Wearable technology is changing obesity therapy by facilitating real-time monitoring of physical activity, sleep patterns, heart rate, and energy expenditure. Wearable devices like fitness trackers, smartwatches, and wearable sensors assist individuals and healthcare providers in monitoring progress and engaging in actionable interventions in weight management. To integrate wearable technology into the management of obesity means to provide a personalized means of feedback, goal setting, and behavioral change for improved adherence to practice changes, or lifestyle changes. These devices can also provide more sophisticated, data-driven insight into levels of physical activity, dietary behaviors, and metabolic health, which can be used to increase proactivity in care. Wearable technology is a promising adjunct on the battle against obesity by fostering self-awareness, motivation, and subsequent sustained lifestyle interventions that positively impact metabolic outcomes and long-term health.
