How Dietary Proteins and Fats Trigger the Release of Digestion-Controlling CCK
Intraluminal peptide releasing factors triggered by dietary proteins and fats are key regulators of CCK secretion, coordinating digestion and signaling fullness.
Quick Facts
What This Study Found
Intraluminal peptide factors, released in response to dietary proteins and fats, are key regulators of CCK secretion that coordinate digestion.
Key Numbers
How They Did This
Narrative review of published research on CCK secretion mechanisms, luminal releasing factors, and their roles in digestive physiology.
Why This Research Matters
CCK controls how we digest food. Understanding its release mechanisms is important for treating digestive disorders and for weight management, since CCK also signals fullness to the brain.
The Bigger Picture
CCK is one of the body's main "I'm full" signals. Understanding what triggers its release could help develop dietary or pharmaceutical approaches to control appetite and improve digestion.
What This Study Doesn't Tell Us
Narrative review from 1995. Some mechanisms have been further clarified since publication. The luminal releasing factors were not fully characterized at the time.
Questions This Raises
- ?Could CCK-releasing dietary strategies help with weight management?
- ?Are CCK-releasing factors altered in digestive disorders?
Trust & Context
- Key Stat:
- Luminal peptide triggers Specific peptide factors released during protein/fat digestion are the key signals triggering CCK secretion
- Evidence Grade:
- Moderate — comprehensive review of CCK release mechanisms as of 1995.
- Study Age:
- Published in 1995 (31 years ago). CCK release mechanisms have been further characterized; the basic principles remain valid.

What do these levels mean? →Frequently Asked Questions
What is CCK?
Cholecystokinin is a gut hormone released when you eat protein and fat. It triggers gallbladder contraction, pancreatic enzyme release, and sends a "full" signal to the brain to stop eating.
Why does protein make you feel full?
Protein digestion releases peptide factors in the gut that strongly trigger CCK release. CCK then signals the brain that you've eaten enough, creating satiety. This is why high-protein meals are more filling.
