Fiber, GLP-1 and your body's natural fullness signals

GLP-1 is a hormone released by cells in your gut after you eat. It slows stomach emptying and tells your brain you've had enough.

Where fiber comes in

When gut bacteria ferment fiber, they produce short-chain fatty acids, which can stimulate the release of GLP-1 and other satiety hormones. It's a natural, gentle effect — not the same as medication.

Habits that support it

Protein and fiber at each meal, eating slowly, and steady sleep all support appetite regulation over time.
