Many diet pills, tea, weight loss coffee, massage, catgut embedding, etc. What they show you is the change of weight in a short time, not the change of body fat. How do you say this sentence? It is to let you excrete a lot of body fluids in a short time, make you have the illusion and deceive yourself to lose weight, which is actually caused by the loss of body fluids. In fact, there is no shortage of fat in the body. On the contrary, after stopping using similar drugs, the body's self-repair function begins to play a role, allowing you to quickly replenish water and food. This will lead to the soaring weight and body fat in a short time, which is often called rebound. This rebound is very heavy for the body and mind. People still don't do experiments with their own bodies.
