     This is not a diet. It's a simple way to lose weight And you don't even have to give up the food you love

or join a gym. You just follow some habits that thin people have. Keep them, and you'll become thin.

      When you wake up in the morning, sit up slowly without using your hands. With legs straight out, bend

(弯曲) forward until you feel sore in your back. It will burn about 10 calories (热量单位, 卡路里).

feel fuller, so you'll eat less when the main food comes.
