Here goes... Water suppresses the appetite naturally and helps the body metabolize stored fat. a decrease in water intake will cause fat deposits to increase, while an increase in water intake can actually reduce fat deposits. The kidneys can't function properly without enough water. When they don't work to capacity, some of their load is dumped onto the liver. One of the liver's primary functions is to metabolize stored fat into usable energy for the body. But, if the liver had to do some of the kidney's work, it can't operate at full throttle. As a result, it metabolizes less fat, more fat remains stored in the body and weight loss stops. Drinking enough water is the best treatment for fluid retention. When the body gets less water, it perceives this as a threat to survival and begins to hold on to every drop. Water is stored outside the cells. This shows up as swollen feet, legs and hands.
The best way to overcome the problem of water retention is to give your body what it needs - plenty of water. Only then will storedd water be released. The overweight person needs more water than the thin one. Larger people have larger metabolic loads. Since we know that water is the key to fat metabolism, it follows that the overweight person needs more water.
Water helps to maintain proper muscle tone by giving muscles their natural ability to contract and by preventing dehydration. It also helps to prevent the sagging skin that usually follows weight loss - shrinking cells are buoyed by water, which plumps the skin and leaves it clear, healthy and resilient.
Water helps rid the body of waste. During weight loss, the body has a lot more waste to get rid of - all that metabolized fat must be shed. Again, adequate water helps flush out the waste...
