Keep exercising. Drink plenty of water (usually 8 glasses of water) and take a walk every day. Even if you have a car, you should walk with a belly to prevent you from getting too full every time you eat. You usually stop eating after 6 pm. Don't sit down immediately after eating. You should stand 1 hour or so. It is also to prevent your stomach from often doing some aerobic exercise, such as jogging or yoga, so as to keep in good shape!
