A study shows that dieters who down two glasses of water before each meal shed more pounds than those who only count calories. While prescription-only weight-loss drugs cut the body’s ability to absorb fat or tinker with the brain’s chemistry, water simply fills up the stomach. Water is also, of course, calorie-free and readily available. Water drinkers ate 75 to 90 fewer calories per meal. Over the course of a day, this could amount to almost 300 calories - the equivalent of a Danish pastry or a pint and a half of beer.
