About Body Fat Percentage
Body fat percentage is the total mass of fat divided by total body mass, multiplied by 100. It is an important indicator of health and fitness, as it takes into account the composition of the body rather than just total weight.

For Men:
- Essential: 2-5%
- Athlete: 6-13%
- Fitness: 14-17%
- Average: 18-24%
