Question

Quizplus · Accepted Answer

There are two sources of satiety signals that act to stop a meal: stretch receptors in the stomach and hormones secreted by the gastrointestinal tract. These signals work together to regulate meal size and duration. Ghrelin is actually an appetite-stimulating hormone produced by the stomach, so it does not represent a short-term satiety signal. Insulin can play a role in long-term satiety as it helps regulate glucose levels, but it is not the only signal involved in this process. Short-term satiety signals, such as cholecystokinin, are secreted by the gastrointestinal tract, not adipose tissue.
