I heard it for the first time, but I suggest not to use it for fear of side effects.

Losing weight is actually very simple, such as not eating.

On the basis of controlling calories and balancing nutrition

The calorie intake per day should not exceed 1500 calories. It is normal to eat for 5 days, and the younger one should eat for 2 days.

You can also do some small-scale exercise, and the effect is better.
