The human body is composed of ~75% water, which plays an important role in every bodily function. Hydrated a person is more efficient in body performance ranging from thinking to burning body fat. Water intake aids in weight loss. It suppresses appetite, boosts metabolism, and makes exercise more effective. Drinking more water promotes satiation, as it passes through the system and stretches the stomach, resulting in fullness. Drinking water also stimulates heat production in the body, resulting in a higher rate of metabolism.
