Researchers at the Cambridge Centre for Ageing and Neuroscience, examining the loss of white matter in the brains of lean and overweight persons, have discovered that the brains of overweight people tend to resemble those of leaner people who are roughly ten years older. These differences are more pronounced from middle-age onwards.
“Those in the overweight group had much less white matter than their thinner counterparts”.
