About those 100 calorie snack packs…

A pair of new marketing studies in the Journal of Consumer Research says they nudge people to eat more. Previously, consumer behavior research has found that people eat more when a large portion is put in front of them.

But one of the new studies, led by Rita Coelho do Vale at the Technical University of Lisbon, found people believe smaller packages help them “regulate hedonic, tempting consumption,” but in fact their consumption can actually increase. Large packages, on the other hand, trigger concern about overeating.

The participants watched episodes of “Friends” and were told the study was about evaluating ads. Bags of potato chips — of differing sizes, of course — were slipped into the test.

The result: Smaller packages are more likely to fuel temptation. “Because they are considered to be innocent pleasures, [small packages] may turn out to be sneaky small sins,” the researchers conclude.

The other study, by three Arizona State researchers, looked directly at those 100 calorie “mini-packs.” The worst overeating is among chronic dieters.

The researchers believe their research shows that the ubiquitous small packages may actually undermine dieters’ attempts to limit calories. “On the one hand, consumers perceive the mini-packs to be a generous portion of food (numerous small food morsels in each pack and multiple mini-packs in each box); on the other hand, consumers perceive the mini-packs to be diet food. For chronic dieters, this perceptual dilemma causes a tendency to overeat, due to their emotion-laden relationship with food.”

In a series of studies, the researchers assessed peoples’ perceptions of M&Ms in mini-packs versus regular-sized packages. They found that participants tended to have conflicting thoughts about the mini-packs: They thought of them as “diet food,” yet they overestimated how many calories the packages contained. In subsequent studies, the researchers assessed participants’ relationship with food, dividing them into “restrained” and “unrestrained” eaters. The “restrained” eaters tended to consume more calories from mini-packs than “unrestrained” participants.

The same issue of the Journal also includes a study on fast food choice architecture, in which restaurants have eliminated the smallest soda sizes in response to customers who pick the middle size. Starbucks already knows this lesson.

    I’m curious to know if these studies controlled for the power of free. Left to my own devices, I ignore junk food. But if I’m at a party and there’s a bowl of Doritos? Watch out, white sofa; I’m about to get some cheese-flavored paw-prints on ya.

    There’s also the social concern about not wanting to look like a cow and manhandling a big bag of chips. Taking a small bag, one at a time, could help maintain a self-image in front of other people as not being a moocher.

    In short: I smell an inadequate study. Now could you pass the big bag o’ chips?
