Nutrition and physical activity go hand in hand. The working body demands energy-yielding nutrients to fuel activity. And, it needs protein plus supporting nutrients in order to build lean tissue.
Exercise requires the body to dip into its stores of duel- namely, fat and glycogen (sugar). By using up fat and building lean tissue, exercise pushes body-composition toward lean and thus, raises the body's rate of energy expenditure (metabolism).
To the contrary, a lack of exercise, or an "exercise deficiency" can lead to accelerated development of the diseases associated with sedentary life- cardiovascular disease, obesity, intestinal disorders, apathy, insomnia, accelerated bone loss, etc.
