Fat Guys Dumb
But maybe not fat women. Actually, this is about mice: Chiou Lih-Chu provided a high-fat or normal diet to her subject animals, then examined their brains at what would be, for a person, middle age. Male mice who’d lived on the high-fat diet showed far less responsiveness in the hippocampus than the lower-fat controls (the hippocampus is key to the ability to learn). Correspondingly, the high-fat males were slower to learn new behaviors. Unexpectedly, females on the high-fat diet were similar to the lower-fat females and the lower-fat males.
