How to Diet: Is Chocolate for Valentine’s Day the New Superfood?

Do chocolate eaters really weigh less?

With Valentine’s Day just around the corner, you may be thinking about buying chocolate for your loved ones. The idea is probably even more tempting because of all the recent news about how chocolate is good for your memory, your heart, and your waistline. But don’t believe everything you hear. Take chocolate and weight.

“Eat chocolate, lose weight,” claims weight-loss author Cynthia Sass. “A new study by the University of California, San Diego, found that frequent chocolate eaters weigh less, despite consuming more calories,” she wrote in Fox News Magazine.

Many people believe that, says chocolate researcher James Greenberg, an associate professor of health and nutrition sciences at Brooklyn College in New York.

“It’s based on less-than-rigorous cross-sectional studies supposedly showing that those who eat more chocolate weigh less and those who eat less chocolate weigh more.”

But cross-sectional studies—which take a snapshot in time—can’t determine what leads to what, says Greenberg. To get a better handle on that, you need to follow people over time.

To do that, Greenberg analyzed data on chocolate consumption from the Atherosclerosis Risk in Communities (ARIC) study. More than 12,000 residents of North Carolina, Minnesota, Maryland, and Mississippi aged 45 to 64 were weighed in the late 1980s and were asked, among other things, how often they ate a serving of chocolate. Six years later, they were weighed and asked about chocolate again.

“The more frequently someone ate chocolate, the more weight they gained,” says Greenberg. “And those who ate the most chocolate gained the most weight.”

It didn’t take much, either. People who consumed just an ounce of chocolate at least once a week gained an average of 2.4 pounds over the six years.

That’s consistent with the results from a small randomized trial of 91 German men and women. Those given about an ounce of chocolate to eat every night after dinner gained almost two pounds over a three-month period, while those given about a quarter of an ounce gained no weight.

So why do cross-sectional studies seem to show that people who eat more chocolate weigh less?

“Some heavier participants in the studies are eating less chocolate because they’re trying to lose weight after having a heart attack or stroke, or after being diagnosed with a disease like diabetes,” Greenberg explains. “That makes it look like people who eat more chocolate weigh less. But if researchers exclude people who have obesity-related illness, those who eat more chocolate don’t weigh less.”
