Exposure to different bodies modulates eye movements to high- and low-calorie foods

Studies indicate that exposure to images of bodies influences eating behaviors and cognitions. For example, exposure to thin models is associated with increased chocolate avoidance and guilt, whereas exposure to overweight models is related to decreased chocolate approach and guilt (Durkin et al., 2012). The current study sought to determine if exposure to bodies influences gaze behavior to different foods. Participants (46 undergraduates, 6 males, mean age = 22.3, mean BMI = 24.8) were assigned to one of two body viewing conditions (thin or heavy bodies). First, each participant viewed pairs of savory or sweet food images that varied in their calorie content (high vs. low). After viewing same sex bodies that were either heavy or thin, participants viewed another set of food images. Eye movements were monitored throughout. Analysis of duration to first fixation (attentional orienting) revealed several interactions, including a body viewing condition by time interaction, such that participants took longer to gaze at all foods after viewing heavier bodies. Participants also took longer to fixate on high calorie sweet foods at Time 2, regardless of body viewing condition. With respect to total fixation duration (attentional maintenance), several interactions were noted, including a time x calorie x taste interaction. Specifically, participants looked longer at low calorie (vs. high calorie) savory and sweet foods at Time 1, a difference that disappeared for savory foods after viewing bodies. Overall, results suggest that the effects of body exposure are manifested primarily during attentional orienting, suggestive of food avoidance.
