Everything you need to know about body composition
The US Navy Method is a scientifically validated formula used by the military to estimate body fat percentage using simple circumference measurements. It's accurate within 3-4% for most people.
Body fat percentage is a better health indicator than weight alone. High body fat increases risk of heart disease, diabetes, and certain cancers, even if your weight seems "normal."
For men: 10-20% is healthy. For women: 18-28% is healthy. Athletes may have lower percentages. Essential fat (needed for survival) is 2-5% for men and 10-13% for women.
