Do you know what is the fastest and most effective way to lose weight? I recommend you drink green tea twice a day 20 minutes after each meal (it can be breakfast and lunch). In this way, he will help you burn fat and accelerate metabolism.
I have done it, and I still do it, it has given me so many good results that I am very satisfied. But yes, I recommend you also investigate, since not everyone can drink it (for example diabetic people).
But do not forget to exercise!
