Eating disorders are complex, under-researched mental disorders with varying presentation forms and impact on physical and psychosocial health.

Research Review: What we have learned about the causes of eating disorders - a synthesis of sociocultural, psychological, and biological research.

Multiple biopsychosocial influences, including idealization of thinness and personality traits, are associated with eating disorders and disordered eating symptoms.

Eating disorders

Eating disorders are a complex and poorly understood issue, with genetic predisposition and environmental risk factors playing a role, and evidence-based management of bulimia nervosa is possible.

Binge eating disorder and obesity

Binge eating disorder (BED) is a common condition with a prevalence of 2-50% in the general population, and both eating disorder and obesity treatments are beneficial, with treatment focusing on disordered eating and associated psychopathology.

Eating disorders

Eating disorders are influenced by central control of appetite, cultural, social, and interpersonal factors, and changes in neural networks, with limited advances in treatment for adults.

Understanding eating disorders

Eating disorders develop and maintain themselves due to brain mechanisms activating when food intake is reduced, and a method based on teaching normal eating, controlling physical activity, and providing external heat has proven effective in a randomized controlled trial.

Disordered eating and obesity: associations between binge‐eating disorder, night‐eating syndrome, and weight‐related comorbidities

Quality of life and eating disorders

Eating disorders significantly impact quality of life, with self esteem being the most significant factor contributing to this poorer state.
