Drinking water can help you lose weight. (and the only thing that counts as water is water)
Now more then ever is it important to keep drinking water. 1 quart (32 oz, or ¼ of a gallon) for ever 50 lbs of body weight. Or 1 liter for every 20 kg of body weight.
Make sure it is purified water
When it comes to losing weight, we often need to use every trick in the book. And according to researchers from Virginia Polytechnic Institute and State University, one of those tricks might be having a little H2O before you eat.
Researchers had young (ages 21-35) and old (ages 60-80) subjects drink 1.5 to 2 cups of water 30 minutes before a meal. They were then allowed to eat as much food as they wanted. The researchers compared the results to the amount they ate during a meal without the water.
Drinking the water did not affect how much food the younger subjects ate [it just made them healthier, gave them more energy, and helped them sleep better], but it reduced the older subjects' food intake by about 10 percent. And it worked particularly well to curb the appetites of older men.
If you're over 35, grab a glass of water before you sit down to eat. It won't replace the need for a good diet and exercise. But it might help you control your appetite
