What is body fat?

If you want to assess your health it is important to know composition of your body. Therefore, it is necessary to determine the quality (not the quantity of your body weight). Your body weight is divided in two main components:
– Lean body mass: weight of your bones, muscles, water, etc..
– Body fat: weight of extra fat.
Body fat is then divided into two categories. Essential fat, which is needed for different processes in your body, and the extra fat that is stored in your body as a result of excessive calorie intake.

If you want to lose weight in a healthy way you must get rid of that extra fat that your body stored.

Body fat percentage chart

Description Women Men
essential fat 10-13% 2-5%
athlete 14-20% 6-13%
fitness 21-24% 14-17%
average 25-31% 18-24%
obese more than 32% more than 24%

For men, everything between 5 percent and 20 percent is healthy, whereas for women everything between 15 percent and 30 percent is healthy.
Having very low body fat percentage is as dangerous as having a high body fat percentage.
Women tend to have more body fat than men. This is natural. For visible abs, men should have around 15 percent of body fat (or lower), women should aim for 20 percent (or lower).

    The process on how to calculate body fat percentage is very easy and would not need a mathematical genius to do. It is very simple and you can do it yourself conveniently. What we need to do is first weigh ourselves and record it. Make sure that you take note of the correct numbers indicated by the weighing scale and then multiply your weight by 703. After which, you need to measure how tall you are. You need to get the correct height in inches. Then whatever you get after measuring it, you need to multiply it by the same number. For instance if your height is 67 inches then you need to multiply it by 67 also. Lastly, divide the product you got for your weight by the result you got for your height.

    Converting BMI to an assumed body fat percentage really defeats the purpose of calculating body fat percentage; you might as well just take your BMI result and go with that interpretation. I also find it ironic that the article says you should assess your health by determining the quality, not quantity of your weight, and then the calculator just compares your age and gender to a number based solely on the quantity of your weight for your height and returns an assumed “body fat percentage” (I put this in quotes because the assumption is very far-fetched when it comes to those of us who are most likely to want to calculate our body fat percentage — that is — those of us who have muscle; especially in large quantities). It is also ironic how there are pictures of supposed physiques for various body fat ranges and I have never seen someone with a sub-14 BMI (those who would get a calculation of around 3-4% by this calculator) who looked like a professional bodybuilder. I have a friend who has a BMI of 12.8 and his body fat percentage would come out in the 2% range by this calculator, but he is a twig, not a professional bodybuilder (yes, he’s human; he is not a literal twig, just an ectomorph).

    However, I have a BMI of 28.0; so apparently 21.5% body fat. So I apparently should have a sagging waist as the picture indicates. But I don’t. In fact, my actual body fat percentage is actually closer to the 14-15% range. Four circumference methods that I know of and the calculation of my body fat percentage based on those methods are Covert Bailey Method, 14.250%; U.S. Military Method, 13.903%; YMCA Method, 14.800%; and Modified YMCA Method, 16.765%. My skinfolds come closest to the YMCA Method. These equations can be found at http://hubpages.com/hub/Five-Methods-to-Calculate-your-Body-Fat-Percentage-by-Using-a-Tape-Measure .
