Hard stop: reestablishing the significance of abstinence in the treatment of late stage ultra-processed food addiction.

Addiction is a complex neurobiological disorder characterized by compulsive drug-seeking and use despite harmful consequences. While abstinence-based approaches have long been the cornerstone of addiction treatment, recent years have seen legitimate challenges from harm reduction clinicians, and within the food addiction realm, the eating disorder treatment practitioners. This perspective emphasizes the role of abstinence in food addiction recovery using the Koob model and its concept of hyperkatifeia despite these reservations. However, further research is essential before abstinence can be recommended. We need to 1) identify what qualifies as abstinence in relation to ultra-processed food, 2) clarify suitable situations and disease progression for optimal implementation of this approach, 3) provide clear guidelines when it is harmful, and 4) conduct clinical studies to confirm the effectiveness of this strategy for long-term recovery from late-stage food addiction.
