Neuropeptide Y is known to increase appetite and promote weight gain. Injecting the rat with it would likely increase its food intake and help it gain weight. Lesioning the lateral hypothalamus, on the other hand, would decrease appetite and food intake. Electrically stimulating the ventromedial hypothalamus could also decrease appetite and cause weight loss. Injecting the rat with CCK would lead to feelings of fullness and decreased appetite, making it difficult for the rat to eat enough to gain weight.
