The difference between fatness and overweight?

The 2 concepts are not the same. Overweight is the case when the weight of the bones and the muscles does not meet normal measures. A bodybuilder having huge muscles, or a heavy-limbed person may have heavy weight compared to their height.

Fatness when overweight is composed of excess amounts of fat. Therefore, fatness is defined by the body's fat content. Fatness is defined when the body's fat percentage is over 20% for men and over 25% for women.
