The diet pills sold by Taobao are definitely effective, but they also have side effects. Its side effect is that you lose water all over your body, and then you will have nausea and retching, and the whole person is likely to faint. It is useful because it is possible to lose weight, but your water is lost. As long as we usually replenish water, we are still obese. It is impossible to say that if we lose water, you won't gain weight. Fat is fat. I can say for sure that so far there is no medicine that can directly reduce your fat. Only by strengthening her metabolism through exercise can she lose weight.
