Leveraging Wearable Technology to Support Behavior Change in Personalized Nutrition and Lifestyle Medicine

Le résumé fourni par la source

Sustained behavior change remains one of the greatest challenges in personalized nutrition and lifestyle medicine, despite well-established links between diet, physical activity, sleep, stress regulation, and chronic disease risk. Consumer health technologies-including activity and sleep trackers, heart rate (HR) and heart rate variability (HRV) monitors, continuous glucose monitors (CGM), and bioelectrical impedance-based body composition scales-provide objective, at-home metrics that translate lifestyle behaviors into measurable physiologic and metabolic feedback. Wearable-derived data can enhance self-awareness, reinforce learning, and support adherence by revealing patterns between lifestyle behaviors and outcomes such as glycemic variability, autonomic balance, energy expenditure, and changes in fat and lean mass. Evidence across domains such as sleep, stress regulation, physical activity, and glycemic response suggests that these tools are most effective when used to identify trends over time between clinical encounters and guide personalized adjustments, rather than as isolated metrics. Integrated within a clinician-guided, patient-centered framework, these technologies can reinforce self-regulation, refine individualized recommendations, and extend care between visits. As digital platforms evolve, integration with AI and emerging biologic insights-including nutrigenomics and the gut microbiome-may further enhance precision. Furthermore, when clinical oversight is maintained, patients may develop greater awareness and agency over the relationships between daily behaviors and physiological responses.
