Rat Study Finds that Fat Triggers the Munchies

Digital Vision/Thinkstock(IRVINE, Calif.) -- New research suggests that fatty foods give people a high that may contribute insatiable food cravings.

The study was conducted on rats by researchers at the University of California, Irvine School of Medicine. The rats were given various liquids containing fat, sugar, or protein. Scientists then found that the fatty liquid triggered endocannabinoids, naturally-produced substances which control the appetite.

Endocannabinoid research could lead to medication that helps regulate food cravings.

The study will be published in an upcoming issue of the Proceedings of the National Academy of Sciences.
