Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) represent a major advancement in obesity treatment, offering robust efficacy in weight loss and metabolic regulation. Beyond these effects, emerging evidence indicates that GLP-1 RAs also modulate appetite, reward sensitivity, and self-regulation, domains that intersect with behavioral and psychological functioning. This review adopts a biopsychosocial perspective to examine how GLP-1 RAs interact with eating behavior, mood, identity, and self-regulation, particularly in individuals with binge eating disorder (BED) or other psychiatric comorbidities. A clinical framework is proposed to integrate pharmacotherapy with lifestyle and psychological interventions. The temporary reduction in appetite and food reward may create a "low-drive window" in which behavioral strategies such as self-monitoring or stimulus control become more effective. However, high emotional eating, mood symptoms, or identity conflicts may moderate treatment response. Given the high prevalence of psychiatric comorbidities, structured screening using tools like the Patient Health Questionnaire-9 (PHQ-9) or Binge Eating Scale (BES) is recommended. A stepped-care approach from brief digital interventions to formal psychotherapy may help address varying support needs. Crucially, weight regain after discontinuation is common. The review discusses behavioral, psychological, and social mechanisms of relapse and highlights strategies for long-term stabilization. These include emotion regulation, body image work, and maintenance-focused behavioral interventions. GLP-1 RAs should therefore be seen not as standalone treatments but as facilitators of self-directed, sustainable change within integrated care models. Future research should define composite outcomes, explore digital tools for relapse prevention, and develop adaptive pathways tailored to individual psychological profiles.
