Diet pills actually don't help to lose weight, and some only have obvious effects in a short time and are easy to rebound; What's more, some unscrupulous merchants sell drugs that are harmful to health. These goods can't get marketing permission and can't apply for patents. Manufacturers can only sell WeChat business on WeChat. This sales method does not need the above two or other certificates, and there is no way to apply for a refund or a series of actions to protect consumers' rights and interests if there are problems with the drugs. I don't usually shop on WeChat because it's unreliable. If the subjects need to lose weight, it is recommended not to use this method, just control their diet but be nutritious on weekdays; Exercise more; Eat less supper and go out to eat less. The food outside is generally gutter oil, which is easy to get fat and harmful. Don't overeat and eat emotionally; Eat more coarse grains, vegetables and fruits. It is recommended to eat more broccoli and celery. Scientific proof is helpful to lose weight, but we should also control the amount.

I hope the answer can be helpful to the subject and I wish you good health!
