared Keto to a low-fat nutritional plan suggests that keto is more effective for weight loss as well as improvement of cardiometabolic health.

Another study that compared the ketogenic diet to a low-fat diet found that Keto was effective in short-term body weight and fat loss. On top of that, it appears that Keto may support preferential fat loss in the trunk area, although this requires further validation.

Finally, a study in which men performed resistance training three times a week and compared body composition effects of keto vs. the traditional Western diet found that the ketogenic group experienced significant fat mass loss, as well as lean body mass gains, compared to the Western diet group.

Mediterranean Diet

The Mediterranean diet is based on typical foods and recipes of Mediterranean-style cooking (native to Italy, Greece, Spain, etc.).

This includes large quantities of fresh fruits and veggies, nuts, fish and olive oil. The Mediterranean diet is one of the most studied diets and for good reason: It has been shown to help reduce the risk of heart disease, certain cancers, diabetes, Parkinson’s and Alzheimer’s diseases.

Let’s see what type of impact, if any, it has on body composition though.

One study on 248 healthy women published in the European Journal of Clinical Nutrition found that the Mediterranean diet could help reduce body fat levels.

Another study in subjects with coronary artery disease showed that adherence to the Mediterranean diet significantly reduced body fat mass and percent body fat.

A meta-analysis published in the journal Metabolic Syndrome and Related Disorders concluded that the Mediterranean diet “may be a useful tool to reduce body weight, especially when the Mediterranean diet is energy-restricted, associated with physical activity, and more than 6 months in length.”

Finally, when researchers looked at the Mediterranean diet’s effects on weight loss and cardiovascular risk factor levels in overweight or obese individuals trying to lose weight and compared them to low-fat diets, they found that the Mediterranean diet produced greater weight loss.

Diets: The Bottom Line

Science shows there’s no one-size-fits-all approach to dieting. A meta-analysis published in the Journal of the American Medical Association, reviewed 59 studies with various nutritional recommendations (low-fat, low-carb, etc).

Researchers found that weight loss differences between individual diets were small. Participants were able to change their body composition (lose weight) with both low carb and low-fat diets.

However, getting the right amount of protein seems to be one of the most important things you can do to improve your body composition.

In another meta-analysis of 87 studies published in the American Journal of Clinical Nutrition, researchers found that low-carbohydrate, high-protein diets favorably affect body mass and composition.

So it seems the consensus is that eating more protein can also help you preserve lean body mass when dieting.

Now, let’s look at the most effective approach for getting a six pack: combining a high protein/low carb diet with different types of exercise like cardio and strength training. This is where things get interesting.

How Exercise Combined with Diet Impacts Body Composition

According to another study published in the journal Obesity that compared the effect of dieting and exercising (alone or combined) on weight and body composition in overweight-to-obese post-menopausal women, the diet-only group achieved more weight loss than the exercise-only group. However, the greatest effects were seen in the combined diet/exercise group, “where 60% of participants achieved ≥10% weight loss at 1 year.”

Other studies show similar results: a combination of dieting and exercising works best if you want to lose fat (which is how you will see your abdominal muscles).

The question is, are certain types of exercise (resistance training, long duration cardio, etc) more effective than others for improving your body composition?

In a 2015 review published in the Journal of Diabetes and Metabolic Disorders, researchers analyzed 66 clinical studies and came to the following conclusions:

  1. Exercise in combination with diet led to the most significant changes in body composition.
  2. The combination of resistance training and diet was more effective than endurance training or a combination of endurance and resistance training at altering body composition measures (reduction of body mass and fat mass).

Conclusion

Making adjustments to how you eat can lead to more fat loss in less time compared to exercise alone.

So, the verdict? Abs are made in the kitchen and the gym.

Like anything worth achieving in life, getting a six-pack takes both work and knowledge. Doing 1000 crunches and 1 hour of cardio a day won’t help you see your abdominal muscles any faster if you don’t make the right changes to your diet.

“Spot reduction” is also another myth. You can target your abs and core with resistance training that help with the muscles in that area, but you also need to lose overall body fat to see the definition in those abdominal muscles– and that requires a combination of diet and exercise.

So where do you go from here?

First, determine your body composition goals. If your goal is to lose fat and gain more definition, then you’re going to have to eat at a calorie deficit. If your goal is to increase lean body mass and lose fat, then your diet and exercise regimen may look different.

At the end of the day, the best exercise/nutritional plan is the one you can stick with. Once you find the right approach for you, you can make it a lifelong habit. That’s what will give you your six-pack.

How to Use HIIT to Improve Your Body Composition

By Body Composition, Fitness

If you’ve been trying to get in shape recently and you’ve been scouring the Internet for effective workout styles, chances are you’ve stumbled upon something called HIIT, which stands for high-intensity interval training.

Over the years, professional athletes and fitness buffs alike have sworn by this training method.

Whether it’s lowering fat mass or increasing muscle gain, you’re probably wondering if it’s the right workout type that will help you attain your body composition goals as quickly as possible.

Read on below for a closer look of this popular workout style and how you can use it to effectively attain your desired body composition outcomes.

The Lowdown on HIIT

High intensity interval training (HIIT) is based on the premise that short, explosive burst of activities can have a huge, lasting impact on your body composition. In a nutshell, it’s not about how long you’re exercising but rather how intense you’re performing the workouts within a certain period of time.

In a typical HIIT routine, you alternate between intervals of quick, intense bursts of exercise and short, sometimes low intensity, periods of rest. Here’s how the American Council on Exercise (ACE) describes HIIT:

Most endurance workouts, such as walking, running, or stair-climbing —are performed at a moderate intensity, or an exertion level of 5-6 on a scale of 0-10. High-intensity intervals, on the other hand, are done at an exertion level of 7 or higher, and are typically sustained for 30 seconds to 3 minutes, although they can be as short as 8-10 seconds or as long as 5 minutes; the higher the intensity, the shorter the speed interval. Recovery intervals are equal to or longer than the speed intervals.

Running HIIT-style involves intervals of 30 to 60 seconds of running near your peak of ability. You follow this almost breathless (but definitely not winded) running with a comparable cool-down period of walking. For instance, you can do a short sprint upstairs and walk back down four times in a row.

While there’s no specific set of guidelines as to how often you should do HIIT,  alternating periods of high-intensity and low-intensity activities at least three times a week as part of your exercise routine is a good rule of thumb to reap its benefits. One study in the European Journal of Endocrinology reported that male subjects following an 8-week HIIT program experienced muscle gain and lost a significant amount of abdominal fat mass, even though the program included no weightlifting.

The great thing about HIIT is you can apply interval training to almost any type of workout — from interval running to doing explosive laps at the pool to your twice-a-week kettlebell routine. This means that you can continuously mix things up in your routine so you won’t get bored and give up on our body composition goals.

HIIT and Its Impact on Body Fat

Let’s look at HIIT’s impact on body fat.

HIIT has been shown to be effective in torching body fat more than other types of exercise. In terms of belly fat, studies found that HIIT workouts help reduce both visceral (fat mass around the organs) and subcutaneous (under the skin) fat.

Another study compared the results between a group of participants who committed to three days a week of high-intensity exercise routine and another group who did five days a week of low-intensity exercise. After sixteen weeks, the researchers discovered that the participants who committed to high-intensity exercise routine for three days a week lost more fat than the group who showed up for low-intensity steady-state exercise.

HIIT’s significant role in reducing fat mass is good news if you’re not seeing consistent results in reducing your body fat percentage (particularly that stubborn belly fat) despite your regular workout routine.

HIIT and Its Impact on Muscle Mass

As for HIIT’s possible role in building lean muscle mass, let’s take a look at the findings of a study published last year in the Journal of Diabetes Research.

The researchers compared the effects of five weeks of high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT) among overweight and obese, young women in terms of cardiorespiratory fitness, body composition, and blood glucose.

Participants in the HIIT group performed 60 repetitions of high-intensity interval exercise — at 8 seconds of cycling at 90% of peak oxygen consumption, and 12-second rest on a cycle ergometer for 20 minutes. Meanwhile, participants in the MICT group performed continuous cycling exercise at 65% of peak oxygen consumption for 40 minutes.

In terms of lean mass changes, the researchers concluded the following:

“..the MICT group experienced significantly decreased total lean mass (TLM) and leg LM. Meanwhile, TLM and leg LM in the HIIT group were unchanged. ”

Based on the study’s findings, here’s what we know so far:

  • HIIT may not be the most effective workout routine to build lean muscle mass
  • HIIT, however, can help preserve or retain lean muscle mass, while MICT can potentially make you lose lean muscle mass if you’re trying to lose fat mass at the same time

One of the many benefits of HIIT is that it increase the proportion of fast-twitch muscle fibers over slow-twitch muscle fibers.

Why is this important? Fast twitch fibers are a main factor of your strength and speed. They are also very important to train in that if you don’t use them, you lose them, especially as you get older. That being said, you can see how important muscle gain is when you are young, in order to maintain your strength and speed (reflexes) as you age.

While HIIT may not be as effective in increasing muscle mass, it does offer potential benefits to achieve that sculpted look.  However, if your main goal is to build muscle mass, bodybuilding or weight training may be your best bet. Here’s an in-depth look between bodybuilding and HIIT to improve body composition. You can note also that both these methods may be used in conjunction to help you to attain your desired body composition.

Additional Benefits of HIIT

Besides helping improve your body composition through fat mass loss, HIIT also provides the following benefits:

  • Short yet explosive bursts of exercise may be more effective in boosting your V02 max— a measure of aerobic endurance— than performing the same exercise at a slower pace. This can help you to use oxygen more efficiently and increase exercise performance.
  • Incorporating HIIT workouts into your exercise routine is more time-efficient. This study reveals that you get the same cardiovascular effects from traditional endurance training in HIIT in just a couple minutes.
  • New research findings published last April concluded that HIIT improves glucose metabolism in muscles and boosts insulin sensitivity among type 2 diabetics.
  • HIIT is perceived as a more enjoyable activity than moderate-intensity continuous exercise. This finding suggests that HIIT will likely promote long-term exercise adherence than other workout styles.
  • In a 2015 study comparing the afterburn effect, also known as excess post-exercise oxygen consumption or EPOC, HIIT (as well as weight training) reigns supreme over regular cardio up to 21 hours post-workout. The more oxygen your body requires to return to its resting metabolic state, the more calories you burn. This means that HIIT can help you burn more calories even after a day (or almost) you exercised.

Making the Most of Your HIIT Workout

To help you accomplish and maintain body composition success, there are various types of HIIT methods to choose from — from the Tabata protocol to turbulence training. Plus, HIIT can be applied to almost every workout routine or fitness setup out there. You can do CrossFit, engage in bodyweight workouts, or even do HIIT with Pilates.

Regardless of the workout routine or HIIT method you prefer, you can make the most of your HIIT routine by sticking to the following best practices:

  • Don’t forget to do some warm-up before you engage in explosive, high-intensity moves.
  • Aim for at least three-to-five minute intervals completed at least six times. This interval has been shown to provide long-term sustainable results in a systematic review of studies on HIIT protocols that are most effective.
  • Complement your HIIT routine with other workout styles or training programs such as yoga or trail running to keep things interesting.
  • Incorporate as many muscle groups as you can. Using more muscle groups will help to burn more calories!
  • Use your own body’s cues to gauge exertion level. For example, you’re doing it right if you can say single words in the middle of your HIIT routine but you should not be able to complete whole sentences. So if you still find yourself chatting it up at the gym in between reps and you’re not seeing results, maybe it’s high time to pump up the effort level a few notches.
  • Watch what and how much you eat. The best HIIT routine in the world will amount to nothing in the long run if you’re not mindful of your diet and nutritional needs.
  • If you have existing health issues,  it’s best to consult with your doctor or healthcare professional first before engaging in HIIT.

It’s All About Consistency

To benefit the most from any form of HIIT, build a habit of doing it consistently. Even if you can only spare a few minutes, you can effortlessly incorporate these quick interval workouts to your day.

How about getting off your social media of choice for about half an hour to do HIIT? Perhaps you can do reps with your officemates during lunch hour.

The next time you feel like exercise is a chore or a task that you need to check off your to-do list, introduce HIIT into your workout routine! You might not know it but a quick, fun HIIT sesh may be the missing piece in bidding adieu (finally!) to your current body composition woes.
