Eat a balanced diet and have seven full meals. You'd better keep standing after eating. You can choose to take a walk or pack your things. In addition to reducing fat accumulation, it can also help digestion, because if you don't move within 30 minutes after a meal, it is most likely to form abdominal fat. You can also do sit-ups, practice yoga, swim and run according to your own situation. Pay attention to scientific exercise and persist for a long time.
