I was introduced to this instrument a few days ago. I don't know exactly how to lose weight, but I hear it's very useful. However, I dare not try for two reasons. I'm afraid it's harmful to my health, and it won't work.
I'm also losing weight now. I'm eating a product, then I control my diet and exercise more. It has already started to work. It feels good. You can add me QQ: 407346492 if you want to know.
