Ghrelin is an orexigenic gastric hormone. Plasma ghrelin was determined together with hunger and satiety ratings and with insulin after the ingestion of satiating quantities of carbohydrate-, fat-, protein-, fruit-, and vegetable-rich meals. Ghrelin release depends on the ingested macronutrients: after carbohydrate, ghrelin decreased, whereas fat and protein ingestion significantly increased ghrelin levels. Considering all test meals, no correlation existed between changes of ghrelin levels and satiety ratings, therefore ghrelin is most likely not a major regulator of acute food intake, whereas a significant inverse relationship was observed between plasma ghrelin and insulin levels.
