Sci picked this paper today partially because it was handed to her on a platter by the fantastic Dr. Pal, and partially because today she is SO HUNGRY. She’s had a TON of food already today, and is still entirely ravenous. Maybe it was looking at this paper too long.
As I’m sure most of y’all out there are aware, obesity is a problem in the US. No one is sure whether it’s due to increased portion size, increased availability, decreased physical activity, changes in gut bacteria, issues with our behavioral approaches to food, or all of the above. But scientists have been working for a while not only to look at the effects of overeating and obesity, but also to look at what CAUSES these things in the brain and body. And today we present a paper on an interesting piece of this puzzle, one that Sci has had a good deal of interest in: the idea of overeating as an addiction-like phenomenon.
