It is exercise+dieting. We must persist. The first is to control diet. Don't eat high-calorie foods such as fried dough sticks hamburgers in the morning, and eat more fruits and whole wheat bread. Eat less meat and be vegetarian at noon until you are full. Drink a bowl of porridge or eat a banana at night. Do more exercise while controlling your diet. Jog for 30 minutes every day, and do more stretching exercises after running to avoid thickening your calves. Sit-ups or hula hoops are the best way to get rid of abdominal fat as soon as possible. If you really don't want to exercise! Recommend an app called Postpartum Body-building Class, which has a professional weight-loss exercise video, and follow the exercises inside. Very relaxed and not tired. But we must stick to it. Otherwise, nothing will work.
