Why are you hungry after taking a shit?

Well, I'm still a little self-aware ~ just kidding. My opinion is that the digestive tract is integrated. When defecating, the jejunum is discharged, and the stomach is peristalsis. After emptying, there will be signals such as' the intestine is empty', and so will the stomach. When the two signals are superimposed, they reach the threshold of hunger, so they are hungry. . .
