Oil discharge is a false concept. Fat can't be discharged directly, but can only be metabolized by consuming calories. Diet pills known as oil displacement are generally laxatives, which can quickly dehydrate the body (you think it is fat). After a single hydration, the weight will return to normal, which will lead to gastroenteritis after long-term use, and constipation may occur after stopping taking the medicine. So do you think this thing can lose weight?
