I saw an interesting study describing the effect of obesity on brain function. In short:
Of course, as new as this is, there’ll be plenty of arguing over whether it’s valid, and whether the conclusions are being interpreted correctly. But what if it’s right? What if obese people tend to be less intelligent than the non-obese? What does this mean for the treatment of obesity in America?
As an aside, the study did not find a link between obesity and lowered mental function in women. Whether that’s deep and meaningful or a fluke of this study remains to be seen.
