At an all-you-can eat buffet in a sports bar, it was tested whether people would eat less if they knew how much they had already eaten. 50 graduate students (34 women; M age = 24.1 yr.) were seated at 21 tables randomly assigned to be bussed (leftover wings removed) or unbussed (wings left on table). The 31 students at the bussed tables ate more than those at the unbussed tables (7 wings vs. 5.5 wings), with the effect being stronger for men than women. In distracting eating environments, environmental cues may provide an effective means of reducing consumption. Implications for controlling alcohol intake were also noted.
A food craving is an intense desire for a food, which is difficult to resist. Studying food cravings is important, because food cravings influence snacking behavior and are believed to contribute to excessive eating and in this way to obesity. The experiment reported here explores the impact of providing participants with ‘just a bite’ of desirable, craving‐inducing foods versus a large amount of these foods. The expectation is that the portion size of a desirable food will impact craving tendencies and appetite at different points in time. Participants were randomly assigned to one of the two conditions where they were presented with small versus large portions of chocolate chips, apple pie, and potato chips. Participants were asked to report their appetite and cravings for those foods before eating, immediately after eating, and 20 minutes after eating. Compared to before eating, cravings were significantly reduced 20 minutes after eating, all Fs > 16.2, ps <.001. Compared to before eating, appetite was also significantly reduced 20 minutes after eating, F > 6.5, p =.002. Importantly, these effects were consistent across the two conditions, ps >.44, suggesting that simply eating just a bite of food, rather than full of food, is enough to reduce food cravings.Marie Curie International Outgoing Fellowship of second author within the 7th European Community Framework Programme.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
