3.Cholekystokinin

CATEGORY:

•Hormone

DEFINITION:

•Cholekystokinin is a Peptide Hormone of the gastrointestinal system responsible for stimulating the digestion of fat and protein

FUNCTION:

•CCK mediates a number of physiological processes, including digestion and satiety

•Acts as a hunger suppressant...

-Mechanism is a decrease in the rate of gastric emptying (digestion)

-CCK receptors distributed widely throughout the CNS

ACTION:

•Presence of Fatty Acids and/or certain Amino Acids are the greatest stimulator of CCK release

•Works in opposition to Ghrelin

•Delays Gastric Emptying of all contents

FACTS:

•Also known as Pancreozymin

•Leptin Resistance reduces effectiveness of CCK and its role of satiety in consuming Proteins & Carbs

MANIPULATION:

•CCK's satiating affect of Protein & Fat consumption leads to suggestion of eating Protein & Fats with every meal to increase a sense of fullness

•The more CCK there is the sooner a sense of fullness, the less food is consumed

DIETING:

•Fibre also encourages and sustains the elevation of CCK in the blood

RELATED TO:

•Ghrelin

•Leptin

•Protein & Fats (ingested)
