Water naturally suppresses the appetite and helps the body metabolize stored fat. An increase in water intake will reduce fat deposits. One of the roles of our liver is to convert stored fat to energy. Because our kidneys can’t function properly without enough water, if we don’t have enough water in our systems, the liver steps in and assists kidney function. This results in the liver not being able to metabolize fats as quickly and efficiently as it did when it was not assisting the kidneys. As a result, it metabolizes less fat; more fat remains stored in the body and weight loss stops.
