Novel energy balance tracking to support personalised AI health coaching: a real-world evaluation of the ENHANCE framework
ENHANCE framework provides low-burden, accurate energy balance (EB) tracking for AI coaching.
Combines smart device data and minimal self-report, suitable for free-living conditions.
Achieved high adherence (94% weight, 100% self-report) during a high-risk festive period.
Corrected trends explained 90.4% of smoothed variance, with low mean absolute error (46g vs 77g raw).
Enhanced interpretability and biological plausibility of EB insights.
Executive Impact
Leveraging AI for personalized health coaching offers significant advantages in accuracy, user engagement, and health outcomes. This research highlights the practical application and efficacy of novel energy balance tracking.

Real-World Festive Period Evaluation
The ENHANCE framework was tested during the challenging Christmas to New Year 2024/25 period, a time notorious for increased energy intake and reduced expenditure. Despite these disruptions, participants demonstrated an average net fat weight gain of +0.8 kg (0.4 kg) and a mean net EB of +223 kcal/day (130 kcal/day) over the monitoring phase. The system maintained 94% weight measurement adherence and 100% EB-related submission compliance, showcasing its robustness and low burden even in high-risk scenarios, paving the way for continuous, personalized AI coaching.

Implementation Timeline
Our phased approach ensures a smooth and effective integration of AI into your existing infrastructure.
Phase 1: Foundation & Data Integration (2-4 Weeks)
Secure API integration with smart devices (scales, wearables) and mobile apps. Implement robust data anonymization and storage compliant with healthcare standards. Initial model training with anonymized historical datasets.
Phase 2: Pilot Deployment & Feedback Loop (4-8 Weeks)
Launch a controlled pilot with a subset of users to gather real-world data and feedback. Refine data processing pipelines and ensure accurate trend generation. Optimize user interface for minimal burden and high compliance.
Phase 3: AI Model Refinement & Personalization (8-12 Weeks)
Enhance AI algorithms using collected pilot data for adaptive learning of individual patterns. Implement personalized feedback mechanisms based on corrected EB trends. Conduct A/B testing on coaching prompts and intervention strategies.
Phase 4: Full-Scale Integration & Continuous Improvement (Ongoing)
Integrate ENHANCE into the main AI coaching platform. Establish continuous monitoring for model performance and user engagement. Regular updates and feature expansions based on new research and user needs.
