Why drink more when dieting?

* Drinking a big glass of water whenever you feel hungry and before a meal or snack fills the stomach briefly and makes you feel fuller and stop eating sooner.
* Breaking down body fat and body muscle during weight loss produces wastes that must be eliminated through the kidnys. Drinking enough water is important to keep the kidneys functioning to remove these wastes.
* Popular high-protein diets produce more waste products from digestion, let alone from breaking down stored fat. Kidney function is even more important when on a high-protein diet.
* Drinking more water does not "flush fat".
* If the dieter is drinking plain water, he/she is less likely to be drinking somethng with calories in it.

Drinking water briefly increases metabolism. Drinking 500ml, of water (a half-liter or about a pint)increased the study participants' metabolism briefly-for about a half hour. In that time they burned an extra 25 calories. That's about a quater of a piece of sliced bread, or 5 M&Ms. The researchers theorized that most of the effect comes from warming the water in the stomach. In the male participants the calories came mostly from stored fat, in the woman it came from stored carbohydrates.
