Especially hungry

The energy of a person's physiological activity is directly derived from blood glucose, which is derived from nutrients obtained by digestive organs such as the small intestine from food. The reason why a person is hungry is that the blood glucose concentration in the blood decreases, and then there is a normal physiological response. At this time, you should add food (ie, eat). If you do not add food immediately at this time, a little longer, the physiological response will promote the breakdown of liver glycogen (from the cell lipolysis, which is completed by bile). At this time, people will feel hungry, and they will not be hungry.
