I won't say much about diet, just eat the same food in peacetime, and you can reduce it a little, but don't eat too much, and try to avoid rebound in the future.
Finally, running is a whole-body exercise. Of course, it is effective all over the body. If you have a lot of meat on your stomach, you can choose to add some sit-ups or hula hoops after running, but you should stretch your muscles within 6-7 minutes after running. You can also choose skipping or aerobics, but the time should be more than 20 minutes.
In addition, it is king to try not to be too tired at first, and then influence the positive mood of exercise and gradually increase the amount of exercise.
