Why is it important to know body fat?
Just knowing your weight is not enough. A person may look thin but have a high body fat percentage — which can increase health risks. On the other hand, someone who is overweight may have less fat and more muscle. So body fat is an important indicator in measuring health.
Knowing the correct body fat will help you understand:
-
Are you at a healthy weight?
-
How well your diet or exercise plan is working
-
Your body's fitness level
