Being overweight is not just bad for waistlines but for brains too, say researchers who have linked obesity to declining mental performance.

Experts are not sure why this might be, but say metabolic changes such as high blood sugar and raised cholesterol are likely to be involved.

The work, published in Neurology, tracked the health of more than 6,000 Britons. The participants, who were aged between 35 and 55, took tests on memory and other cognitive skills three times over a 10-year period.

People who were both obese and who had unhealthy metabolic changes showed a much faster decline on their cognitive test scores compared to others in the study.

將過胖與心智表現衰退連結的研究人員說,過重不只對腰圍不好,對大腦也不好。

專家並不確定原因,但表示代謝的改變,例如高血糖與膽固醇升高,可能有關係。

這份刊登在《神經科學》的研究,追蹤超過六千名英國人的健康狀況。參與者年齡在三十五歲到五十五歲之間,他們在十年間接受三次記憶力或其他認知技巧測試。

過胖且有不健康的代謝改變者,認知測試分數衰退的速度,要比其他參與研究者快。
