More on brain changes in obesity:

An April 2011 Nature article by French researchers demonstrated that diet-induced obesity in miniature pigs leads to decreased activation of the prefrontal cortex, a brain region used for “inhibition of inappropriate behavior, satiety, and meal termination.”  The brain activation was determined by regional blood flow as measured by SPECT imaging.

Like the pigs, obese men also show reduced activation of their prefrontal cortex, and it’s not known whether these brain changes cause obesity, or obesity causes the brain changes. Continue reading
