Scientists in search of the Fountain of Youth share their findings. You can try these tricks today.
“With aging, we’ve always studied things that decline,” says Changiz Geula, Ph.D., research professor of neurology at the Cognitive Neurology and Alzheimer’s Disease Center at Northwestern’s Feinberg School of Medicine. But now she and other experts are looking instead to unlock the secrets of the “superaged,” those lucky individuals who seem to stay vital well into their 80s and beyond. Here’s some of their latest research, with advice on how you can add years to your life.
Stop eating so much
In Okinawa, Japan—home to some of the world’s oldest people—centenarians stop eating when they’re 80 percent full, says Dan Buettner, who studies longevity all over the planet and has written The Blue Zones: Lessons on Living Longer from the People Who Have Lived the Longest (National Geographic, 2009).
They’re onto something: Scientists at St. Louis University found that, while both exercising and eating less led to weight loss in the study’s volunteers, cutting calories also lowered production of T3, a thyroid hormone that slows metabolism. The researchers believe that lower T3 levels may also slow the aging process.
