You've heard "a minute on the lips, years on the hips," or some variation. But did it make you put down that frosted butter cookie?
No? OK, here's another bit of research to snack on: After humans and rodents eat a high-fat diet, their brains begin to show evidence of injuries in just 24 hours. If they keep eating that yummy fatty stuff continuously, the area of their brains that regulates weight -- the hypothalamus -- will show evidence of serious inflammation and structural damage.
