Dexcom, best known for continuous glucose monitors used by people with diabetes, announced on February 4, 2026 that its over-the-counter biosensor Stelo is getting a significant AI upgrade focused on food logging and behavioral nutrition coaching — a sign that glucose-tracking technology is moving deeper into mainstream wellness rather than staying confined to diabetes management.
Dexcom built its business over two decades supplying prescription continuous glucose monitors to people with type 1 and type 2 diabetes, and the company’s clinical credibility in that market is a large part of why Stelo’s move into general wellness carries more weight than a typical consumer nutrition app. Rather than launching a glucose-adjacent wellness product from scratch, Dexcom is extending an existing regulatory relationship with the FDA and an established manufacturing and sensor supply chain into a much larger addressable market of health-conscious consumers who don’t have diabetes.
The ambassador choice of Mike Golic Sr. also signals where Dexcom sees its next growth audience: not people managing a diagnosed condition, but sports-and-fitness-minded consumers who might never have considered a glucose sensor relevant to them. That marketing strategy mirrors how Whoop and Oura built their early user bases around athletes and performance-minded early adopters before expanding into broader wellness marketing, suggesting Dexcom is following a similar playbook to grow Stelo’s non-diabetic customer base.
What Stelo added
The centerpiece of the update, called Enhanced Smart Food Logging, lets users log meals through text search, barcode scanning, or photo capture, drawing on a nutrition database of more than one million food options to estimate calories, carbohydrates, protein, fat, dietary fiber, and other macronutrients. A redesigned Daily Insights feature uses a card-based interface to deliver three personalized recommendations each day, built to connect a user’s meals, activity, and sleep to their glucose trends rather than presenting numbers in isolation.
Who’s behind it and why
Girish Naganathan, Dexcom’s Executive Vice President and Chief Technology Officer, said the update is meant to “eliminate nutrition tracking friction so users can make informed, health-conscious decisions.” Notably, the company’s marketing for Stelo has also enlisted Mike Golic Sr., the former NFL defensive tackle and sports broadcaster, as an ambassador — part of a push to position continuous glucose monitoring as a mainstream fitness and wellness tool rather than a medical device reserved for people with diagnosed diabetes.
Context: CGMs go mainstream
Stelo was the first over-the-counter continuous glucose biosensor cleared by the FDA, opening glucose monitoring to people without diabetes who want to understand how food and exercise affect their blood sugar in real time. Dexcom’s push into AI-assisted meal logging follows a similar trajectory to Oura’s GLP-1 Insights and Whoop’s broader health-platform ambitions: wearable and biosensor makers are converging on the same idea, that glucose, sleep, and activity data are more useful to consumers when an AI layer translates them into plain-language daily guidance rather than raw charts.
The evidence gap
Dexcom has said that after 30 days of use, a majority of Stelo users report positive changes in dietary and eating patterns, based on the company’s own data rather than an independent peer-reviewed study. That distinction matters: unlike Dexcom’s prescription CGMs, which have extensive clinical literature behind their use in diabetes care, the metabolic benefit of glucose-based nutrition coaching for people without diabetes is less thoroughly studied, and some endocrinologists have cautioned that normal, harmless glucose fluctuations after meals can be misread by healthy users as problems requiring intervention.
What’s next
Dexcom said the nationwide rollout of the enhanced food-logging features across iOS and Android was set to happen within weeks of the February announcement, with a more thoroughly redesigned Stelo app planned for later in 2026. As GLP-1 medications reshape consumer interest in metabolic health, Dexcom’s bet is that pairing its established glucose-sensing hardware with AI-driven nutrition coaching can capture a wellness-focused customer base well beyond its traditional diabetes market — putting it in more direct competition with wearable and app-based nutrition tools like Noom and MyFitnessPal’s newly acquired Cal AI technology. For consumers, the rollout means a familiar medical-device brand is now competing on the same AI nutrition-coaching turf as apps built from the ground up for general wellness, a convergence likely to accelerate as more companies chase the growing GLP-1-adjacent health market.
