No matter what kind of weight loss products are bad for your health, I suggest you lose weight healthily, such as eating breakfast on time every morning, eating beef (nourishing qi and blood), fish, shrimp and chicken (without skin) at noon, and eating less staple food. It is best to eat fruit at night. In this way, when you lose weight quickly at first, you lose one catty a day, and then lose another catty in a few days, so you don't feel weak when you lose weight. Besides, you will get thinner and thinner.
