Lard Lesson: Why Fat Lubricates Your Appetite

Saturated fat dulls the brain’s response to key appetite hormones, an effect useful in our evolutionary past during times of scarcity, but not so much in a well-fed society.

As a result of the hormone resistance, a meal high in saturated fat can crank up our appetite well after dessert. “Taking time off from a healthy diet to eat most fast foods may have consequences that last for some days, even after one resumes the healthy diet,” says University of Cincinnati behavioral neuroscientist Stephen Benoit, who led the study. He believes the findings are likely to apply to humans, too.
