 WHO issued conditional recommendations (not full endorsements) for GLP-1s in obesity treatment, explicitly acknowledging 'limited long-term evidence.' The conditional framing signals institutional uncertainty about durability of outcomes and cost-effectiveness at population scale. WHO requires countries to 'consider local cost-effectiveness, budget impact, and ethical implications' before adoption, suggesting the chronic use economics remain unproven for resource-constrained health systems.

+Danish cohort achieved same weight loss outcomes (16.7% at 64 weeks) using HALF the typical semaglutide dose when paired with digital behavioral support, matching clinical trial results at 50% drug cost. If this half-dose protocol proves generalizable, it could fundamentally alter the inflationary cost trajectory by reducing per-patient drug spending while maintaining efficacy.

 The discontinuation problem is worse than just lost metabolic benefits - it creates a body composition trap. Patients who discontinue lose 15-40% of weight as lean mass during treatment, then regain weight preferentially as fat without muscle recovery. This means the most common outcome (discontinuation) leaves patients with WORSE body composition than baseline: same or higher fat, less muscle, higher disability risk. Weight cycling on GLP-1s is not neutral - it's actively harmful.

+Digital behavioral support may partially solve the persistence problem: UK study showed 11.53% weight loss with engagement vs 8% without at 5 months, suggesting the adherence paradox has a behavioral solution component. However, high withdrawal rates in non-engaged groups suggest this requires active participation, not passive app access.

 PRIMARY CONNECTION: GLP-1 cost-effectiveness under capitation requires solving the adherence paradox (March 12 claim candidate)
 WHY ARCHIVED: Convergent evidence that digital behavioral support partially solves the GLP-1 adherence problem — changes the economic model under capitation if sustained
 EXTRACTION HINT: Focus on the half-dose finding (cost efficiency) and the convergence with WHO guidelines (behavioral combination is now international standard). Scope carefully — observational, not RCT.

+- Voy platform components include live group video coaching, text-based support, educational content, weight monitoring, and adherence tracking
+- UK Voy study showed high withdrawal rate in non-engaged group limiting generalizability
+- Tirzepatide users outperformed semaglutide users: 13.9% vs 9.5% at 5 months in Voy cohort
+- WHO December 2025 guidelines recommend combining GLP-1 with intensive behavioral therapy
+- Danish study was 64 weeks duration, UK Voy study was 5 months
+- All three studies (UK, Danish, Wiley) were retrospective/observational, not RCTs
