[OUR VERDICT]

Dexcom Stelo wins for serious metabolic optimization with superior accuracy and AI insights, while Abbott Lingo excels for budget-conscious beginners.

After extensive real-world testing by health professionals and consumers, both CGMs offer compelling but distinct value propositions for metabolic wellness tracking. The Dexcom Stelo emerges as the superior choice for users serious about comprehensive metabolic health optimization, particularly those who want seamless healthcare integration and AI-powered insights.

Stelo's key advantages include its longer 15-day sensor life, superior accuracy rating of 9.2% MARD, and robust AI integration through Google Cloud's Vertex AI platform. The healthcare provider integration via Dexcom Clarity is particularly valuable for users working with medical professionals on metabolic health. The device's spike alerts and real-time notifications provide actionable feedback without requiring constant app monitoring.

However, Abbott Lingo wins on accessibility and flexibility. At $49 for a two-week trial, it offers the lowest barrier to entry for CGM newcomers. The minute-by-minute readings provide more granular data than Stelo's 5-minute intervals, and the flexible purchasing options (no subscription required) appeal to intermittent users who don't want continuous monitoring.

For most BodyOS users focused on serious metabolic optimization, Dexcom Stelo's combination of accuracy, AI insights, and healthcare integration justifies the higher price point. However, budget-conscious users or those wanting to try CGM technology should start with Abbott Lingo's affordable entry point.
