What is Body Fat Percentage?
Body fat percentage is the proportion of fat tissue relative to total body weight. Having a healthy amount of body fat is essential for thermal insulation, organ protection, and energy storage. However, excess body fat is associated with health risks including heart disease, type 2 diabetes, and hypertension.
U.S. Navy Method
The U.S. Navy method estimates body fat using circumference measurements — waist and neck for males, plus hip for females — along with height. The formula uses logarithms of these measurements to produce an accurate estimate. It's a practical, accessible alternative to more expensive methods like DEXA scans or hydrostatic weighing.
