Adherence
AI-powered virtual health coaches (e.g., chatbots like Paola) combined with wearables can significantly improve physical activity, dietary adherence, and reduce weight and waist circumference in inactive adults aged 45-75.
For adults over 45 who are inactive, using an AI-powered health app with a wearable tracker can significantly boost physical activity and improve diet. Look for programs that offer a chatbot for guidance and track your activity automatically. This approach can lead to modest but meaningful weight loss and waist reduction without needing intensive in-person counseling.
Participants increased their weekly physical activity by an average of 109.8 min, improved Mediterranean diet scores by 5.7 points, lost 1.3 kg in weight, and reduced waist circumference by 2.1 cm... The study demonstrated excellent feasibility, with high recruitment rates, 90% retention, and no adverse events.
Why this rating
Based on a 12-week proof-of-concept study with a specific age group (45-75) and inactive adults; feasibility was high but sample size and duration are limited.

- AI-driven behavioral weight loss (BWL) interventions using reinforcement learning can achieve weight loss outcomes (approx. 7%) comparable to intensive human coaching but with significantly reduced contact hours (one-third the coaching time).Moderate
- Mobile health (mHealth) applications and wearable technology can lead to modest reductions in body weight and BMI, but long-term benefits may diminish once device usage stops, suggesting the Hawthorne effect or need for continuous engagement.Moderate
