It may be true that carrying a few extra pounds isn’t the end of the world. But that doesn’t mean fat is innocuous: Tara Parker-Pope has an article about some very interesting experiments in rats that show a clear and rapid effect of eating fatty foods.
[T]he new research shows how indulging in fatty foods over the course of a few days can affect the brain and body long before the extra pounds show up…
“We expected to see changes, but maybe not so dramatic and not in such a short space of time,’’ said Andrew Murray, the study’s lead author and a lecturer in physiology at Cambridge University in Britain. “It was really striking how quickly these effects happened.’’
The same group has done similar experiments on people, though the results have yet to be published. It’s an interesting article, definitely worth a read.
