What research says about social media and eating disorder risk

Eating disorders are complex and usually have more than one contributing factor. But a growing body of research links certain kinds of social-media exposure — especially appearance-focused content, social comparison, thin-ideal imagery, fitness and diet content — to eating-disorder risk in adolescents and young adults.

The strongest evidence is not just about screen time.

The strongest research focuses on what users are exposed to, how algorithms reinforce content, and how appearance-based comparison affects vulnerable adolescents and young adults.

This is important because the litigation focuses on platform design, recommendation systems, harmful content exposure, and compulsive use — not merely the fact that young people spent time online.

Broad research reviews

Several high-level research reviews have examined the relationship between social media, body image, and eating-disorder risk.

2023 PLOS Global Public Health scoping review

This review examined 50 studies across 17 countries. It concluded that social-media use is a plausible risk factor for clinical and subclinical eating disorders in young people. Possible mechanisms identified include social comparison, thin-ideal internalization, self-objectification, pro-eating-disorder content, and appearance-focused platforms.

Systematic review and meta-analysis on online social comparison

This review examined the relationship between online social comparison, body-image concerns, and eating-disorder symptoms. It found significant associations between higher online social comparison and both body-image concerns and eating-disorder symptoms.

National Academies consensus report

The National Academies recognized that much social-media research is associative rather than fully causal. But the report identified serious concerns involving body image, body satisfaction, disordered eating, and related issues among adolescents.

U.S. Surgeon General advisory

The U.S. Surgeon General warned that the safety of social media for children and adolescents has not been established and identified harmful content and unhealthy patterns of use as meaningful concerns. The advisory noted that many adolescents report social media makes them feel worse about their body image.

Experimental and causal evidence

Experimental studies are important because they can provide stronger evidence than simple correlations.
These studies help show how exposure to certain kinds of content or reductions in social-media use affects body image and eating-disorder-related outcomes.

2024 PLOS ONE TikTok experiment involving pro-anorexia content

A 2024 study exposed female-identifying participants ages 18–28 to either pro-anorexia or neutral TikTok content. The group exposed to pro-anorexia content experienced the greatest decrease in body-image satisfaction and increased internalization of societal beauty standards.

Randomized trial reducing social-media use

A randomized trial involving youth ages 17–25 limited social-media use to one hour per day for three weeks in the intervention group. The study found improved appearance and weight esteem among participants who reduced their social-media use.

Evidence involving
adolescents and young adults

Young adolescent study

This study found a clear pattern of association between social-media use and disordered-eating thoughts and behaviors in young adolescents. That finding matters because many potential claims involve social-media use beginning before age 18.

Nationally representative young-adult sample

This study reported a strong and consistent association between social-media use and eating concerns in a nationally representative sample of young adults.

Platform, content, and algorithm evidence

The litigation is not based only on the amount of time a young person spent online. It also focuses on the type of content shown, the way recommendation systems can reinforce harmful interests, and how platform design may have contributed to compulsive use or harmful content exposure.

Exposure type may matter more than raw screen time

A 2023 review found that exposure to weight-loss and appearance-focused content is associated with poor body image and disordered eating, while duration of use alone is not always predictive. This points to product design, content exposure, and algorithmic recommendation.

American Academy of Pediatrics guidance

The AAP warns that social-media trends and keywords depicting disordered eating change constantly and recommends that clinicians and parents ask teens about online content, unrealistic body types, and unhealthy weight-loss approaches.

Meta/Facebook internal research — Wall Street Journal

The Wall Street Journal reported on internal Facebook research concerning Instagram and teen girls, including internal concerns about body image. Meta acknowledged that body image was an area where some teen girls who struggled with that issue said Instagram made it worse more often than better.

Reuters report on internal Meta research

Reuters reported on internal Meta research involving teen users and “eating-disorder-adjacent” and body-focused content on Instagram. The report is relevant to concerns about vulnerable users, content exposure, and algorithmic amplification.
