Satiety
Also known as Satiation - Fullness
The feeling of being full. Driven by GLP-1, PYY, protein, fiber, and sleep - not willpower.
Satiety is the signal to stop eating, driven by gut hormones (GLP-1, PYY, CCK, leptin), meal composition, and sleep architecture. Protein at 30-40 g per meal boosts satiety more than any other macro; soluble fiber at 8-12 g per meal adds a second lever. Sleep under six hours suppresses leptin ~15% and raises ghrelin ~28%, which is why sleep-deprived weeks always feel hungrier. GLP-1 medications amplify satiety by extending the natural post-meal signal - that's the whole mechanism. See the GLP-1 eligibility guide for what that actually requires.
