Jorge, who just finished a large dinner an hour before, is offered a slice of pizza by his roommate. jorge says, "no . i'm not hungry." the digestive track hormone is sending the "i am not hungry" signal to jorge's brain.

Leptin

Explanation:

Leptin is the satiety hormone. It is through him that we realize that our stomach is full and we do not feel like eating more food. Leptin is produced by adipose tissue, the higher the body fat, the greater the amount of leptin. Finally, when their levels are high, food intake decreases and when their levels are low, they induce excess food consumption.

Jeorge did not want to eat the piece of pizza that was offered to him because he had already been fed. His stomach was full and leptin indicated he was satiated and didn't need to eat that pizza.
