It's true: Foods high in water can help you feel fuller on fewer calories, according to a new study from Pennsylvania State University in University Park. When meals and snacks--including pizza, muffins and casseroles--were altered to include more water-rich fruits and vegetables, women ate 23 percent fewer calories a day.

The participants, 24 women ages 19-35, say they felt just as satisfied as when they ate regular meals.
