Water suppresses the appetite naturally and helps the body metabolize stored fat.
The kidneys cannot function properly without enough water. When they do not work to capacity, some of their load is dumped on the liver. One of the liver's primary functions is to metabolize stored fat into usable energy for the body. But if the liver has to do some of the kidney's work, it cannot work at full throttle. Drinking an adequate amount of water every day is the best treatment for fluid retention.
