Being overweight reduces risk of dementia.... According to BBC Reporting

Here's the link: http://www.bbc.co.uk/news/health-32233571

To quote:

"The team at Oxon Epidemiology and the London School of Hygiene and Tropical Medicine analysed medical records from 1,958,191 people aged 55, on average, for up to two decades.

Their most conservative analysis showed underweight people had a 39% greater risk of dementia compared with being a healthy weight.

But those who were overweight had an 18% reduction in dementia - and the figure was 24% for the obese."

Now given the discussions we've had relating to LCHF and Statins, one wonders whether there is an increase in certain fatty acids and enzymes when overweight, that links to brain health. CoQ10 anyone?

Is being overweight really a protective factor?
The key question that needs to be asked is: "What preceded the low body weight in those that developed dementia during the study period?" The other question that arises from the study is what the results would be if the study period were to be extended by up to another 20 years? Would those that were obese within the 1990s maintain a low risk of dementia or would they be shown to have a much higher risk 20 years further down the line?

Until these questions are answered, they key message for health remains that maintaining a healthy weight and following an active lifestyle is the best option for reducing your risk of dementia in older age.

The guardian begs to differ:

Although Alzheimers is not the same as dementia.

They were talking about middle aged people with BMIs smaller 20 or smaller. I'm speculating that this very low BMI reflects a low muscle mass, which could give a poor metabolism.

who know and they haven't done a double blind study

Tricky one to do a double blind study on really. This is really a meta-study rather than a specific one. It does have a huge sample size and long duration so should allow for better normalisation.
