Don't be greedy, don't skip meals, and don't overeat after meals. Be responsible for your health.
There is a saying that "eat radish in winter and ginger in summer". Personally, I think it's better to go to a Chinese medicine shop to buy some radish seeds and fry them, just like melon seeds. Eating them when you have nothing to do is effective and healthy. After all, it is Chinese herbal medicine, which is much better than choosing diet pills at random.
Don't eat breakfast all day, and don't eat lunch and dinner. This will lead to malnutrition. What about stomachache?
Being fat means you can't detoxify. If you eat too much, you can eat more things to promote digestion. If you have nothing to do, you can soak the hawthorn in water to drink appetizers, or you can fry it with radish seed oil, which is especially easy to digest.
There is also proper exercise, not paying attention to a certain amount of exercise, but persistence and self-discipline.
