Slim Your Waist, Protect Your Brain
Losing a few pounds may help you stay sharp. A study of 1,289 adults in the journal Neurology found that having a higher BMI and waist circumference was associated with having a thinner cortex, which has been tied to worse cognition in late life. Researchers suspect the chronic inflammation caused by obesity may play a role, and the discovery provides yet another reason to maintain a healthy weight. “Dementia is a growing burden in the U.S., and there are no curative therapies, so focusing on risk factors you can modify, such as being overweight, can help,” says Michelle Caunca, Ph.D., lead study author and medical scientist in training at the University of Miami Miller School of Medicine.
