Gastric Stretch Satiety Signal
The gastric stretch satiety signal uses stomach distension from bulky, lower-density foods to tell the brain you have eaten enough—even when calories are moderate.
The gastric stretch satiety signal comes from stomach distension—fiber, water-rich vegetables, and broth soups trigger vagal nerves that tell the brain you have eaten enough volume. Calorie-dense bites without bulk can hit energy targets while stretch stays low, leaving hunger soon after.
Food volume eating and half-plate produce habits lean on this pathway without extreme restriction.
Common questions
-
Can you feel full on fewer calories with stretch?
Yes—volume from vegetables, fruit, and lean protein increases stretch per calorie. Dense fats and sweets add calories without much distension, so hunger can return quickly.
