1, more than 94% of watermelons are water, and their sugar content is very high, so the calories of watermelons are very high. The calories of watermelons are 250 kcal/kg, while the calories of a bowl of rice in an ordinary family are about 200 kcal. Eating a watermelon is equivalent to eating five or six bowls of rice. If you eat watermelon in the amount of 1 apple, it is not easy to produce obvious fattening effect, so it is forbidden to eat too much watermelon.

2, can't eat watermelon as a midnight snack.

Watermelon is rich in sugar. If you eat too much before going to bed at night, it will increase insulin and promote fat synthesis. Most of the newly synthesized fat in the human body is stored in the abdomen. In addition, the amount of exercise at night is reduced, and the fat is only stored and not consumed. After a long time, a small belly grows.

3. Don't overeat watermelon because you don't feel full.

The sweetness of watermelon mainly comes from fructose. The lower the temperature, the greater the sweetness of fructose. It is found that fructose does not significantly increase blood sugar, but it also bypasses the mechanism of appetite control. Since watermelon contains a lot of fructose, it also has the characteristic of not feeling full. Therefore, it is difficult for people to control their food intake when eating watermelon, so we must remember that watermelon can make you gain weight, and don't overeat watermelon because you don't feel full.
