Should You Eat like a Caveman?

By Jennifer Pinkowski

Most New Year's resolutions have an awfully short shelf life. By the end of January, folks who swore they would lose weight and shape up may already be back on the Krispy Kremes. But that's not entirely our fault, claims Arthur De Vany, a former economics professor at the University of California, Irvine. In his new book, The New Evolution Diet, De Vany argues if we really want to get fit, we should follow the lead of our ancient ancestors, Paleolithic humans who lived as nomadic hunter-gatherers some 40,000 years ago.

For more than 25 years, De Vany has been an advocate of what he calls "evolutionary fitness": a regimen of low-carb eating and interval- or cross-training workouts (with periodic fasting) aimed at controlling insulin. But he has also become the grandfather of the growing Paleo movement, a health philosophy built around the belief that modern life — dating from the advent of agriculture 10,000 years ago — is simply alien to our genes. Believers say that only by returning to a diet of wild game and fresh produce, eliminating grains and dairy, and exercising in short, intense bursts, can we thrive in a world of escalators and cheese fries. (See 10 new diet books for 2011.)

Is Sugar Toxic?

By GARY TAUBES

On May 26, 2009, Robert Lustig gave a lecture called “Sugar: The Bitter Truth,” which was posted on YouTube the following July. Since then, it has been viewed well over 800,000 times, gaining new viewers at a rate of about 50,000 per month, fairly remarkable numbers for a 90-minute discussion of the nuances of fructose biochemistry and human physiology.

Lustig is a specialist on pediatric hormone disorders and the leading expert in childhood obesity at the University of California, San Francisco, School of Medicine, which is one of the best medical schools in the country. He published his first paper on childhood obesity a dozen years ago, and he has been treating patients and doing research on the disorder ever since.

The viral success of his lecture, though, has little to do with Lustig’s impressive credentials and far more with the persuasive case he makes that sugar is a “toxin” or a “poison,” terms he uses together 13 times through the course of the lecture, in addition to the five references to sugar as merely “evil.” And by “sugar,” Lustig means not only the white granulated stuff that we put in coffee and sprinkle on cereal — technically known as sucrose — but also high-fructose corn syrup, which has already become without Lustig’s help what he calls “the most demonized additive known to man.”
