AI in Lifestyle Medicine

Artificial intelligence (AI) is rapidly transforming clinical medicine, yet its application in lifestyle medicine (LM) has only begun to be described systematically. This article synthesizes real-world experiences from three diverse clinical settings (a regional health system, a large academic medical center, and a lifestyle medicine specialty clinic) to illustrate how AI can optimize LM delivery while preserving the human connection at the heart of care. We describe the use of ambient AI scribes to reduce documentation burden and restore clinician-patient presence; AI-enabled analysis of structured lifestyle questionnaires and wearable data to personalize counseling and accountability; AI tools for rapid evidence retrieval; and generative AI to accelerate development of group medical visit curricula and patient education materials. Early outcomes include reduced documentation time, improved provider well-being, enhanced patient engagement, and the ability to scale high-touch LM interventions. We align these applications with the Quintuple Aim of better outcomes, lower cost, improved patient and provider experience, and health equity, and we outline practical steps, ethical considerations (including the environmental and community costs of AI infrastructure), and future directions for "precision lifestyle medicine." When deployed responsibly, AI functions as a force multiplier that amplifies the reach and impact of lifestyle medicine clinicians.
