Abstract:
Obesity is a complex public health issue requiring a holistic, interdisciplinary approach. The aim of this narrative review is to present motivational interviewing as a communication-based intervention that supports non-stigmatizing, patient-centered care for individuals with excess body weight, with particular emphasis on fostering intrinsic motivation and sustainable lifestyle change. This narrative review examines motivational interviewing (MI) as a tool to support non-stigmatizing, patient-centered communication and promote behavior change in adults, children, and adolescents with overweight or obesity. Evidence from original studies, systematic reviews, and randomized controlled trials suggests that MI can help improve healthy eating, increase physical activity, and strengthen confidence in maintaining lifestyle changes. Its effectiveness is linked to communication based on empathy, partnership, acceptance, and support, free from stigma, which enhances patient autonomy, and encourages active engagement. Despite promising results, research gaps remain regarding the long-term effectiveness of MI and its integration into routine clinical practice.
