Social media algorithms amplify eating disorders among vulnerable users
Research from Itersia - Centro de Psicoterapia reports that social media algorithms, particularly TikTok's, amplify eating disorders by exposing vulnerable users with disproportionate amounts of content about physical appearance, extreme diets and weight loss. Studies show that algorithm-driven content bubbles worsen symptoms in users with eating disorders, with risk determined more by content type than time spent online.
What happened
Itersia - Centro de Psicoterapia released an analysis based on recent studies showing that social media algorithms expose vulnerable users to toxic content that worsens eating disorders (TCA).
An analysis of over one million TikTok videos found that the algorithm shows users with eating disorders a much higher proportion of content related to physical appearance, extreme diets, compulsive exercise and toxic messages linked to eating disorders, compared with users without these conditions.
Research published in Nutrients identified low self-esteem and negative body image as key factors associated with eating disorders, and highlighted the amplifying role that social media plays in these cases. Another study in Frontiers in Public Health found that social media use can harm the self-esteem of adolescents and young adults, contributing to greater body dissatisfaction.
Reported impact
The higher severity of eating disorder symptoms was associated with the algorithm's bias toward showing disorder-related content. Psychologist Sonia Jardí stated: 'People with eating disorders end up trapped in content bubbles that reinforce their symptoms.'
Exposure to content focused on weight loss is associated with lower body appreciation, greater fear of negative evaluation, and more restrictive eating behaviours. The combination of prior vulnerability with massive exposure to weight and body-focused content, amplified by algorithms, increases the probability of developing or worsening eating disorders.
Index analysis
Research found that the risk of eating disorders is not linked mainly to time spent on social media, but to the type of content consumed. Low self-esteem and negative body image are key factors associated with higher eating disorder risk, and social media can function as a 'risk amplifier' for vulnerable populations.
