Wait until you're hungry before eating, okay?

　　Eat when you are hungry

　　Many people forget to eat when they are busy, thinking that they will eat when they are hungry. In fact, this approach is wrong.

　　Food only stays in the stomach for 4-5 hours. When a person feels hungry, the stomach has been emptied, and the gastric mucosa will be "self-digested" by gastric juice, which can easily cause gastritis and peptic ulcer.
