Eat less, drink water if you want, or eat a gum. Don't chew for too long. Chewing gum will chew air into your stomach, which will enlarge your stomach and reduce your desire to eat. You can't help eating fruit.
Remember to do exercise, sit-ups are good, and turn hula hoops. Try to keep your back straight when sitting, so that meat is not easy to accumulate on your waist, and you have to stand for half an hour after eating, so that meat is not easy to accumulate. Eat less for dinner. Eating too much dinner is easy to digest, leading to fat accumulation in the abdomen, which will naturally grow into a small belly over time.
Eat as little as possible at dinner every day, and have a light diet. If you are not hungry, you can only eat 30% to 50% full. Two hours after a meal, you might as well have some yogurt to help digestion. Eating less at dinner is definitely the first prerequisite to help you get rid of your big belly.
Sleep reasonably, don't always stay up late, and work and rest on time. In short, eating less and exercising more and living a regular life are all good ways to lose weight.
