Eat less, and it is best not to eat snacks, especially desserts and greasy food. Don't eat three hours before going to bed, it's easy to get fat. Walk more after dinner, don't be lazy, and you'd better do more exercise. Don't let yourself be idle. You can buy a hula hoop. You can stand on the ground and shake your waist and stomach for a long time, which will have a good effect on reducing the meat on your stomach and making your legs shake.
