As a long-term signal of satiety, which hormone is produced by adipose (fat) tissue to suppress appetite over time?

Question

BlackTom AI · Accepted Answer

To tackle the question, I will evaluate what each hormone does in relation to satiety and adipose tissue signals.
Option a: Ghrelin. This hormone is known as the hunger hormone, primarily produced by the stomach, and it stimulates appetite rather than suppressing it. It acts acutely to increase food intake, especially before meals, so it does not represent a long-term adipose-derived satiety signal.
Option b: PYY. Peptide YY is released by the gut in response to feeding and can reduce appetite, but it is not produced by adipose tissue. Its role is more about signaling after a meal in the gastrointestinal tract rather than serving as a long-term signal of fat stores.
Option c: CCK. Cholecystokinin is another gut-derived hormone that promotes satiety by signaling fullness after a meal, primarily from the small intestine and pancreas. It is not produced by adipose tissue and does not convey long-term energy status from fat stores.
Option d: Leptin. This hormone is produced by adipose tissue and acts as a long-term regulator of energy balance. Leptin levels reflect fat mass and signal the brain to reduce appetite and increase energy expenditure in proportion to adipose stores, thereby serving as a sustained signal of satiety over time.
In summary, while ghrelin, PYY, and CCK are involved in acute or meal-related appetite regulation and are not adipose-derived long-term signals, leptin uniquely fulfills the role of a fat-derived hormone that suppresses appetite over longer periods as fat stores change.
