A study by researchers at the University of California, Irvine, published in Cell Metabolism, shows that foods which are rich in a “good” monounsaturated fat called oleic acid — namely avocadoes, olive oil, and nuts — actually curb hunger pangs.
How? The oleic acid triggers production of a fat-derived hormone called oleoylethanolamide (OEA): this carries a hunger-curtailing message to your brain where it activates a circuit that sends a message to your stomach that it is full and therefore, indirectly, may help reduce your body weight.
The researchers say their findings mean that OEA could form the basis of new anti-obesity drugs. In the meantime, up your intake of these foods to quiet your hunger response naturally.
