Frequently Asked Questions
- How accurate is the Navy body fat method?
- The US Navy method is accurate within 3-4% for most people. It tends to be more accurate than BMI but less accurate than DEXA scans or hydrostatic weighing. For tracking changes over time, consistency in measurements matters more than absolute accuracy.
- What's a healthy body fat percentage?
- For men: 10-20% is the fitness range, 14-24% is acceptable, above 25% is considered obese. For women: 18-28% is the fitness range, 21-31% is acceptable, above 32% is considered obese. Essential fat minimums are 2-5% for men and 10-13% for women.
- Where should I measure my waist?
- Measure at the narrowest point of your torso, typically at the navel or just above it. Stand relaxed, don't suck in your stomach. Use a soft tape measure and keep it level. Measure against bare skin for accuracy.
