And pay attention when eating watermelon. It is best not to eat at night. It is not advisable to eat about 4 hours before going to bed. Take watermelon as an example. You eat some watermelons before you go to bed. These watermelons need to be digested after they reach your stomach. You should go to bed after eating. You don't do much exercise when you sleep, so most of the sugar in watermelon can't be digested and absorbed by you, so these undigested sugar will be converted into fat and accumulated in your abdomen. In the long run, there will be more and more meat on your stomach.
Therefore, eating watermelon may not necessarily make you fat, but you should master the time and quantity of eating watermelon. Eat no more than 2~3 pieces of watermelon a day. Eating half a piece or even a piece a day will definitely make you fat. Moreover, it is best to eat watermelon in the afternoon, because eating watermelon will make you feel full. If you eat it before meals, you can't eat any other meals, so you'd better eat it after meals or in afternoon tea, so that you won't get fat or affect your normal eating.
