Being overweight 'linked to dementia'

More benefits to being fat.

Middle aged people who are overweight but not obese, are 71% more likely to develop dementia than those with a normal weight, according to research.

Previous studies have indicated a link between obesity and dementia.

But a study 8,534 of Swedish twins, in the journal Neurology, suggests just being overweight is also a risk factor.

About one out of every 20 people above the age of the 65 has dementia. The Alzheimer's Society said a healthy lifestyle could reduce the risk.

Those with a body mass index (BMI) - which measures weight relative to height - greater than 30, who are classified as obese, were 288% more likely to develop dementia than those with a BMI between 20 and 25, according to the study.

The clinically overweight, who have a BMI between 25 and 30, were 71% more likely.

Kudos, fatsos.
