First of all. Of course, you must ensure that three meals a day are regular. Eat less meat. You can eat some meat in the morning, and dinner is free. One hour before lunch and dinner, eat some fruits, apples, bananas and so on. Chew slowly when eating. Eat dinner until you are six points full.

Pay attention to exercise in peacetime. You don't have to deliberately. Just don't sit too long. Try to move and walk instead of taking the bus when you can. I believe you will achieve results. . .

I hope my answer can help you. ! ! !
