Live Long, Heart Strong (LLHS) is a theory-guided, digital twin-supported nutrition intervention designed to promote cardiovascular health behaviors among emerging adults (18-25 years). Developed using a human-centered design approach and informed by Social Cognitive Theory, the intervention incorporates personalized nutrition education, interactive learning activities, goal setting, self-monitoring, quizzes, youth-informed educational videos, tailored feedback, reminders, and gamification to support healthy eating behaviors and improve dietary quality. In this pilot randomized controlled trial, participants will be randomly assigned to either the LLHS intervention or an active comparator consisting of a static, non-personalized digital nutrition education toolkit containing similar evidence-based educational content without personalization, interactivity, or behavioral support features. The study will evaluate implementation outcomes (feasibility, usability, acceptability, and appropriateness), changes in psychosocial and behavioral outcomes related to healthy eating, and preliminary cardiovascular-related health indicators. Findings will inform continued refinement of the LLHS intervention and the design of a future fully powered efficacy trial.
