Water has many functions in the body. In fact, “70% of the human body” is made up of water. Water helps to remove toxins from the body, aids in absorption, regulates body temperature, circulation and excretion. It also assists in the “utilization of water soluble vitamins.” Water also plays a vital part in losing weight and maintaining weight loss. It does this by suppressing the appetite and aiding in metabolizing fat. According to Donald S. Robertson M.D., M.Sc author of The Snow Bird Diet, says studies have shown that if water is decreased in the diet, it will cause fat deposits to increase. However, drinking water can reverse the affects. When water is not consumed in optimal amounts, the kidneys are not able to function properly. When this happens, waste is passed on to the liver to metabolize. The main function of the liver is to metabolize fat into forms of energy the body can utilize. This is intercepted when the liver has to do the work of the kidneys. This results in less fat being metabolized by the liver. Water also helps to reduce fluid retention. This happens when not enough water is consumed so the body goes into survival mode and retains water. Water also helps with muscle tone by allowing the muscles to stay hydrated and contract with ease. In addition, water helps with sagging skin from weight loss by allowing shrinking cells to hydrate which plumps up the skin leaving it with a healthier appearance.
Most people should drink 64oz of water a day but this can vary based on sex and weather conditions.
