In one study, a group of obese women ate a reduced-fat diet high in water-rich foods such as watermelon. The other group reduced only their fat intake. Although both groups lost weight over the course of the year, the water-rich group lost close to three pounds more and reported feeling less hungry than the people in the group who ate the reduced-fat diet.

By eating water-rich fruits and vegetables, the participants were able to eat 25 percent more food by weight without adding calories. This increased food intake likely made it easier for them to stick to their diet and lose more weight.
