The obesity epidemic is a significant problem in the United States. It is well established that lifestyle factors, such as unhealthy eating and physical inactivity, are key contributors. These causes are generally voluntary activities and it is important to examine health decision-making with respect to these behaviors. The current study examined time-varying factors of stress and mood and their relationship with healthy eating and physical activity in a sample of undergrads (N = 26). Ecological momentary assessment via one's cell phone was used to collect multiple measurements over six days. Positive mood was found to follow physical activity episodes for up to five hours, and preceded physical activity for up until five before the activity occurred. These results are consistent with those from previous literature, and suggest a clear association between positive mood and physical activity. Future research should incorporate more objective measures of physical activity and eating.
