Understanding Body Fat Percentage
Body fat percentage is the proportion of fat in your body compared to everything else including muscle, bones, water, and organs. Unlike BMI, it provides a more accurate picture of your fitness level and health.
Healthy Body Fat Ranges
Men: Essential 2-5%, Athletic 6-13%, Fitness 14-17%, Average 18-24%, Obese 25%+
Women: Essential 10-13%, Athletic 14-20%, Fitness 21-24%, Average 25-31%, Obese 32%+
Navy Method
This calculator uses the U.S. Navy circumference method, which estimates body fat based on measurements of waist, neck, and hip (for women). While not as accurate as DEXA scans, it provides a good estimate for most people.
Quick Tips
- BMI alone doesn't reflect overall health
- TDEE varies based on activity level
