Frequently asked questions
What is body fat percentage?
Body fat percentage is the proportion of fat mass to total body weight. Unlike BMI, it distinguishes between fat and muscle, providing a clearer picture of body composition. Healthy ranges differ for men and women.
What's a healthy body fat range?
Men: Athletic (6-13%), Fitness (14-17%), Average (18-24%), Obese (25%+). Women: Athletic (14-20%), Fitness (21-24%), Average (25-31%), Obese (32%+). Women naturally carry more fat for hormonal/reproductive health.
How accurate is the US Navy method?
US Navy method is within 3-4% accuracy compared to gold standard DEXA scan. It's free, requires only a tape measure, and is more accurate than BMI for body composition. For best results, measure carefully at consistent times.
How do I measure correctly?
Neck: just below larynx (Adam's apple), tape level. Waist: at navel level, relaxed (don't suck in). Hip (women): at widest point of buttocks. Use a flexible tape, snug but not tight. Measure 3 times and average.
Why is body fat better than BMI?
BMI doesn't distinguish muscle from fat. A muscular athlete might have BMI of 28 (overweight) but body fat of 10%. BMI is a quick screening; body fat shows actual body composition for fitness and health goals.
Can I lose body fat without losing weight?
Yes — through 'recomposition'. Build muscle while losing fat. Requires strength training + adequate protein + slight calorie deficit. Slower process but better aesthetic results. Common in beginners and those returning to training.
What's essential body fat?
Essential fat is needed for survival: organ protection, hormones, vitamin storage. Men: 3-5%, Women: 10-13%. Going below is dangerous — causes hormonal issues, organ failure risk. Female athletes risk amenorrhea below 14%.
How fast can I lose body fat safely?
Sustainable rate: 0.5-1% body fat per month. For a 80kg person at 25% bf, losing 1 kg fat per month is realistic. Faster loss usually means losing muscle too. Patience and consistency win.
