'Healthy' restaurants help make us fat, says a newl study

If you're like most, you eat worst at healthy restaurants. The "health halos" of healthy restaurants often prompt consumers to treat themselves to higher-calorie side dishes, drinks or desserts than when they eat at fast-food restaurants that make no health claims, according to a series of new Cornell studies.

The research, published in the October online version of the Journal of Consumer Research, found that many people also tend to underestimate by 35 percent just how many calories those so-called healthy restaurant foods contain.

"We found that when people go to restaurants claiming to be healthy, such as Subway, they choose additional side items containing up to 131 percent more calories than when they go to restaurants like McDonald's, that don't make this claim," says Brian Wansink, author of "Mindless Eating: Why We Eat More Than We Think" (Bantam 2006) and the John S. Dyson Professor of Marketing and of Applied Economics and director of the Cornell Food and Brand Lab.

Wansink and co-author Pierre Chandon, a marketing professor at INSEAD, an international business school in France, also report that by simply asking people to reconsider restaurants' health claims prompts them to better estimate calories and not to order as many side dishes.

They recommend that public policy efforts help people to better estimate the number of calories in foods.

"In estimating a 1,000 calorie meal, I've found that people on average underestimate by 159 calories if the meal was bought at Subway than at McDonald's," says Wansink. Since it takes an energy imbalance of 3,500 calories to put on one pound, that extra 159 calories could lead to almost a 5-pound weight gain over a year for people eating at Subway twice a week compared with choosing a comparable meal at McDonald's with the same frequency, he says.

These studies, he says, help explain why lower-calorie menus at fast-food restaurants have not led to the expected reduction in total calorie intake and in obesity rates.

Children's consumption of sugar-sweetened beverages
A recent study published in Pediatrics and led by researchers at Columbia University Mailman School of Public Health found that sugar-sweetened beverages (SSBs) are an increasingly large part of children and teens' diets. Teens who consume SSBs, which include sodas, fruit drinks and punches, and sports drinks, drink an average of 356 calories per day, a significant increase from 10 years earlier. The findings suggest that reducing empty caloric intake by limiting these drinks may be a key strategy for promoting healthy eating and preventing excess weight gain.
You're likely to order more calories at a 'healthy' restaurant
An important new study from the Journal of Consumer Research explains the “American obesity paradox”: the parallel rise in obesity rates and the popularity of healthier food. In a series of four studies, the researchers reveal that we over-generalize “healthy” claims. In fact, consumers chose beverages, side dishes, and desserts containing up to 131% more calories when the main dish was positioned as “healthy”.
