Cholecystokinin (CKK)

What is Cholecystokinin (CKK)

Cholecystokinin (CKK) is a kind of naturally occurring appetite-suppressant chemical. As food is digested and your body cells are ‘fed’, CKK is released and your brain tells you – stop eating!

However, researchers believe that the CKK appetite mechanism is faulty in some people – possibly due to excessive dieting or binge eating/purging. This can cause the person to stop eating too soon, or overeat.

Weight loss drug companies are developing Cholecystokinin-booster supplements to reduce appetite in those who suffer from severe obesity. How effective these CKK boosters are remains to be seen.
