The amount of fat in the body is the fourth element that determines the level of physical fitness for each individual. Excessive
calories are stored in the form of fat. As our age passes we become less active and the metabolic rate begins to decline. 

At 70, we need 15 percent less calories than we need at age 20.
Overweight causes excess pressure on the bones, ligaments and muscle tissues that carry fat. Keeping your body weight keeps your body from carrying this extra weight, making you feel easily in motion and doing different activities.
