Why does body fat increase with age?

A tendency to lose some muscle and strength, and to add to the percentage of body fat -- often described as increasing body fat composition -- is a normal part of the aging process. Typically, exercise capacity declines as we age.

If you want to age successfully, with improved strength and endurance, you need to understand the other changes associated with aging. Your body burns calories even when you are resting, and this process becomes more efficient as you age. In other words, the amount of energy your body uses at rest decreases as you get older.
