A new study finds obese people have 8 percent less brain tissue than normal-weight individuals. Their brains look 16 years older than the brains of lean individuals, researchers said today. Those classified as overweight have 4 percent less brain tissue and their brains appear to have aged prematurely by 8 years.
"That's a big loss of tissue and it depletes your cognitive reserves, putting you at much greater risk of Alzheimer's and other diseases that attack the brain," said Paul Thompson (ACLU). "But you can greatly reduce your risk for Alzheimer's, if you can eat healthily and keep your weight under control."
The findings are detailed in the online edition of the journal Human Brain Mapping.
More than 300 million worldwide are now classified as obese, according to the World Health Organization. Another billion are overweight. The main cause, experts say: bad diet, including an increased reliance on highly processed foods.
Obesity is measured by body mass index (BMI), defined as the weight in kilograms divided by the square of the height in meters. A BMI over 25 is defined as overweight, and a BMI of over 30 as obese.
