Post-Ingestive Satiety Signal
Post-ingestive satiety signals come from nutrients in the gut and blood—protein and fiber sustain fullness longer than ultra-processed calorie hits.
Post-ingestive satiety signals arise after nutrients hit the gut and blood—peptide YY, GLP-1, cholecystokinin, and glucose stability—telling the brain to reduce appetite for hours. Protein, fiber, and balanced meals sustain these signals; ultra-processed hits can spike reward while failing to hold fullness.
Liquid calories often weaken post-ingestive feedback.
Common questions
-
Why am I hungry again after fast food?
Hyper-palatable low-fiber meals can spike reward without durable post-ingestive hormone support. Adding protein, produce, and whole-food volume usually extends the gap to the next meal.
