Background/Objectives: Dietary behavior in eating disorders (EDs) is often framed through either nutritional or psychological perspectives, yet emerging evidence suggests that eating may involve a transdiagnostic, emotionally embedded, and relationally negotiated process. While research highlights the role of emotion regulation difficulties, perfectionism, control, and overvaluation of weight and shape in ED maintenance, less is known about how these processes are interpreted and managed in clinical practice across different cultural contexts. This study explored psychotherapists’ perspectives on dietary behavior, nutritional assessment, and interdisciplinary collaboration in ED treatment in Greece and the United Kingdom. Methods: Eighteen psychotherapists (9 Greek and 9 British) with experience in treating individuals with EDs participated in in-depth semi-structured interviews. Data were analyzed using reflexive thematic analysis. Results: Three themes were developed. First, therapists conceptualized dietary behavior as reflecting broader transdiagnostic psychological processes, particularly perfectionism, control, emotion regulation difficulties, and body image concerns. Second, nutritional assessment and intervention (e.g., food diaries and meal plans) were experienced as emotionally significant practices that required negotiation of timing, meaning, and clients’ readiness for change. Third, interdisciplinary collaboration was described as involving ongoing negotiation of nutritional authority, with therapists balancing nutritional considerations and psychological safety, influenced by contextual differences between UK and Greek mental health systems. Conclusions: Findings suggest that dietary behavior in ED treatment may benefit from approaches that integrate psychological and nutritional perspectives. Clinicians may consider attending to clients’ emotional readiness, the symbolic meanings of food, and the dynamics of multidisciplinary collaboration, offering insights that can inform clinical practice and future research.
