A behavioral intervention is a structured, theory-informed strategy that changes health-related behavior by targeting the psychological, cognitive, social, and environmental processes shaping it, typically using techniques such as goal setting, self-monitoring, feedback, stimulus control, and reinforcement, and often organized through frameworks like the Behavior Change Wheel (Michie et al., 2011, PMC).
In nutritional psychology, behavioral interventions are the primary method for supporting sustained change in eating patterns, food choices, and diet-related mental health outcomes, strengthening self-regulation, interoceptive awareness, and adherence to dietary recommendations, and are delivered through counseling, digital tools, group programs, and clinical protocols such as CBT for eating disorders and motivational interviewing–based dietary counseling (Spahn et al., 2010, PubMed).
