Blame your brain for sabotaging your efforts to get back on track after splurging on an extra scoop of ice cream or that second burger during Friday night’s football game.
Findings from a new UT Southwestern Medical Center study suggest that fat from certain foods we eat makes its way to the brain. Once there, the fat molecules cause the brain to send messages to the body’s cells, warning them to ignore the appetite-suppressing signals from leptin and insulin, hormones involved in weight regulation.
“What we’ve shown in this study is that someone’s entire brain chemistry can change in a very short period of time. Our findings suggest that when you eat something high in fat, your brain gets ‘hit’ with the fatty acids, and you become resistant to insulin and leptin,” Dr. Clegg said. “Since you’re not being told by the brain to stop eating, you overeat.”
