First of all, diet. I suggest you drink milk in the morning, eat baked sweet potatoes or baked potatoes, eat apples, bananas, a little rice and light dishes at noon, and eat corn porridge and steamed bread for dinner.

Then there is exercise. It is best to wrap the dissatisfied parts with plastic wrap and skip rope for half an hour every day (if time does not allow, you can do it three times a week). Not difficult. Stick to it, and it will have obvious effect in one month.
