What is Body Fat Percentage?

Body Fat Percentage is the total mass of fat divided by total body mass, multiplied by 100. Unlike BMI, which assumes weight is bad, Body Fat Percentage distinguishes between muscle and fat.

A person can have a "Normal" BMI but a high body fat percentage (often called "Skinny Fat").

Why the U.S. Navy Method?

The U.S. Navy Method is widely considered the most accurate non-clinical way to estimate body fat. It uses specific body measurements (Neck, Waist, and Hip) to calculate body density.
