The Vagus Nerve Amplifies Ghrelin's Suppression After Eating Fat

Vagal stimulation exaggerated the normal fall in ghrelin after oral fat intake, revealing the vagus nerve as an amplifier of the ghrelin-suppressing satiety signal from dietary fat.

What This Study Found

Vagal stimulation amplified the inhibitory ghrelin response to oral fat in a human/animal model, demonstrating the vagus nerve acts as a gain controller for fat-induced ghrelin suppression — the gut-brain communication amplifying satiety.
