Ghrelin is known to be associated with both the endocrine and nervous systems and is also known to increase food intake. It is an appetite-stimulating hormone that is primarily released by the stomach in response to fasting or low-calorie intake. Ghrelin levels are highest before meals and decrease after eating. While it does have some role in regulating feelings of satiety, it is primarily associated with stimulating hunger. High levels in the brain have not been shown to cause refusal to eat in laboratory rats, but rather a decrease in food intake.
