Disordered eating involves abnormal eating behaviors such as impulsive eating, purging, and food restriction; it is influenced by various factors and is often associated with negative body image. Although these behaviors are less severe than eating disorders, they can still significantly affect body weight and overall health.

The main signs and symptoms of disordered eating include frequent dieting, anxiety about food, chronic weight fluctuations, and rigid food-related rituals. Individuals may also experience distorted thoughts about food and body image and feelings of guilt, and they may engage in compensatory behaviors like exercise or purging.

Disordered eating is identified using the diagnostic tools for eating disorders, but it is not a formal diagnosis because it doesn't meet the clinical criteria. Health providers can assess disordered eating behaviors through questionnaires on dietary history, nutrient intake, and eating habits.

Most interventions for disordered eating are experimental and are not classified as medical treatments. However, a small study indicated that telephone-provided cognitive behavioral therapy was effective in reducing disordered eating among participants who had undergone bariatric surgery.

Intuitive eating and cognitive-dissonance-based group treatment are the most effective interventions for preventing or reducing disordered eating behaviors, and mindfulness shows promise for adults but may not be suitable for adolescents. Additionally, yoga may improve mood, but it does not address disordered eating risk factors, and other body image interventions could also be beneficial.

Disordered eating can be triggered by stressful life events, childhood trauma, and serious health diagnoses; it often develops as a means to regain control. Additional risk factors include dieting, perfectionism, negative self-image, bullying, and problematic social media use, which can lead to body comparison and dissatisfaction.
