In this regard, Xin Li, the first five-star personal trainer in China and a personal nutritionist at Jade Bird Fitness Club, believes that half a watermelon (pulp weighs about four or five kilograms) generates about 680 calories, which is equivalent to three bowls of rice. Fruits are not all low in calories, such as cantaloupe, watermelon, pineapple, papaya and other fruits, which have high sugar content. If you eat too much, it will easily turn into fat accumulation, which will not only make it difficult to lose weight, but also may "gain weight".

Ximu, deputy director of China Health Care Expert Committee and Peking University China Medical Economic Research Center, said that in terms of sugar content, fruits have three series: red, yellow and green. During weight loss, bananas, pineapples, watermelons and other fruits with high sugar content should be strictly avoided.

Xin Li said that nowadays people generally lose weight, instead of fat, which takes away moisture, resulting in dull skin and out of shape. And because of single intake, malnutrition can also cause harm to the body.
