[Eating behavior, eating disorders and obesity].

Area of Science:

• Psychiatry
• Public Health
• Nutritional Science

Context:

• Obesity prevalence has surged in industrialized nations due to changing nutritional and socioeconomic factors.
• Increased societal pressure for thinness has coincided with rising rates of eating disorders.
• Bulimia nervosa and binge-eating disorder are prevalent, particularly among normal-weight to overweight individuals.

Purpose:

• To summarize diagnostic guidelines and therapeutic options for eating disorders.
• To highlight the low detection rate of bulimia nervosa by general practitioners.
• To emphasize the significance of binge-eating disorder in overweight populations seeking weight management.

Summary:

• Bulimia nervosa and binge-eating disorder (BED) are increasing, yet general practitioners detect only about 12% of bulimia nervosa cases.
• BED is common in overweight individuals, with an estimated 20-30% of those in weight loss programs being binge eaters.
• Effective treatment may require modified psychotherapy focusing on normalizing eating patterns before weight loss, and assessment for comorbid conditions like depression, anxiety, and body image disturbances.

Impact:

• Improved identification and management of eating disorders in primary care settings.
• Development of specialized psychotherapeutic approaches for binge eaters.
• Integration of mental health interventions into weight management programs for better outcomes.
