Posting calorie counts doesn't affect the consumer's choices

Calories are listed next to menu items at a Chipotle Mexican Grill July 18, 2008 in New York City.

Bob Moon: Ah, the freedom to choose. It's one of our most prized liberties. Especially choosing what we eat. Of course, it helps to know what we're eating.

Tomorrow is the last day the public can weigh in, so to speak, on new rules proposed by the Food and Drug Administration. They'd require that calorie counts be posted by chain restaurants nationwide. Imagine knowing how your meal really stacks up at Taco Bell or Applebee's. Similar laws are already in force in New York City, Seattle and across California. And that's giving us an idea how this might affect our habits.

Nicholas Bagley: Happy to be here.

Moon: Now you've pointed to research that suggests that once restaurants begin posting calorie counts, very little will really change?

Bagley: That's right. We know because New York City has tried; since 2008, chain restaurants in the city have had to post calorie count information. And so researchers compared the food choices that low-income children and adults made in neighboring Newark -- which doesn't require the posting of calorie counts -- with low-income children and adults in New York City. And they found that calorie counts had virtually no effect on what New Yorkers actually purchased.

Moon: Why?

Bagley: Well, nobody's exactly sure. At the outset, some people -- kids especially -- just don't pay any attention to calorie counts. And for those who do see them and do register that they're there, calorie counts can be deceptively hard to use. People may know that they shouldn't eat too many calories, for example, but they may not know how many are too many. And for most people, the choice of what to eat is really driven by taste and cost -- not calorie counts.

Moon: So you're suggesting that maybe we need to post these calorie counts with flashing red lights for the worst ones? Or what?

Bagley: People are attracted in our culture to these informational solutions, to the idea that if we give people the right information, surely they're going to make better decisions. But there's been a ton of research in public policy circles on these sorts of informational solutions, and it turns out that no matter how much information you give people, they still tend to make pretty poor choices pretty consistently.

Moon: One of the other questions that's occurred to me is how are we even sure that these calorie counts that are being posted are accurate?

Bagley: We can't be sure that the calorie counts are accurate. In 2010, researchers at Tufts actually looked into the calories at restaurant food, and they found that the restaurant food contained on average about 18 percent more calories than advertised -- with some items having as many as twice as many calories.

Moon: This all focuses on the consumer's reaction to all this, though. If the restaurants are indeed changing their menus and modifying certain items to reduce calories and sodium content or whatever, isn't that a positive step that's going to have some effect on what consumers do?

Bagley: It's a positive step, but it's too early to tell whether it's just smart marketing. Chain restaurants, and especially fast food joints, have an image problem. People think that they're big contributors to the obesity epidemic. If fixing up a few of their menu items can improve that image and help keep the regulators off their back, that's good for their bottom line. But it remains to be seen whether the restaurants actually make a full-throated commitment to cut the calories for their most popular food items. I have to admit, I'm a little skeptical.

Moon: Well if that's true, what would have an effect?

Bagley: Combating obesity requires a mammoth social commitment. Posting calorie counts just doesn't cut it. We don't need people to eat better in restaurants; we've got to get them out of those restaurants and into their kitchens. And perhaps most challenging of all, we've just got to change people's attitudes about food.

Moon: Nicholas Bagley is an assistant professor at the University of Michigan Law School. Thanks for burning a few calories with us.

Bagley: Happy to do it.

Are you kidding? Knowing the calorie, fat, and sodium content of ALL "junk-food" places is what stops me from going there! It's gross what people will eat just because it's fast, easy, and cheap. Taste? I don't like the feeling of a thick layer of fat on the roof of my mouth, not to mention what it does to the body. There is a crisis right now- obese people and even children, as we also waste millions on diet plans and product that don't work. What a weird world.

As a family physician, I often find that "talking to the head" results in more informed consumers who continue to elicit the same behavior. Changing attitudes will certainly do more to motivate longlasting behavioral changes but getting there will be very challenging. Perhaps looking in areas such as behavioral economics that make the healthy choice the default choice will possibly begin to change immediate behaviors which then may influence attitudes.

Calorie information on menu definitely affected my choice when taken to Applebee's.

Given that I go out to eat to get calories (my stomach signaling to me that I need more), and I know how much I can eat to stop my stomach from wanting more, I don't see these numbers changing my eating habits at all.

I know I will never even think about reading the calorie counts.

I, for one, am a person who, if given the right information, will make a better decision. Two or three times a month I have been given to driving thru a fast-food chain restaurant for a snack, while I am out on the road doing errands. I strive for a snack that is 100 or 150 calories.

Ofetn, my choice has been an order of 5-piece chicken nuggets at Wendy's, thinking "how bad can 5 little pieces of protein be?" Well, now I know. I looked it up online the other day and was, in a word, HORRIFIED.

They are 230 calories and between 45 and 120 calories more with sauce!

There isn't anything on their menu near 100 calories except salad garnishes and sauces and a few meat, fish or chicken items minus the buns.

Rest assured, I am not stopping for a snack at Wendy's or its ilk again.

Hi Bob!
I suspect that posting calorie counts won't "count" except to dieters, who most likely wouldn't (or at least shouldn't) be in a fast food joint in the first place.
Also, after discovering Marketplaces "brown bag" calculator, and knowing just how materialistic this society is, I wonder, Might that be a more effective tool?
