Pharmacologically, drugs can be divided into the following categories: drugs that enhance energy consumption; Drugs that suppress appetite; Drugs that prevent digestion and absorption; Drugs that affect fat metabolism. For some obese patients with endocrine disorders and abnormal metabolism, the role of drugs in losing weight should be affirmed. But for most simple obese people, drug weight loss is not the main means of weight loss, but only as an auxiliary means of exercise weight loss and diet weight loss. Diet pills not only affect the body's absorption of heat energy substances, but also affect the body's absorption and utilization of other nutrients, and may have other adverse effects on the body. Might as well not eat.
