The goal of the current study was to determine the extent to which exercise or exposure to exercise through exercise-related reading material affect attentional bias to high- and low-calorie foods in restrained and emotional eaters. Ninety-three female undergraduates participated for 20 minutes in either an Exercise condition (n = 32), in which they exercised on a stationary bike; an Exercise magazine condition (n = 30), in which they read a magazine about exercise, or a Neutral magazine condition (n = 31), in which they read a magazine that was not about exercise. Attentional bias was assessed prior to and following the exercise manipulation through a dot probe paradigm that used picture pairs consisting of a high- or low-calorie food and a non-food object. Restrained eaters relative to unrestrained eaters exhibited an attentional bias away from images of high-calorie foods irrespective of time or condition. Non-emotional eaters, on the other hand, exhibited decreased attention bias towards both high- and low-calorie foods following exercise. They also exhibited decreased attentional bias to images of low-calorie foods after reading a neutral magazine. These results suggest responses to high- or low-calorie foods in females depend on levels of dietary restraint and that interventions, such as exercise, differentially affect attentional biases to foods depending on the eating habits of the individual.
