Study Reveals Excessive Smartphone Use Can Contribute to Eating Disorders

Excessive smartphone use may be contributing to eating disorders among young people, according to a recent study published in the Journal of Medical Internet Research. While smartphones are commonly associated with eye strain and negative mood, the research suggests that being psychologically dependent on these devices can also affect eating behaviors and body image.

The study found that young people who feel anxious without their phones or are unable to control their usage—referred to as “Problematic Smartphone Use” (PSU)—are more likely to struggle with food-related issues and dissatisfaction with their bodies. Even without a formal diagnosis, these individuals often display early warning signs, such as emotional overeating or negative self-perception regarding appearance.

Researchers analyzed 35 studies involving more than 52,000 participants, with an average age of 17, from around the world. The findings indicate that teenagers are particularly vulnerable, as this is a developmental stage when they often define their identity by comparing themselves to others. Constant exposure to idealized body images online may exacerbate feelings of inadequacy and dissatisfaction.

The study highlighted several key patterns, including emotional overeating, uncontrolled eating, and food addiction. Negative effects were particularly pronounced for those using smartphones for more than seven hours a day. High usage was also associated with elevated levels of body dissatisfaction, while PSU was identified as a risk factor beyond mere screen time, characterized by withdrawal symptoms, lack of control, and distress in daily life.

Researchers emphasize that while smartphones do not directly cause eating disorders, they are a significant risk factor. They suggest that healthcare providers should consider patients’ digital habits when addressing eating concerns. Reducing screen time and promoting healthy digital habits may be as crucial as traditional interventions in preventing disordered eating.

Beyond eating behaviors, excessive smartphone use poses additional risks, including increased anxiety, depression, sedentary lifestyles, eye strain, sleep disturbances, reduced productivity, and even higher accident risk. Experts recommend setting boundaries, engaging in digital detoxes, and pursuing real-world activities to maintain both mental and physical well-being.
