Digital commitment devices could improve lifestyle and cardiometabolic outcomes by improving physical activity and weight management, thus enhancing cardiometabolic disease prevention. Future research should prioritize long-term trials with extended follow-up periods beyond 12 months to observe physiological improvements and assess maintenance of effects.
