You know those "light and healthy" sections more and more restaurants are putting on their menus? They could be sabotaging your weight-loss efforts: a new study shows that when restaurants create special low-calorie sections on their menus, people tend to automatically rule out those options.
"Because most restaurant menus are quite complex -- offering numerous dishes composed of multiple ingredients -- diners try to simplify their decision. People have come to expect low-calorie food to taste bad or not fill them up," study researchers Jeffrey R. Parker, of Georgia State University, and Donald R. Lehmann, of Columbia University, said in a statement. "We propose that by calorie organizing a menu, restaurants make it easier for people to use the general 'low-calorie' label to dismiss all low-calorie options early in the decision process."
The study
The study included four experiments, all of which involved having study participants view menus and then indicate which dish from the menu they would choose, as well as estimate or recall how many calories were in that dish.
For one of the experiments, researchers had 272 people with an average age of 31 look at a menu for Timmy's Diner (a restaurant none of the participants had ever visited before) and choose a dish and beverage. However, not all the participants' menus were the same.
There were three formats for menus: one of them was a traditional menu that just listed all the items, the second was the same as the first one except there was calorie information labeled by each item, and the third was organized by calorie content and included a separate section specifically for dishes under 700 calories. There were two versions of each of these three menus, with one version having the price positively correlated with calories and the other version having the price negatively correlated with calories. (When price is positively correlated with calories, that means people pay less for low-calorie items, and so in theory would be more likely to pick low-calorie items; the opposite goes for when price is negatively correlated with calories.)
However, people who were given the menus where the low-calorie dishes were in their own separate category chose dishes that were about 11% higher in calories, compared with the dishes chosen by people whose menus only listed the calories by each item.
Bottom line
"Thus, additionally organizing the calorie-posted menus by caloric content largely (though not completely) erased the positive impact of calorie posting," the researchers wrote in the study.
They also noted that the impact of posting calories by each dish in choosing lower-calorie foods was even greater for the menus where the price was positive correlated with calories, "suggesting that price, unsurprisingly, plays a role in consumers' choices."
However, researchers did not find that the calorie-price correlation seemed to affect food choices at all when the participants were given the menus where the low-calorie foods were spun out into their own category. "This supports our contention that consumers use menu categories as a screening criterion," the researchers wrote in the study. "Since many participants likely screened out the under-700-calories options in the consideration set formation process, they would be unlikely to notice the calorie-price correlation, resulting in this factor playing little to no role in their choices."
What do you think about the findings? Do you usually skim right over the "low-calorie" or "diet" sections of menus, since you don't expect the food to be as good?
My opinion? Don't get freaked out or intimidated by these special labels or menus. Healthy food can be super filling and tasty—so just pick the most appetizing thing you see and stop overthinking it!
