Summary Introduction
To review:
Whether the total body water will increase, decrease or stay the same when someone starts a diet and exercise regimen and lose 30lb (pound).
Introduction:
Water is needed by the body to maintain homeostasis, a condition of balance in the body’s internal environment. The body should be properly hydrated in order to maintain this balance which totally depends on the amount of fluid present in the body.
