What method can reduce the fat on the stomach

The doctor replied:

first of all, we should control our diet. We should have a light diet. We can eat fresh vegetables and fruits, but don't eat foods with high calories. We should also properly carry out some physical exercise every day, such as rope skipping, playing badminton, turning hula hoops or doing push ups. If we stick to it for a long time, we can reduce the fat on our stomach.
