Many people lose weight in this way to reduce their appetite. If they eat less, they will naturally at least not gain weight. This kind of words is less harmful to the body and can be accepted.
2, inhibit gastrointestinal function, food digestion is not sufficient.
To put it bluntly, the stomach and intestines are not allowed to work normally, and the food is directly excreted without being fully digested. This kind of thing is the last use. After a long time, your stomach will never get better. Girls don't grow up. You'll know when you get old. How painful it is to have a bad stomach After 40, if you are not fat, you will lose weight. That kind of thinness is a kind of shriveled thinness, which is not as good as being fat.
3, add stimulants, have a strong desire to exercise, increase perspiration.
This kind also has a bad place, that is, these things diuretic and take away a lot of body water. You will obviously feel thinner, but half of it is your fat and half is the water in your body. It's harmful to your health anyway.
