More Weight = Less Brain?

If you’re looking for one more reason to stay in shape, we have found it. According to a study published in the December 2010 issue of Brain Research, becoming overweight or obese can shrink your gray matter. That’s the finding of Antonio Convit of the NYU School of Medicine, who used an MRI to compare the brains of 44 obese people with 19 lean people. The obese subjects showed more water in the amygdala, a section of the brain that affects eating behavior, and smaller orbitofrontal cortices, which affect impulse control. Convit thinks overeating may increase the risk of future overeating. Seems it also may increase the risk of being called “pinhead.” (Sorry, we seem to be big on nicknames at the moment.)
