Body Fat Percentage Explained
Body fat percentage represents the proportion of fat in your body weight. The US Navy method uses body measurements to calculate this metric without expensive equipment. Body fat categories range from: Essential Fat (10-13% for women, 2-5% for men) for basic physiological functioning, to Obese (32%+ for women, 25%+ for men). Athletes typically have 10-20% body fat (women) or 6-13% (men). For general fitness, aim for 15-25% (women) or 10-20% (men). This calculator is non-invasive and practical—it requires only measurements of height, waist, hip (women), and neck. Body composition is more meaningful than weight alone, as muscle weighs more than fat. Combine this calculator with regular strength training for best results.
