In terms of its nutrition and function, watermelon promotes diuresis and digestion, and the water in watermelon accounts for the vast majority. Therefore, watermelon can accelerate metabolism, detoxify and nourish skin, and can help eliminate excess water in the body. At the same time, it does have the effect of losing weight for some people, but don't eat more, because watermelon is still rich in sugar. Eat a moderate diet and eat more apples and bananas.
