It doesn't work. I still feel like going to the toilet and having diarrhea. I am useless. I used it last year. I lost a lot of weight after using another one to cope with the change of diet. About 2 months, it looks like 13J. What I saw: The method in Zhou Xinlei's diet diary is to change yourself patiently, which is also a kind of exercise. For example, my menu today, breakfast: 1 egg pancake (without crispness), 200ml pure milk, Chinese food: 100g gold and silver rice (corn grits, standard rice), fried chicken with black fungus and bamboo shoots, etc. Dinner: one corn, 4 pieces of garlic, rattan vegetables, steamed fish. Actually, it's rich in recipes. If you are hungry and thin just because you don't eat less, will you continue to eat such terrible food in the future? Therefore, the diet should be moderate, rich and nutritious, but not too many calories. You can look at the diary in detail, I hope it will help you.
