The effects of running wheel activity on food intake and meal patterns were measured under several cost conditions for food in CD1 mice. In a first experiment, voluntary wheel running activity increased daily food intake relative to a sedentary group, and runners consumed bigger but fewer meals. Although they ate more, runners had significantly lower body fat than sedentary mice. In a second experiment, running was used as an approach cost and food access was contingent on running wheel activity. Mice were able to emit more wheel revolution responses compared to a condition in which nose poking was the approach response. In both voluntary and foraging running protocols mice had inelastic demand functions compared to the non-running groups. When running was voluntary (experiment 1), the day-night cycle for activity was more pronounced compared to when running was a foraging or approach activity (experiment 2).
