Hunger hormones I would like to briefly mention some hormones (we will call hunger hormones for simplicities sake) that basically tell your brain how much your eating and what your body fat levels are. These hormones include insulin,leptin,ghrelin,peptide YY, neuropeptide Y (NPY), cortico-tropin releasing hormone (CRH) and, cholecystokinin (CCK). All of these hormones respond to food intake and send messages to your brain to tell you what is going on. Numerous regions of the brain are involved with the regulation of food intake and energy balance. For our purposes we will only focus on the regions that are considered most important in regards to the hunger hormones. The arcuate nucleus (ARC), which is readily accessible to circulating hormones, is considered the primary hypothalamic site of food-intake regulation. Two main neuronal subsets located in the ARC which is readily accessible to circulating hormones, is considered the primary hypothalamic site of food-intake regulation. Two main neuronal subsets located in the ARC are responsible for relaying information about energy balance from peripheral hormones to various regions of the brain and are classified as either orexigenic (appetite stimulating) or anorexigenic (appetite suppressing). Neurons expressing neuropeptide Y (NPY) and agouti-related protein (AGRP) are orexigenic, while those expressing proopiomelanocortin (POMC) and cocaine- and amphetamine regulated transcript (CART) are anorexigenic.
