Appetite Neurotransmitters

Meaning

Appetite neurotransmitters are chemical messengers within the central and peripheral nervous systems that regulate feelings of hunger, satiety, and overall food intake behavior. These crucial signaling molecules integrate metabolic status, gut-derived signals, and cognitive processes to maintain energy homeostasis. Key examples include neuropeptide Y (NPY) and agouti-related peptide (AgRP) which stimulate appetite, alongside serotonin and cocaine- and amphetamine-regulated transcript (CART) which promote satiety. Their precise balance dictates feeding patterns and body weight regulation.
