Medial neurons utilize NPY peptides as neurotransmitters to stimulate appetite, and lateral neurons utilize POMC/CART to inhibit appetite. [2] NPY and POMC/CART neurons are sensitive to peripheral hormones such as leptin and insulin. [4] POMC/CART neurons also secrete melanocyte-stimulating hormone, which suppresses appetite.

Appetite suppressants can impact several systems in your body, Keatley says. “Some may alter hunger hormones like ghrelin, which signals hunger; leptin, which signals fullness; ...
New research suggests high-intensity exercise could help curb feelings of hunger, particularly in women, by decreasing levels of ghrelin, the "hunger hormone." High-Intensity Exercise Works Like ...
Ghrelin, leptin, and peptide YY are among the hormones involved in appetite control. Additionally, neurotransmitters such as serotonin and dopamine in the central nervous system contribute significantly to the regulation of food intake. By contrast, an appetite stimulant is referred to as orexigenic.
