What Over-the-Counter CGMs Mean for Fitness and Wellness Professionals

In March 2024, the FDA cleared the first over-the-counter continuous glucose monitor in the United States. The device was the Dexcom Stelo. Abbott Lingo followed shortly after. For the first time in the history of blood glucose monitoring, any adult could walk into a pharmacy and purchase a continuous glucose monitor without a prescription.

For fitness and wellness professionals, this event marks a before-and-after moment in the market. CGM data, which had previously been almost exclusively encountered in clinical settings, is now being generated by general wellness consumers and brought directly into gyms, physical therapy offices, health coaching sessions, chiropractic practices, and registered dietitian consultations. Understanding what this shift means for professional practice is not optional. It is necessary.

The Scale of the Shift

The numbers behind the CGM market expansion are significant. 38.4 million Americans live with diabetes, and another 96 million have prediabetes. (Centers for Disease Control and Prevention. National Diabetes Statistics Report. 2024.) These are the populations who have the clearest clinical motivation to wear a CGM. But the wellness market dramatically expands the addressable population.

CGMs have been adopted by athletes, biohackers, and health optimizers as tools for performance and longevity. Dexcom has partnered with Oura. Abbott has partnered with WHOOP. CGM data is being integrated into the wearable fitness platforms that millions of active adults already use. The population of people wearing continuous glucose monitors is no longer defined by a clinical diagnosis. It is defined by an interest in health data, and that population is the core client base of the fitness and wellness industry.

The practical result is straightforward: fitness and wellness professionals are encountering CGM data in their practices right now. The question is not whether this is happening. The question is whether the professional is prepared to respond.

Why Professionals Are Not Prepared

The professional training infrastructure has not kept pace with the market shift. Personal trainer certification programs, health coaching curricula, physical therapy education, chiropractic training, and registered dietitian preparation all predate the widespread consumer availability of CGM devices. None of them includes systematic CGM interpretation training as a standard component.

The result is a gap. Fitness and wellness professionals are encountering continuous glucose monitor data without a systematic framework to read it. They are guessing, avoiding, or googling, none of which serves clients well, and the last two of which represent significant missed professional opportunities.

This gap is not the fault of practitioners. It is a structural problem in the professional education market. No systematic CGM coaching framework built specifically for fitness and wellness professionals existed until the Glucose Pattern Recognition Methodology™ (GPRM™) was developed.

What Professional Preparedness Looks Like

Professional preparedness for the CGM-enabled client market is not about becoming a clinician. It is about having a systematic framework for pattern recognition that is grounded in established physiology, respects the professional scope of practice, and equips the professional with the language to have confident, accurate conversations about the data clients bring to their sessions.

That means knowing which glucose patterns are normal physiological responses to exercise, sleep, stress, and meal timing. It means knowing which patterns warrant documentation and ongoing monitoring. It means knowing which patterns indicate clinical concerns that require physician referral. And it means knowing exactly what to say in each situation.

Professionals with this framework are positioned to do something that is currently rare in the fitness and wellness industry: provide data-literate metabolic coaching that matches the quality of data clients are now generating. That is a significant professional differentiator.

The First-Mover Advantage

The CGM coaching market is in its very early stages. The mainstream consumer adoption curve for over-the-counter CGMs is just beginning. Professionals who build systematic CGM literacy now are entering the market before demand peaks. They are building expertise, reputation, and client base before the professionals who wait have begun.

In a market where a new professional category is being created, being early is everything. The certified specialists who complete training in 2026 will have a professional history with CGM coaching by the time it becomes a standard client expectation. The professionals who start training in 2028 will be starting from scratch in a market where established practitioners already exist.

Everyone has the data. Be the one who can read it.
