Eating carbohydrates turns off NPY production through its effect on which brain chemical?

The correct response to the question highlights the role of serotonin in the regulation of neuropeptide Y (NPY) production in the brain. When carbohydrates are consumed, the body experiences a surge in insulin, which facilitates the uptake of glucose into cells and stimulates the production of serotonin in the brain. Elevated serotonin levels are associated with feelings of well-being and satiety, which in turn inhibit the release of NPY.

NPY is a neuropeptide that is involved in stimulating appetite and promoting food intake. When serotonin levels rise due to carbohydrate consumption, it serves to reduce the appetite-stimulating effects of NPY, helping to regulate food intake and maintain energy balance. Thus, the interplay between carbohydrates and serotonin is crucial in understanding appetite control and the mechanisms of satiety.

Other options do not play a significant role in this specific mechanism related to carbohydrate consumption and NPY production.
