Standing helps to relax the stomach. Be careful not to drink water within half an hour after meals, because water will dilute the gastric juice, which is not conducive to the normal work of the stomach. 45 minutes after a meal is the best time to exercise to lose weight, but pay attention to gradual exercise. If you don't exercise for half an hour, you won't burn fat, but you will lose water and stick to it; The interval between exercises should not exceed 72 hours, otherwise you will have to start again.
