Water is a natural appetite suppressant, helping to increase the body’s metabolic rate and metabolise stored fat.
Studies have shown that a decrease in water intake causes fat deposits to increase while an increase in water intake can actually reduce fat deposits, thereby reducing weight.
However this is only up to the recommended daily water intake, beyond this there is little to no effect. Diet and exercise are also important factors.
The kidneys require water to operate properly, lack of water stops them from operating to capacity with some of their work then needing to be done by the liver.
One of the primary functions of the liver is to metabolise stored fat into usable energy for the body. If the liver has to do some of the kidney’s work it cannot operate efficiently and as a result metabolises less fat, storing it in the body thus impairing weight loss.
