- Eating Disorder Research
Background:
- Diet culture significantly impacts young people's eating behaviors and body image.
- TikTok is a popular platform for sharing health and diet-related content, raising public health concerns.
Purpose of the Study:
- To analyze the portrayal of dieting on TikTok.
- To assess the potential public health implications of TikTok's diet content, particularly concerning eating disorders.
Main Methods:
- A cross-sectional descriptive content analysis of 250 TikTok videos.

Main Results:
- Over half of the videos depicted 'body checking,' a practice detrimental to body image.
- Nearly half of videos discussing body image presented it negatively.
