Today's "Well, duh" story:
If you've ever wondered why it's hard to stay on a diet, consider this observation from Ralph DiLeone, a brain scientist at Yale University: "The motivation to take cocaine in the case of a drug addict is probably engaging similar circuits that the motivation to eat is in a hungry person."
That's what brain scientists have concluded after comparing studies of overeating with studies of drug addiction, DiLeone says.
They've also found that, at least in animals, sweet or fatty foods can act a lot like a drug in the brain, he says.
Why do you think they call it food, kid?
