A friend of mine bought powder before, and I advised her not to buy it. She doesn't believe it. She hasn't lost a pound after eating more than 300 yuan. Because she was hungry after eating for a while and ate a lot a day. Ha ha. Later, I told her to eat less, eat more vegetables and drink porridge at night. I lost ten pounds in a month.
So don't trust those diet products. If you want to lose weight, you should exercise more to burn calories in your body, or you can eat less or not exercise. There is no shortcut.
