Recent research describes social media as a significant risk factor in the pathway from body image concerns to disordered eating, particularly for vulnerable adolescents, rather than the sole cause of eating disorders.
A 2023 scoping review in PLOS Global Public Health mapped 50 studies from 17 countries and found that social media usage is consistently associated with body image concerns, disordered eating, and eating disorders through mechanisms such as social comparison, self-objectification, and internalization of thin or “fit” ideals.
Highly visual platforms that prioritize photos and short videos appear especially related to elevated eating disorder risk in adolescents and young adults, with gender differences in how young people engage and how often they encounter appearance-focused content.
In the same period that social media use became woven into daily life, eating disorder statistics among adolescents have shifted sharply.
One multi-site analysis of U.S. health datafound a 107.4 percent increase in eating disorder–related health visits for individuals under 17 between 2018 and 2022, with total visits rising from roughly 50,000 to more than 100,000 during that span, a change that authors linked in part to pandemic-era disruptions.
Studies of pediatric hospitals likewise report that emergency department visits and hospitalizations for eating disorders in children and teenagers roughly doubled after the onset of COVID-19 and remained elevated through at least mid-2022.
During those same years, surveys found that a majority of parents reported their tweens and teens spending more time on screens and social media during lockdowns, often using new accounts and devices as school, activities, and in-person contact moved online.
Key findings from recent research include:
- Pathways of risk: Across multiple studies, social media use is linked to body image concerns and disordered eating through repeated exposure to idealized body types, appearance-based comparison, thin-ideal internalization, and self-objectification.
- Time online matters: Heavier or more frequent use, especially time spent engaging with appearance-focused posts, is associated with higher levels of body dissatisfaction, dieting behaviors, and compensatory behaviors in adolescents.
- Pandemic effects: Eating disorder diagnoses and acute care visits for young people rose steeply in the years that overlapped with COVID-19, when social isolation, stress, and increased social media use occurred together.
- Vulnerability and moderators: Being female, already dissatisfied with one’s body, having higher body weight, or experiencing bullying and weight stigma appear to amplify the impact of harmful content, while positive body image and stronger social media literacy can weaken these effects.
- Content type and repetition: Exposure to pro-eating-disorder content, aggressive dieting trends, or “ideal” body types multiple times per day is associated with more severe symptoms, whereas feeds that contain more diverse body types and less appearance-focused material show a different risk profile.
- Interventions: Experimental work suggests that when distressed teens and young adults spend less time on social media, cutting use by about half, they often report measurable improvements in body image and how they feel about their weight after only a few weeks.
Taken together, these findings suggest that vulnerable young people can enter a self-perpetuating cycle of risk: education about media effects may be limited, they encounter idealized content, they compare their own bodies to those images, and then the algorithm presents more of the same material each time they log in.
For some, this process begins with relatively mild dissatisfaction and progresses to restrictive dieting, compulsive exercise, or other disordered behaviors as they interact with the same types of posts multiple times a day.
On the flip side, researchers note that not all social media exposure is harmful and that careful curation, stronger education, and more varied, body-positive content can help some users engage with platforms while reducing pressure to match a single “ideal” look.
For families and clinicians, these data point toward practical steps such as spending less time on appearance-obsessed feeds, teaching critical skills for evaluating what shows up on screen, and building offline support when social media use and eating behaviors start to interact.
Social Media and Anorexia Nervosa
Anorexia nervosa is one of the eating disorders young people may develop as a result of harmful social media exposure.
Anorexia is a serious mental health condition that can have severe physical health consequences, including malnutrition, electrolyte imbalances, and heart problems.
Anorexia nervosa usually involves an intense fear of gaining weight and a distorted body image, leading victims to extreme food restriction and excessive exercise to lose weight.
A person with anorexia may exhibit the following symptoms:
- Dramatic weight loss
- Refusal to maintain a healthy weight
- Intense fear of gaining weight or becoming fat
- Distorted body image, seeing themselves as overweight even when underweight
- Anxiety around food and eating in public
- Obsessive-compulsive behavior around calorie counting, food restriction, and exercise
- Amenorrhea or the absence of menstrual periods
- Social withdrawal and isolation
- Sleep disturbances
- Irregular or abnormal heart rhythms
- Difficulty concentrating and changes in mood or behavior
- Hair loss and other physical changes due to malnutrition
Social media can perpetuate and exacerbate these symptoms by promoting unrealistic body standards, triggering comparison among users, and encouraging unhealthy dieting behaviors.
A 2016 study in the Journal of the Academy of Nutrition and Dietetics found a strong and consistent correlation between social media use and eating disorders, which was evident whether in volume or frequency of use.
According to the study, one-third of anorexia-related videos on YouTube are pro-ana (pro-anorexia), perpetuating harmful messages and behaviors.
Worse, these pro-ana videos received more views and comments than informative non-pro-ana videos.
Moreover, maladaptive use of Facebook, such as comparing oneself with others, is associated with increased body dissatisfaction and disordered eating behaviors among young women.
Without a doubt, social media has played a significant role in the rise of anorexia nervosa.
Whether users see “thinspiration” posts (content that promotes thinness as an ideal) or “bonespiration” images (content that glorifies skeletal and extremely thin bodies), constant exposure to these harmful messages can lead to severe physical and mental health consequences.
As young people attempt to attain the “perfect” body shape and weight, they may engage in disordered eating behaviors, resulting in social media anorexia.
Social Media and Bulimia Nervosa
A person with bulimia nervosa engages in episodes of binge eating (consuming large amounts of food) followed by purging, which can take the form of self-induced vomiting, excessive exercise, or laxative use.
The individual may also exhibit weight fluctuations and a preoccupation with food and body image.
According to a 2023 study in the Journal of Eating Disorders, social media use, depression, anxiety, and bulimia are all connected.
The study found that high levels of problematic social media use can increase depressive symptoms, which in turn can worsen anxiety symptoms.
As a result, the individual may engage in harmful compensatory behaviors like binge eating and purging to cope with these negative feelings.
Interestingly, problematic social media use can also aggravate bulimic behaviors, indicating a strong and direct correlation between the two.
A person with bulimia may have the following symptoms:
- Recurrent episodes of binge eating, often with feelings of lack of control
- Purging behaviors after binge-eating episodes
- Fear of gaining weight or becoming fat
- Frequent use of laxatives, diuretics, or enemas to control weight
- Damaged teeth and gums due to frequent vomiting
- Acid reflux disorder
- Gastrointestinal problems
- Irregular menstrual periods
- Dehydration and electrolyte imbalances
Social Media and Binge-Eating Disorder (BED)
Binge-eating disorder is arguably the most common eating disorder in the country, as it affects all ages, genders, and racial and ethnic groups.
Similar to bulimia, an individual with BED engages in episodes of binge eating.
However, unlike bulimia, they do not engage in purging behaviors afterward.
This disorder can lead to significant weight gain and obesity.
Those with BED frequently experience feelings of guilt, shame, and disgust after a binge episode, leading to social withdrawal and isolation.
Common binge-eating disorder symptoms include:
- Recurrent episodes of binge eating with feelings of lack of control
- Eating much faster than normal
- Consuming large amounts of food even when not physically hungry
- Eating alone due to embarrassment about the amount consumed
- Feelings of guilt, shame, and disgust after a binge episode
- Preoccupation with body shape and weight
- Depression and anxiety
- Difficulty concentrating and changes in mood or behavior
- Diabetes, high blood pressure, and other health conditions associated with obesity
A 2022 review examined various literature on the impact of social media on binge-eating behaviors and found a significant correlation between the two.
The study revealed that individuals who spent extended hours and more frequently used social media platforms tend to have an increased appetite and intention to eat.
As a result, they may engage in binge eating behaviors to cope with negative emotions or as a form of distraction.
Other Social Media Eating Disorders
While anorexia nervosa, bulimia nervosa, and binge-eating disorder are the most commonly recognized eating disorders, other types of disordered eating can also develop as a result of social media exposure.
Other eating disorders potentially linked to social media use include:
- Orthorexia Nervosa: Orthorexia nervosa is an obsession with “clean” or healthy eating to the point of leading to drastic weight loss and malnutrition.
- Individuals with orthorexia may spend hours on social media looking for the “perfect diet” or following influencers who promote extreme eating habits. According to a 2017 study, this condition is prevalent in Instagram but not in other social media platforms.
- Avoidant/Restrictive Food Intake Disorder (ARFID): The pressure to conform to societal beauty standards can also contribute to avoidant/restrictive food intake disorder (ARFID), particularly in young individuals who develop disordered eating patterns due to anxieties around their physical appearance. ARFID refers to a limited food intake and can lead to significant weight loss and malnutrition.
- Night Eating Disorder: A person with a night eating disorder consumes a substantial portion of daily calories after dinner, late at night, or even in the middle of the night after waking up from sleep. It is often associated with poor sleep patterns and can lead to obesity and other health complications.
