Body fat percentage measures fat mass as a proportion of total body weight. The US Navy method estimates body fat using circumference measurements (neck, waist, hip). Healthy ranges differ by gender and age. Essential fat minimum is 2-5% for men and 10-13% for women; dropping below these levels is dangerous.
