Procedure

1. Initial Assessment and Screening

   • Use compute_bmi to calculate BMI and then compare against age-appropriate BMI percentiles (as per AAP/CDC guidelines for ages 2–18).
   • Use get_user_preferences to determine the user's developmental stage (early adolescence vs. young adulthood) and current level of parental involvement.
   • Ask the user about their perceived Health-Related Quality of Life (HRQoL) and goals beyond numeric weight loss.

2. Establish a Health-Centric Framework

   • Explicitly shift focus from numeric weight targets to "comprehensive health improvement."
   • Set primary goals around stabilizing BMI z-scores and improving energy, sleep, or mood.
   • Use update_preferences to document that the coaching priority is health behavior and lifestyle treatment (IHBLT) over strict weight-centric metrics.

3. Deploy Multicomponent Support

   • Physical Activity: Create or suggest a balanced activity plan using current workout tools.
   • Nutrition: Focus on nutritional quality and behavioral patterns rather than restrictive dieting.
   • Psychological Support: Use remember to log user motivations. Incorporate Motivational Interviewing (MI) or Acceptance and Commitment Therapy (ACT) principles in dialog to foster psychological flexibility.

4. Determine Developmental Coaching Path

   • Early Adolescents: Recommend high parental/family involvement. Use create_note to suggest family-based behavioral changes (e.g., shared meal environments).
   • Late Adolescents/Young Adults: Empower the user to take primary responsibility for decision-making. Shift to a technology-supported "maintenance" model as they age.

5. Integrated Digital Coaching & Feedback

   • Utilize render_suggestion_chips to offer modules based on ACT (e.g., "Manage Cravings with Mindfulness") or MI (e.g., "Identify Your 'Why'").
   • Use create_note or remember to track long-term adherence to habits.
   • Ensure regular check-ins to monitor for signs of eating disorder symptoms, though noting that evidence suggests IHBLT generally does not increase these risks.

6. Transition to Maintenance

   • For users who have reached health milestones, transition to "Weight Loss Maintenance" protocols prioritizing long-term adherence via technology-supported multicomponent coaching.
