Gut hormones are released before and after a meal to initiate and terminate food intake. The authors measured gut hormone release after a palatable tasty meal before and after rats exercised in running wheels. In rats with a lot of running wheel experience, consuming a tasty meal led to increased blood levels of an inhibitory feeding hormone, amylin. After the meal, the same rats showed a more rapid rebound of a stimulatory feeding hormone, ghrelin. The authors also demonstrated that compared to sedentary control rats, exercise-experienced rats decrease their food intake more robustly after treatment with CCK, a gut hormone that limits meal size.
