Not only can extreme obesity take 10 years off your life, it could also be prematurely aging your brain. According to a new study published in Human Brain Mapping, the brains of obese people look 16 years older than those of lean people, due to eight percent less brain tissue on average. The brains of individuals classified as "overweight" appear eight years older than those of normal-weight people.
Though the study was rather small — 94 brain scans of subjects in their 70s — researchers concluded that the loss of brain tissue due to weight problems could put patients at higher risk of Alzheimer's. According to study author and UCLA neurology professor Paul Thompson, "you can greatly reduce your risk for Alzheimer's, if you can eat healthily and keep your weight under control." So shape up your body, and the mind will follow.
Every day, it seems, we read about another health risk tied to obesity, but this is one of the most surprising I've come across. Does this shock you?
