Now comes scientific evidence that H2O really does help you lose weight. Researchers in Germany report that water consumption increases the rate at which people burn calories. The impact is modest and the findings are preliminary, but the researchers say their study could have important implications for weight-control programs.
Some dieters find it helpful to drink a glass of water when they feel hungry between meals, or just before a meal. However, I do not recommend this as a regular appetite-reduction tactic. Firstly, because hunger is an important indicator of low blood sugar, which water can do nothing to correct. And if blood sugar falls too low, it can lead to irresistible urges to eat junk food or binge. Secondly, drinking water purely to fill up your stomach is merely an artificial short-term measure which does nothing to help create the sort of eating habits that are essential for long term weight control.
Drinking water is important if you're trying to lose weight, some studies have shown that thirst and hunger sensations are triggered together. If there is a slight dehydration the thirst mechanism may be mistaken for hunger and one may eat when the body is actually craving fluid. As most food contains some water, if one doesn't drink much they may be subconsciously driven to eat more to gain the necessary water supply however, you also gain the undesired effects of increased calorie consumption. Drinking more water can help to prevent overeating and benefit weight loss.
The body maintains a healthy fluid balance by a complex cell mechanism involving sodium, potassium and other electrolytes. In simple terms, if you eat too much salt (sodium) you will retain more water, leading to weight gain. Anyone who suffers from fluid retention and accompanying swelling (edema), especially women who experience premenstrual symptoms (PMS) or obese men with high blood pressure, is advised by dietitians to follow a low sodium diet (eg. the DASH diet). Ideally, limit your intake to 1000 milligrams of sodium per day, until the water retention eases.
