If you don't go on a diet, you should take more exercise. If you don't diet and exercise. It is best to drink chitin half an hour before eating a big meal.
About chitin: the function is to prevent fat absorption, increase satiety and eat occasionally. If 1 day eats three meals a day, it is recommended not to exceed 2 months. Although there are no side effects, it will prevent the excretion of vitamins carried in fat and lead to the lack of fat-soluble vitamins (vitamins A, D, E and K). So you see, fat is also important. It is best to supplement fat-soluble vitamins and fatty acids during this period. So it doesn't matter.
See you also mentioned that protein and protein are less likely to be converted into human fat than fat and sugar. And it is true that protein will damage the heart and muscles (muscles are an important condition for consuming fat, and the calories consumed by people every day mainly come from human muscles). Protein actually increases satiety and easily becomes fat. You should eat some. Again, eating too much will definitely make you fat. Just pay attention to moderation.
I made the above by myself. Take a closer look. It's all my experience collected and summarized everywhere. I have been an expert for a long time. I hope it helps you.
