Understanding Body Fat Percentage: Theory, Usage, and History
What is Body Fat Percentage?
Body fat percentage is the proportion of your total body weight that consists of fat tissue. Unlike BMI, which only considers height and weight, body fat percentage provides a more accurate assessment of body composition by distinguishing between fat mass and lean mass (muscle, bone, organs, and water).
Body Fat Categories (Men/Women):
- Essential Fat: 2-5% / 10-13%
- Athletes: 6-13% / 14-20%
- Fitness: 14-17% / 21-24%
- Average: 18-24% / 25-31%
- Obese: 25%+ / 32%+
