A Pound of Muscle Vs. A Pound of Fat: The Truth about Weight Loss
Most people have been around long enough to hear the concept that muscle weighs more than fat. Many people work out frequently as a means to lose weight, and they get frustrated by the fact the scale doesn’t go down, or the weight doesn’t drop fast enough. Sometimes, people work out every single day and find out that they are can’t lose the weight, or even gain a little weight, and they don’t understand why.
In the gym, you’ll hear the phrase muscle weighs more than fat frequently, and many people don’t fully grasp the underlying concept that this is trying to get across. The most important difference between muscle and fat as it pertains to weight loss is that muscle fits more mass into a smaller volume than fat. One pound of fat takes up around 18% more volume than a pound of muscle.
Losing Body Fat Doesn’t Necessarily Mean Losing Weight
This is one of the reasons why people that have trouble losing weight while exercising frequently get frustrated, but it doesn’t have to be that way. Because exercise builds muscle mass, especially anaerobic exercise, the combination of exercise and healthy eating can lead to a significant loss of body fat without majorly affecting the overall mass of the individual. After a couple of months of dieting and working out, you may only lose ten pounds or so, but the changes in body composition are much more apparent than the minor loss in weight (not to say that ten pounds isn’t an accomplishment in and of itself!
Body Mass Index is the basic rule of thumb when it comes to fitness by age and weight, but many people misunderstand the concept and consider it the be-all-end-all when it comes to gauging health. Because muscle weighs more than fat, the stronger that you are and the more muscle mass that you have, the less accurate that the BMI will be at assessing your health based upon your weight. BMI is very much based on the average specimen, and you want to be more than simply average, don’t you?
When you stick to a diet and fitness regimen, its certainly important to pay attention to the number on the scale, but understand that it is only one factor in regard to your physical transformation, and other factors such as muscle mass, muscle tone, and body fat percentage are more revealing.
The following image is a cross section of your muscle tissue. Notice how densely packed the tissue is? This is why Muscle tissue carries so much mass in so little volume:
Now look at this cross section of an adipose fat cell. Fat cells take up a lot more space, and are less compact, as you can see:
Fat vs. Muscle: A Visual Representation
The next photo shows five pounds of fat compared directly with five pounds of muscle. It’s incredibly clear that muscle takes up a whole lot less space than fat. Even when counting for the compression underneath the skin, fat is going to take up much more space than muscle. Also, fat contributes to the rounding and lumpiness of men and women with too much body fat, because body fat is more amorphous than muscle, which causes the body to take on a more unappealing shape.
It’s also important to know that you can’t see all body fat. The body also builds fat internally, and your organs are separated by fat tissue. In addition to this, the body isn’t designed to carry body fat efficiently. Our ancestors rarely had the opportunity to build a lot of fat, simply due to their hunter-gatherer lifestyle and the fits of feast and famine that they would endure. Body fat was an evolutionary benefit because it could keep people alive longer when times were lean.
Today, however, we in the United States live in a period of veritable, undeniable plenty that our ancestors never had the chance to experience, and thus, never adapted to. This is why being overweight or obese is such a health hazard. On the other hand, as a whole, we have historically been far more fit in the past than we are now. In order to catch our prey and fend off predators and enemies, we naturally stayed strong and fit. Our early ancestors also tended to be much more nomadic, which means that they were used to walking long distances every day. Today, most people can make it through the day with very little physical activity, which causes us to be much weaker and less fit than our ancestors unless we actually take the time to work out, exercise, and build our muscles.
Benefits of Working Out and Building Muscle Mass
Our bodies are designed to function optimally when we build muscle mass and tone. The following are some benefits that both men and women can experience by working out:
A Stronger, Sturdier, Physical Frame, More Resistant to Injury
A More Fit and Attractive Physique
Improved Psychological Health
Enhanced Sense of Well-Being
Increased Mobility and Balance
Improves Athletic Performance
Enhanced Healing Due to Improved Metabolic Profile
Healthier Cholesterol and Insulin Levels
And these are just the obvious benefits!
Out of all these benefits, the two that are perhaps most important are your metabolism and your Insulin Sensitivity. Let’s talk about those a bit more in-depth.
Every pound of body fat that you have is the equivalent of 3,500 calories of stored energy. Now, there are two ways to get rid of this body fat. You can exercise and burn through those 3,500 calories, or you can eat a more conscientious diet, and reduce your calories by 3,500 over a period of time, such as a week. Of course, you can combine these two methods as well.
There are three ways that you get rid of stored fat. For example, the respiration process uses up about 86% of the body fat calories that you expend each day. You get rid of around 14% of your fat calories through the acts of urination and sweating.
Increasing your activity level through weight training and resistance training is a highly effective way to increase the rate at which your body burns calories. Although fat carries more volume than muscle, it doesn’t burn energy as quickly. This means that pound for pound, the more muscle that you have, the faster your body will burn calories than it will per pound of fat.
How Many Calories Does Muscle Burn vs. Body Fat?
Specifically, a pound of muscle mass will burn around six calories per day, whereas a pound of bodyfat will only burn around two calories per day.
Of course, its important to remember that the benefits of building muscle mass are far greater than just your weight and your ability to burn calories. Some health specialists, especially those on television, like to emphasize the ability of muscle mass to incinerate calories, but this is a bit of an overstatement.
In the End, The Calories Your Muscles Burn at Rest Are Only a Piece of the Weight Loss Puzzle
On the other hand, most responsible fitness specialists think that it is important that their clients understand that muscle is better than fat at burning ambient calories, but these benefits have their limits, and are often overstated by many times. No one should be building muscle mass just to lose weight, because there is a chance you’ll be disappointed, especially if you don’t combine you anaerobic exercise with cardiovascular exercise and a healthy and nutritious diet.
In fact, if you just engage in anaerobic exercise, this may influence you to eat more and actually gain body fat if you don’t make further efforts to lose weight. This is why you see so many weight lifters at the gym that are obviously strong, but with a layer of fat over their huge muscles.
In the end, losing weight and being healthy is a concerted effort, and it is true that your ambient metabolism is important, but it’s only one part of the process. Many people put too much stock in their muscles’ ability to burn body fat, which causes them to be lazy or inefficient in following other aspects of a good and healthy lifestyle. A lot of folks also use their workouts as an excuse to overindulge. The brain plays tricks on the mind in order to fulfill its urges, which can be amplified by your increased metabolism.
Don’t Overwork Yourself to Lose Weight
Of course, it’s no good to spend too much time obsessing over your fitness and nutrition regimen as well. Many people, in an effort to get healthy and lose weight, spend hours at the gym each day, exhausting themselves and overworking their bodies. In an effort to lose weight, they combine this exercise with severely restrictive diets which deny them the necessary calories and nutrients they need to get through the day. In the end, this approach and those like it are incredibly unhealthy, because they actually damage their bodies through their actions. Even worse, these people often lose their gains in the end when they lapse from their hardcore training and dieting, or they succumb to an injury and give up on their health regimen. They often gain all the weight back and more.
The end-goal of a healthy fitness regimen is to provide the body thorough anaerobic and aerobic stimulation without going overboard, and combining that exercise with a thoughtful and healthy diet. It’s all about being smart about how you do things.
When it comes to health, strong basal metabolism is an important aspect, but controlling insulin and glucose levels is even more important for maintaining health, and it doesn’t involve hours upon hours slaving away in the gym, but a conscientious exercise and diet regimen that promotes optimal cardiovascular health and hormone balance.
Maintaining healthy muscle mass and combining it with a good diet keeps hormone levels optimally balanced, creating homeostasis in which Human Growth Hormone, Testosterone (for both sexes), and Insulin Levels remain in optimal range. When Glucose Sensitivity gets out of whack, this rewires the body, causing it to build body fat more quickly and inhibit weight loss as well as the ability to maintain a health body composition.
How Does Exercise Regulate Glucose Metabolism, Improving Body Composition and Health?
In an article published in the Journal of Clinical Endocrinology and Metabolism in 2011, researchers presented data which showed that insulin sensitivity is largely correlated with a patient’s muscle mass. In fact, a ten percent increase in lean muscle mass led to an average eleven percent reduction in insulin resistance.
More Muscle Mass = Less Risk of Diabetes
This is the main reason that people with more muscle mass have a lower incidence of diabetes. When individuals have optimal insulin sensitivity, this means that the body responds swiftly to the influence of glucose in the body. Patients with poor glucose sensitivity are more prone to directly convert glucose in the blood stream into fat rather than converting it into immediately usable energy.
If the body is creating energy directly from blood sugar, this helps the body burn fat more effectively, and also improves overall, general hormone balance. By taking responsible steps in one’s diet and lifestyle, it is possible to rewire the body by encouraging enhanced insulin sensitivity, keeping the body lean, strong, and full of energy.
Of course, this reiterates the fact that the scale doesn’t really matter. Improving body composition is a process, and improving hormone balance takes time. By taking fitness and nutrition seriously and responsibly, you put your faith in the science behind your body, and it benefits you most to not think of numbers on the scale as goals, and you really don’t have to think about them at all.
Don’t Get Hypnotized by the Scale
People that focus too much on the scale get frustrated, because they often don’t feel that the effort they’ve put in at the gym and at the dinner table is leading to the appropriate results. Becoming hypnotized by the scale blinds them to the physical changes occurring within the body and numbs them to the psychological and metabolic benefits that they are likely experiencing. This is actually one of the primary reasons why people lapse from their regimen, but it doesn’t have to be that way!
Anyone that has ever made the effort to try to lose weight likely understands this plight, or even knows what it feels like to just give in and give up. It’s easy to think of exercise and eating healthy as a simple give and take, where the effort you put in directly correlates with weight lost, but this is simply not the case. Every time you step on the scale, you’re excited to see how much weight you’ve lost, but all too frequently, you’ve lost no weight, or even gained a bit, and with all that effort!
There’s nothing wrong with using the scale as a source of motivation, but don’t let yourself get caught up in numbers and strict goals. Allow your fitness regimen to be a process, and give in to that process. If you feel that the scale is a source or frustration for you, put the scale away for a week, or even two weeks, and just keep following your game plan. Come back a week or two later, look at yourself in the mirror and see if you notice any change. Take in your physique and recognize the benefits, then step on the scale. If you take time off from the scale, it makes it more likely that you will either see a noticeable change in your weight, a change in your shape, or both!
Dieting is a Lifestyle
That number on the scale represents only a microcosm of all of the changes that are going on in your body. The scale won’t tell you you have more energy. The number on the scale won’t make you feel better. The number on the scale doesn’t even accurately represent your body composition! Understand that all that work that you are putting in at the gym is not all for naught, if you are sticking with a good exercise and diet regimen, your body is truly going through a metamorphosis, even if the number on the scale remains the same for days or even weeks at a time! You are more than a number!
The difference in volume between a pound of fat and a pound of muscle is positively huge, and in terms of your physique, is more important than the amount of energy each pound of muscle that you burn. In addition to this, your muscles help constrain and control the way that fat distributes across your body, so it even makes the body fat you still have less noticeable!
Understanding the science behind weight loss, muscle mass, and metabolism makes it easier to withstand the effort involved in a successful exercise and nutrition regimen. In regard to physical fitness, knowledge truly is power. Don’t give in to the mental shortcuts like the scale that can discourage you and prevent you from reaching your goals. Just follow your plan, focus on gradual change, and appreciate the subtle positive changes in your physical and psychological health and in a matter of months, you’ll both look and feel like a new man (or woman)!
