I found this article and thought I would share it. It's a more eloquent way of describing what I would really like to describe.
Stepping on the bathroom scale is a daily ritual for many dieters, athletes and fitness enthusiasts. After all being healthy and in-shape means weighing less, right?
Scales seem to be everywhere: The home bathroom, the gym or health club locker room, and – of course — the doctor’s office. We’re a society increasingly obsessed with our weight, but ironically, one that is becoming fatter than ever.
But what if you knew that your trusty scale was deceiving you? What if you found out that losing a pound or two (or even five) doesn’t mean you’ll look any thinner or more in-shape? What if I told you that losing weight is actually making you fatter?
WHY WEIGHT LOSS SHOULD NEVER BE YOUR GOAL
Our preoccupation with moving that pointer on the bathroom scale down closer to zero is at the root of most people’s frustration with becoming healthier and more fit. Crash diets, fad diets, endless hours of cardio, extreme calorie restriction and eating disorders can be traced directly to our desire to step on the scale and see that we’ve lost weight.
Yet the number that you see on the scale each morning is a terrible indicator of body composition. Weight alone can’t tell you anything about the distribution of that weight. It doesn’t take into account the ratio of fat to lean tissue, which can cause very lean people to think they are fatter than they really are, and fat people to think they are leaner.
In other words, losing weight can actually be a bad thing, especially if you are doing it at the expense of lean tissue like muscle. If all you are using to gauge your fitness progress is scale weight alone, you are only getting half-the-picture.
UNDERSTANDING BODY FAT PERCENTAGES
Body fat percentage is the only truly accurate way that you can measure your body composition.
Forget about how much you weigh or what your BMI (Body Mass Index) is. Instead, focus on your ratio of lean tissue to body fat. Once you do this, you’ll actually start looking and feeling better. And it will change your mind about the long-term effectiveness of crash diets and the basics of your workout routine.
BODY FAT PERCENTAGE ISN'T ROCKET SCIENCE
Your scale weight is a measure of your body’s total weight: this includes body fat; lean tissue like muscle; your internal organs like the heart, lungs, and liver; the food and liquid currently passing through your digestive tract; water retained by body tissue; and skeletal material like bones and their connective tissue.
The number the scale displays when you step on it doesn’t make distinctions between the types of weight it is measuring. It just lumps it all together.
But it should make distinctions.
A person can actually have a high body weight on the scale, but be extremely lean. I know this runs counter to what you’ve heard, but it’s true. What really matters is how much body fat you have sitting on top of all of that lean tissue and skeletal and connective material. If you have a lot of body fat, you’ll appear “fat” and bulky, if you have very little, you’ll look “lean” and slim.
And here’s the key point: This holds true regardless of your weight.
THE DIFFERENCES BETWEEN BODY FAT and MUSCLE
Body fat (adipose tissue) is metabolically inactive. This means it’s primary function is to store calories, not to consume them. A pound of fat burns around 2 calories per day to maintain itself. The purpose of body fat is to store energy (in the form of excess calories) for use later, when food is scarce. This is an evolutionary adaptation based on the way we lived thousands of years ago, when the availability of food was spotty.
But today, people can consistently consume enough calories (and often more) to maintain their basic functions.
Fat storage is not as critical as it once was, yet we continue to eat as if famine was just around the corner. Even worse, changes in our diet from whole grain, complex carbohydrates to highly-processed foods have encouraged our bodies to store more calories as fat, even though it’s unlikely we will ever need them.
Muscle, on the other hand, burns around 6 calories per day — and that is at rest.
Exercise the muscle (for example, during weight training) and you can burn an upwards of 250 calories, depending on your existing levels of lean body mass.
WHY FAT MAKES YOU LOOK FATTER, AND MUSCLE MAKES YOU LOOK LEANER
Your body displays fat and muscle differently. One pound of muscle looks very different on the body from one pound of fat. Muscle makes you appear leaner, while fat just … well … makes you look fat.
Increasing your ratio of muscle to fat can make you look more in-shape, even though the scale may say you are heavier. Likewise, you can actually lose a lot of weight, and look extremely out of shape. Fitness trainer and natural bodybuilder Tom Venuto calls this the “fat skinny person” syndrome.
This is why looking only at the weight on a scale lies.
BODY FAT ILLUSTRATED: THE PROOF IS IN THE PICTURES
The best way to illustrate how muscle itself make you look more lean, versus scale weight is to see some actual real-world examples.
Let’s take a look at two picture to see why.
First, let’s look at Nicole Richie (she is about 5′ 1″ and around 95 lbs in this picture):
Now, take a look at someone like Michelle Parker, a fitness model with the exact same height as Nicole Richie, but she weighs ten pounds more in this picture:
One more great example: fitness model and actress Amanda Carrier. Amanda is 5′5″ and says her weight is usually between 125-130 lbs at 14-16% body fat.
No one would ever accuse Amanda (who is also a professional swimwear model) of being overweight. Yet, her scale weight might surprise many people who assume she is much lighter than 130 (a very healthy, lean weight, by the way.) Even more impressive, Carrier says she is able to more or less maintain that body fat level without going through the draconian bulking and cutting cycles of female fitness figure competitors.
So you tell me who is in better shape? Which of the three has those coveted great abs and amazing tone and muscle definition?
WEIGH MORE AND LOOK BETTER? WHY WEIGHT ALONE IS DECEIVING
Nicole Richie clearly weighs less. But I would estimate that Michelle, Jen and Amanda have at least 1/3 more muscle mass than Nicole and weigh 10-20 lbs more (which is actually a substantial difference at their height.) And neither of them look “bulky” or overly muscular. In fact, they probably represent what most women would consider to be an “ideal” bikini-ready body.
Yet, if you depended on scale-weight alone to determine body composition, Michelle and Jen would lose out to Nicole Richie, which would be clearly absurd and inaccurate. And because Michelle and Jen carry more muscle, they are more metabolically-active than Nicole Richie. That means that even at rest, they burn more calories naturally than Nicole (and therefore, can actually eat more.)
Think about that for a second. The heavier of the two actually burns more calories doing nothing more than the lighter woman because they have more muscle.
Extreme calorie restriction has left Nicole with little muscle mass, which translates into a flat, boney appearance. Bottom line is that she looks unhealthy compared against Michelle and Jen, who are fit, toned and clearly in great physical shape.
My point here is not to pick on Nicole Richie, who clearly is struggling with an eating disorder, but rather to show that by constantly focusing on bodyweight, many people sabotage their ultimate goal of improving their appearance and becoming more healthy and fit overall.
BODY FAT BY THE NUMBERS
Let me give you one more example, with numbers, to illustrate what I’m talking about.
Let’s look at two men of the same age:
Jim weighs 170 lbs with 20% body fat. Mark weighs 175 lbs (5 lbs more) at 10% body fat. This means Jim has 11 lbs of fat on him, while Mark — even at the higher weight — carries only 5.5 lbs of fat. Which of these two people will look leaner, despite the difference in scale weight?
Mark will. He has less fat, which means better muscle definition.
So again, the scale lies.
This is why using the scale alone to determine body composition and appearance is a dead-end.
Body Fat Percentage: A Better Goal
A much better approach is to look at your percentage of body fat compared against your total weight. Once you start thinking this way, that daily weigh-in becomes much less important.
Your goal should never be to lose weight, it should be to lose fat.
In the course of stripping off fat, you typically will lose some scale weight (along with some muscle,) but your objective should always be to maximize fat loss, while minimizing muscle loss.
If you lose too much muscle along with the fat, your body fat percentage can actually remain the same (or even increase slightly.) And that isn’t progress, even though the scale tells you that you are lighter.
DID YOU KNOW? Although a pound of fat and a pound of muscle weight exactly the same, a pound of fat has more volume and takes up more space on your body.
An ideal scenario would actually be to see your body fat percentage decrease, while your scale weight remains stable. This means that you are losing fat, without losing and muscle (and in this scenario, you would have actually gained some muscle.) However, this almost never happens because it is difficult to gain muscle and lose fat simultaneously. So a more realistic goal would be to see moderate weight loss accompanied by a decrease in body fat.
If you find yourself losing weight, but not losing much body fat in the process, then you need to either change your diet or your workout routine. The most likely culprit is that you’ve restricted calories too much and your body is tapping muscle for fuel. This can be the start of a vicious cycle, because with less muscle, you actually burn fewer calories. And burning excess calories is necessary to lose fat.
