I recall on an ask reddit a group of gastroenterologists were answering questions. One thing that stood out was they said "let your stomach rumble it's a necessary part of gut health".

Fasting would help initiate that, but I think so many people these days never stop eating long enough for their stomach to rumble.

I have also read that our gut doesn't like being in constant operation. Our ancestors didn't have access to food 24/7 and it makes sense our bodies adapted to take advantage of this by entering a self-cleaning state during long periods without consumption.
