When snack time rolls around, do you have a hard time knowing when to say when? Then your challenge is to drink water before you start eating. Drinking eight ounces of water will help to fill up your stomach so when you're done with your snack, you won't be hungry.
Another benefit of drinking water? You can actually burn a few extra calories in the process. A recent study showed that drinking half a liter of water briefly raised participants' metabolisms, causing them to burn 25 extra calories.
