Is it True that Overweight People Live Longer?

Some evidence suggests that overweight people live longer, but the evidence is suspect. Here's the lowdown.

Diabetes. Cancer. Heart disease. Stroke. Extra pounds raise the risk of nearly every health threat facing Americans. Yet, the Journal of the American Medical Association (JAMA) published—and publicized—a study suggesting that overweight people live longer.
“It’s extremely frustrating,” says Michael Thun, vice president emeritus for surveillance and epidemiology research at the American Cancer Society. “It perpetuates a myth.” Here’s how.

At first glance, the new JAMA study seems impressive.   Read More

The CR Diet Truth: Will Calorie Restriction Prolong your Life?

A calorie restriction diet, or CR diet, may offer the benefit of a longer life, but is it worth it?

“We’ve known for a long time that if you reduce the calorie intake of rats or mice, they live much longer,” says Mark Mattson, chief of the laboratory of neurosciences at the National Institute on Aging (NIA) in Baltimore.

Why the different results? One possibil­ity: The Wisconsin monkeys were fed few­er calories than monkeys fed as much high-sugar, high-fat food as they want­ed. In contrast, the NIA monkeys were fed fewer calories than monkeys fed as much (low-sugar, low-fat) food as they needed to maintain their weight.   Read More

But several glimpses of new evidence are giving researchers renewed hope. They’re looking not just at how many calories people eat and burn, but at their genes, the microbes in their gut, how much they sleep, and more.
