Your gut has its own nerve network and gets on with the job whether you attend to it or not.

What it means

Nerves in the walls of the digestive tract release signals that speed up or slow down the muscular squeeze pushing food along, and much of that traffic never involves the brain at all. Hormones from cells lining the stomach and small intestine coordinate the rest, telling the body when to release digestive juices and reporting hunger and fullness upward. The system runs while you sleep, and it runs on its own signals.

The claim comes from NIDDK.
