#WhatIEatInADay: The effects of viewing food diary TikTok videos on young adults' body image and intent to diet.

The rise of short-form video content has prompted research into its impact on body image; however, little remains known regarding the effects of exposure to food-related content of this type. The present study aimed to fill this gap in the literature by conducting a between-subjects experiment (N = 316) examining the effects of exposure to low-calorie versus high-calorie "What I Eat in A Day" food diary TikTok videos on young adults' body appreciation, body dissatisfaction, and diet intentions. Additionally, this study sought to explore how social comparison and mood might affect participants' responses to these videos.
