Snacks in small packages may lead to overeating

TEMPTING treats are being offered in small package sizes these days, presumably to help consumers reduce portion sizes. Yet new research found that people actually consume more high-calorie snacks when they are in small packages than large ones. And smaller packages make people more likely to give in to temptation in the first place.

Authors Rita Coelho do Vale (Technical University of Lisbon), Rik Pieters, and Marcel Zeelenberg (both Tilburg University, the Netherlands) found that large packages triggered concern of overeating and conscious efforts to avoid doing so, while small packages were perceived as innocent pleasures, leaving the consumers unaware that they were overindulging.
