A [?] diet is required to provide the body with the correct amounts of nutrients and energy. The amount of energy required by the body depends upon a number of factors. These factors are the body [?], the degree of [?], and the rate of [?] of the body. The energy used when the body is resting is called the [?] Metabolic Rate (BMR). This energy is needed to keep the heart [?], the lungs working, and to keep the [?] of the body constant. Energy is also needed for the [?] reactions that are needed in the body.
