1.Each meal should be moderate Some people joke that a person's life can eat food, it is a fixed number, is 60 tons.

If you can control what daily food intake, eat Qi Bafen , then you 'll eat more than the average person years or even decades ...... It may seem ridicule meaning, but thin aftertaste , but also some truth.
