Why drinking water helps you dietStudies have shown that drinking water reduces your apetite, especially if you drink 8 to 16 ounces right before a meal. It makes sense that if there is something in your stomach that you will not be as hungry. The water will not help you burn fewer calories, if just allows you to feel full with fewer calories, so prepare smaller meals and drink water before you eat.
Replacing other drinks with water is the easiest way to cut calories out of your diet. Instead of drinking soda, juice, milk or something else with your meal, drink water. You don't need those calories, and you will be better hydrated and feel better if you just drink water.
Don't just drink water right before and during meals, drink it all the time and your whole body will feel better. After a few weeks your body will start craving water all the time. I think this state of super hydration makes sticking to your diet easier. The only downside is frequent trips to the bathroom.
