Although it isn't exactly the same, it helps to think about water the same way you think about stored body. Your body tend s to hold onto water when it's thirsty much like how it holds onto stored fat when your hungry.

We all know after dieting for awhile, our body shifts into starvation -- our metablosim slows to conserve energy and holds onto fat presuming its needed to survive.

Well, water seems to work the same way...when we don't get enough, our body begins to conserve it, and we retain water. So when we drink a lot of water, our body adjusts "knowing" that plenty of water s entering our body regularly and doesn't need to coserve it as much.

Our body also knows it needs a sufficient amount of water to process stored body fat for energy and flush out the byproducts. Thus, when we don't drink enouh water, our body also burns fat more slowly, "knowing" water is being conserved, it slows the fat metabolism process as well.

I know that's a bit oversimplified, but helps to understand why sufficient water is so important in the weight loss equation.
