What Is BioFit? An Introduction to the Glucose Pattern Recognition Methodology™

BioFit is a professional certification and education company that trains fitness and wellness professionals to interpret their clients' continuous glucose monitor (CGM) data. BioFit's proprietary framework, the Glucose Pattern Recognition Methodology™ (GPRM™), organizes CGM data into a structured system of pattern categories, giving coaches a systematic way to observe, understand, and act on the metabolic signals their clients are already generating.

BioFit was founded by Amanda Davis, a NASA Certified Payload Operations Controller for the International Space Station at Marshall Space Flight Center, and a CGM user for over 20 years. Amanda spent her NASA career learning to read complex data streams and identify the pattern inside the noise. She has spent decades doing the same thing with her own glucose data. BioFit exists because she noticed something: fitness and wellness professionals were encountering CGM data in their practices every week, and almost none of them had been taught how to read it.

Why CGM Data Reached Fitness Professionals Before Anyone Trained Them to Read It

The shift happened quickly. In March 2024, the FDA cleared the first over-the-counter continuous glucose monitor for marketing, opening glucose data to anyone over 18 who wanted it, not just people with diagnosed diabetes.1 Since then, the over-the-counter CGM market has grown at a projected annual rate of nearly 17%, driven largely by health-conscious, non-diabetic consumers using the devices for general wellness and performance insight.2 Those consumers are personal training clients, health coaching clients, and patients sitting in physical therapy, chiropractic, and dietitian offices right now.

The professionals working with them did not train for this. Personal trainers, health coaches, physical therapists, chiropractors, and registered dietitians all have deep expertise in their own scope of practice, but glucose pattern interpretation was never part of any of those curricula. That gap is what BioFit was built to close.

What the Glucose Pattern Recognition Methodology™ Is

The Glucose Pattern Recognition Methodology™ (GPRM™) is a systematic framework, developed by Amanda Davis, that organizes CGM data into distinct pattern categories, each with its own coaching application and scope-of-practice boundary. Rather than treating a CGM graph as a single number to react to, the GPRM™ teaches professionals to recognize recurring, physiologically grounded patterns, how a client's glucose responds to a meal, a workout, a night of poor sleep, or a stressful week, and to coach accordingly.

Every pattern in the GPRM™ is classified by evidence strength, so a Certified BioFit Specialist™ knows precisely how confidently to speak about what the data shows. Some patterns are strongly supported by peer-reviewed research and can be coached with confidence. Others are physiologically sound but still developing in the research literature, and are presented to clients with appropriate nuance. A defined subset of patterns fall outside coaching scope entirely, these are Recognize and Refer patterns, where the specialist's job is to document what the data shows and refer the client to a physician, not to intervene.

Who BioFit Trains

BioFit's curriculum is built for five professional types, all in private practice, who are actively encountering CGM data in their work but were never trained to interpret it:

• Personal trainers, who see glucose response show up in a client's training capacity and recovery

• Health coaches, who need a defined scope for discussing glucose data without practicing medicine

• Physical therapists, who see metabolic patterns intersect with pain, inflammation, and rehab outcomes

• Chiropractors, who are often the first practitioner to see a client regularly and notice metabolic red flags

• Registered dietitians, who already work with nutrition data and can extend that expertise into real-time glucose response

Every part of the BioFit curriculum is scope-differentiated across these five professions, because what a personal trainer is permitted to say to a client about a glucose pattern is not the same as what a registered dietitian is permitted to say.

The Certified BioFit Specialist™ Program

The Certified BioFit Specialist™ (CBS™) is BioFit's flagship credential, a live cohort-based program that trains professionals to apply the GPRM™ inside their own scope of practice, with a decision-making framework for when a pattern is coachable and when it requires physician referral. Graduates leave able to say, with real professional grounding, “I read, and understand, the data.”

Why It Matters Now

Nearly 130 million U.S. adults are living with diabetes or prediabetes.3 A large share of them will never see an endocrinologist regularly, and an increasing number of metabolically healthy people are wearing a CGM simply to understand their own bodies better. Fitness and wellness professionals are the ones spending the most consistent, hands-on time with these clients. BioFit's premise is simple: everyone has the data. BioFit trains the professionals who are in the room to be the ones who can read it.
