The body fat index calculator is used to determine the percentage of body fat. The percentage is a good indicator of body composition and health in most cases. For athletes, such as football rulers, excess fat doesn’t care so much about their health because they are physically active.
To define measurement, these types of calculators used estimates based on body measurements. However, a more accurate measurement involves underwater weighing or measuring the volume of a body in a reduced air chamber.
Fortunately, the measurement we get from the calculator is a fairly good indicator of the percentage of body fat.
In addition, you must specify that there are two types of fat: necessary and storage. Essential fat consistents of fat in areas such as the heart, lungs, liver, spleen, kidneys and intestines. Normal functioning in these areas requires fat.
On the other hand, fat containing fat is mainly found in adipose tissue. This includes surface fat, the main purpose of which is to keep us warm and protect our internal organs.
In addition, men and women on average have different percentages of fat, and women have more. The reason for this difference is probably related to biologically important functions for women, such as childbirth and other related functions.
As a result, when evaluating the percentage of body fat for women and men, different formulas should be used. In addition to sex, the following formula uses height, waist and neck size (in centimeters) to determine body fat percentage for men. For women, the formula also uses the same indicators, but also includes the measurement of their hip joint.
So, for men:
% BF = 495 / (1.0324-0.19077 (log (waist)) + 0.15456 (log (height)) - 450
and for women:
% BF = 495 / (1.29579-0.35004 (journal (waist + hip joint)) + 0.22100 (log (height)) - 450
Instead of calculating the formula manually, use this handy fat index calculator. And, as always, remember that information is always your best ally in your fat burning efforts.
