Total Body Fat
Body fat percentage is a measure of fitness level.
You need body fat to insulate you and to protect your organs and joints. However, it is unhealthy to have too much or too little fat.
If your body fat percentage is too low, your resistance to diseases and your energy levels are lower, and you are at risk of health issues. If your body fat percentage is too high, you have a higher risk of health problems.
It is therefore important to calculate your body fat percentage, and stay in the healthy range.
