First of all, you should have a comprehensive understanding of your physical fitness (such as whether you will have adverse reactions to any drugs, whether you have other diseases, etc.). If you don't know the situation, consult experts or professionals, and don't jump to conclusions. Generally speaking, the following questions should be paid attention to when choosing healthy weight-loss products: 1. Packaging: See if the formula contains sex hormones. Products containing hormones can cause endocrine disorders and lead to other complications. 2. Mechanism: See clearly whether there is any weight loss mechanism of drugs in the instructions to determine safety and effectiveness. 3. Look at the type of obesity: Weight loss products are generally effective for simple obesity, obesity that can't be controlled by diet and exercise, and poor for hereditary obesity. If you can't determine the type of obesity, you can consult a doctor or medical professional in the local weight loss center to make a suitable weight loss plan before choosing the right weight loss product. 4. Batch number: Pay attention to the approval number of the product, whether it is approved by the authoritative presiding organ of the state, such as the batch number of National Medicine Zhunzi. Generally, the audit requirements of the national presiding organ are stricter than those of the local examination and approval authorities, and the products that can pass the examination and approval of the national presiding organ are safe and reliable in quality.
