First, be careful not to eat snacks. If you have the habit of eating snacks, you can drink a little water when you want to eat snacks, without hurting your stomach, and you can control eating snacks.

Secondly, eating a little coarse grains, such as corn porridge, for breakfast every day can reduce the glucose conversion index, and you won't feel hungry at noon, so you won't eat much at lunch.

Third, you can eat some fruit before meals, such as eating an apple or a peach first. It is best not to eat pears, so as not to affect the absorption of vitamins. You can also drink some soup first. In this way, the amount of food eaten at dinner will be reduced accordingly, which can effectively prevent obesity.

Fourth, try not to be too full when eating. Therefore, don't eat too fast, because people often feel full after eating for 20 minutes. If they eat too fast, they can easily overeat.
