Abstract:
Introduction: Experimental research has examined the effect of social media on body dissatisfaction, but little attention has been given to the impact on eating behavior. Across two studies, we tested the causal relationship between acute social media use, body dissatisfaction and eating behavior. Methods: In Study 1, 80 female participants (age: M = 20.75 years; BMI: M = 21.3) viewed their own Facebook account or a news website before completing a portion size selection task. In Study 2 (pre-registered), 148 participants (81 females; age: M = 20.92 years; BMI: M = 22.19), viewed their own or an experimenter-curated Instagram profile before consuming potato chips ad-libitum. Results: In Study 1, body dissatisfaction was significantly higher in participants who viewed Facebook (compared to a news website) and significantly mediated the effect of condition on portion size selection. In Study 2, regardless of condition females reported significantly smaller ideal body sizes and higher body dissatisfaction compared to males. When females reported a thinner body size as ideal, females in the personal Instagram consumed significantly less potato chips than those in the control Instagram condition. When males reported a smaller actual body size, males in the personal Instagram condition consumed significantly less potato chips than males in the control Instagram condition. Discussion: Findings suggest brief bouts of social media use may produce immediate disruptions to body image of both sexes, and restrained snack intake of females endorsing thin ideals.
