Yes, but it will cause malnutrition. I gained a little weight for a while, that is, I was vegetarian and ate porridge instead of dinner, but I always felt a little dizzy after I lost weight. In fact, if you lose weight, you should stick to the flat support for ten minutes every day, and you can see the effect in about a month. It's a little slow, but I'm quite suitable. In fact, you can eat normally, but make sure you don't eat after 8 pm. If possible, don't eat meat and staple food for dinner.
