Oleoylethanolamide (OEA) works to activate something called PPAR and simultaneously ramps up fat-burning and decreases fat storage. When you eat, OEA levels increase and your appetite decreases when the sensory nerves that link to your brain tell it that you're full. PPAR-α is a group of ligand-activated nuclear receptor that involved in the gene expression of lipid metabolism and energyhomeostasis pathways.
