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 (the 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 and are easy to be converted into fat accumulation when eaten too much, which is not only difficult to lose weight, but also possible to "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, there are three series of fruits: red light, yellow light and green light. 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, not fat, and take away water, which leads to dull skin and lost figure. And because of single intake, malnutrition will also harm the body. This special report invites experts in melon and fruit research, nutrition and food safety, medicine, health care and other aspects, as well as the personal experience of fruit experts, to discuss the secret of beauty and slimming with the help of melons and fruits.
