The effects of brief diet and anti-diet social media videos on body image and eating concerns among young women

The effects of photo-based platforms on body image concerns are well documented, yet it is unknown whether these effects replicate across video-based platforms such as TikTok. Thus, this experimental study aimed to examine the relationship between video-based platform use and body image. Women aged 18 to 21 (n = 421) were randomly assigned to watch two brief, consecutive TikTok videos in one of three conditions: (1) diet culture, (2) anti-diet, (3) neutral. Participants allocated to the anti-diet condition reported greater increases in weight and shape satisfaction as compared to the diet culture condition, and greater increases in state body appreciation and state intuitive eating as compared to the neutral condition. In addition, those allocated to the diet culture condition reported greater increases in restriction and urges to exercise, and smaller gains in positive mood, as compared to those in the neutral condition. Social media related rumination and thin-ideal internalization potentiated these effects.
