Belly1 fat has long been thought to be particularly bad for your heart, but now, a new study adds more evidence to the idea that it may also be bad for your brain.
 
长期以来,人们都认为腹部肥胖对心脏特别不好,但现在一项新研究提出的新证据表明,它可能还对你的大脑有害。
 
The study, from the United Kingdom, found that people who were obese2 and had a high waist-to-hip ratio (a measure of belly fat) had slightly lower brain volumes, on average, compared with people who were a healthy weight. Specifically, belly fat was linked with lower volumes of gray matter, the brain tissue that contains nerve cells.
 
"Our research looked at a large group of people and found obesity3, specifically around the middle, may be linked with brain shrinkage,” lead study author Mark Hamer, a professor at Loughborough University’s School of Sport, Exercise and Health Sciences in Leicestershire, England, said in a statement.
 
Lower brain volume, or brain shrinkage, has been linked with an increased risk of memory decline and dementia.
 
The new findings, published Jan. 9 in the journal Neurology, suggest that the combination of obesity (as measured by body mass index, or BMI) and a high waist-to-hip ratio may be a risk factor for brain shrinkage, the researchers said.
 
However, the study found only an association between belly fat and lower brain volume, and cannot prove that carrying more fat around the waist actually causes brain shrinkage. It could be that people with lower volumes of gray matter in certain brain areas are at a higher risk of obesity. Future studies are needed to tease out the reasons for the link.
