Just thinking about exercise makes me serve more food. Physical activity and calorie compensation

Abstract

Based on the findings demonstrating compensation between mental effort and subsequent food consumption, this article focuses on the compensatory mechanism between thinking about physical activity and food intake. Results from a field experiment indicate that simply reading about physical activity leads participants to compensate by serving themselves more snacks. The amount of snacks served was mediated by biased calorie estimation. Additionally, we also manipulated the way physical activity was perceived (as tiring exercise or as a fun activity). Although results suggest extra consumption when exercise is perceived as tiring, differences were not statistically significant. © 2010 Elsevier Ltd.
