Understanding Body Fat Percentage
Body fat percentage is the proportion of fat tissue relative to total body weight. Unlike BMI, it directly accounts for body composition, making it a more accurate indicator of fitness level. The US Navy method is a well-validated approach that uses simple body measurements.
Body Fat Categories (Men / Women)
- Essential Fat: 2-5% / 10-13%
- Athletic: 6-13% / 14-20%
- Fitness: 14-17% / 21-24%
- Average: 18-24% / 25-31%
- Obese: 25%+ / 32%+
Measurement Tips
- Measure in the morning before eating
- Use a flexible (cloth or plastic) tape measure
- Keep the tape level and snug, but not compressing skin
- Take each measurement 2-3 times and use the average
