Body Fat Percentage Calculator
Body Fat =
Fat Mass =
Lean Mass =
Computes lean body mass and fat mass after entering your total weight and body fat percentage.
Body fat percentage can be estimated by using a body fat measuring device such as a scale, or by taking measurements with calipers, or by other means.
Every human requires a certain amount of body fat to survive. This healthy amount of body fat varies with gender, age, and other factors. Consult a licensed medical doctor to determine your proper weight and body composition.
It's normal for body fat percentage to vary between measurement devices and over several days. Don't panic - just use the average of three measurements taken in a month. And remember that you're a human being who is more than just a number.
This template is just for fun. I hope it inspires you to meet your fitness goals.
