I know that drinking Pu 'er tea can lose weight, and I have been drinking it. It still has a certain effect, although it is not so obvious, but it is also very safe. I used to drink diet tea and have diarrhea, and I never dared to take any diet pills, no matter how he introduced me. I suggest that you can also drink Pu 'er tea to lose weight. If that product is extracted from Pu 'er tea, it should be safe. If you are in a hurry to lose weight, you can try. But be sure to find out if it comes from Pu 'er tea. Good luck and lose weight together.
