How it's calculated
Uses the U.S. Navy circumference method, which estimates body fat from neck, waist (and hip, for women) measurements relative to height. Measure snugly with a soft tape, without compressing the skin. It's an estimate — accurate to within a few percent for most people, but not a substitute for a DEXA scan. Not medical advice.
