Be sure to eat breakfast, lunch, less dinner, drink some water before going to bed, do sit-ups every night, and don't eat junk food and snacks.

Eat more fruits.

Do sit-ups, the more the better, just make sure you sweat, the effect is very good, and it is simple and easy to do, and it is also good for sleep. If you have poor willpower about food, I suggest you drink a glass of white water before meals.

Remember to insist. Oh, just stick to it.
