Description
Summary:The current work demonstrates that people serve themselves greater amounts of food when carrying heavier serving dishes. This effect occurs because increases in carried weight lower consumers’ sensitivity to the weight of the food served. Decreased sensitivity to weight of food served in turn leads people to continue serving past the point where they would normally stop. The paper demonstrates this effect across two lab studies involving actual food serving (with a third lab study extending the outcomes to unhealthy food choices reported in the S1 Appendix). The studies also demonstrate liking for the food moderates the effect, such that carrying greater weight leads people to serve an increased amount of liked, but not of less well liked, foods. The findings extend prior research regarding the effects of dish weight on food judgment to provide a first demonstration of effects of weight not only on judgment but on behavior. In this, they help expand our understanding of the ways in which elements in the eating environment effects food consumption. In addition, the studies provide initial evidence for the mechanism behind the phenomenon: reduced sensitivity to weight. The research carries important implications for public well being, given that increases in serving sizes may contribute to obesity.
