Using CGM in Clinical Practice
Start incorporating continuous glucose monitors into your clinical toolbox
Professional training for continuous glucose monitor use now available!
But aren’t CGMs only for people with diabetes on insulin?
Not anymore. I’m in this business to PREVENT chronic disease. Are you with me?
In the same way doctors prescribe metformin off-label for prediabetes, they can prescribe a CGM off-label for their patient anytime they like. Their insurance may or may not cover it. Their patients can get much-needed information about how their food choices impact them in real time. Combining that with professional support/education and 4-weeks can be enough to move the needle and cost less than $100 out of pocket per month (without insurance).
Of course, now we can also make use of the over-the-counter CGMs available on the market! This can make things so much easier, but also make it hard to choose.
Because of the growing OTC market for CGMs, all our patients are buying them and coming to us to help interpret their data. That’s why I’m here…. to help you feel like an expert.

Elevate Your Metabolic Health Practice with the "CGM User Manual"
Are your patients struggling to make sense of their CGM data—and are you running out of clinical time to interpret it for them?
This is the manual your practice needs: A step-by-step guide that empowers your patients to decode the bulk of their own data, with your help, understand their glucotype (one of 6 metabolic patterns), and support your work of providing empowered, personalized care.
By "prescribing" Hack Your Blood Sugar, you save hours of clinical time spent on tech troubleshooting and basic interpretation, allowing you to focus on high-level clinical strategy and long-term patient outcomes.
How does Hack Your Blood Sugar help you and your patients?
-
Yes. We provide tiered pricing for bulk orders (10+ copies) for practitioners who wish to include the book in their "New Patient" onboarding kits or as part of a structured weight loss or metabolic health package. Head over to our Bulk Orders page.
-
Many patients feel overwhelmed by the "noise" of real-time data. This book provides a "Noise-Canceling Diet" protocol and a Pattern Recognition Guide. It teaches patients how to distinguish between a "normal" post-prandial rise and a metabolic spike, reducing the number of urgent, confused emails to your office.
-
The book categorizes metabolic responses into six distinct "Glucotypes." For you, this acts as a diagnostic shortcut. Instead of reviewing hundreds of individual data points, you can use the patient’s identified Glucotype (e.g., "The Spike-and-Crash" vs. "The Slow Burn") to quickly tailor their macronutrient ratios and lifestyle interventions. It provides a common language for you and your patient to discuss their unique bio-individuality.
-
Many metabolic health programs cost upwards of $4,000–$5,000 per year, which is a barrier for the average patient. Hack Your Blood Sugar teaches patients how to achieve those same results—including data analysis and personalized planning—for roughly the price of a single CGM sensor (~$200 for a 90-day DIY cycle). This allows you to offer high-level metabolic tracking to a much broader segment of your patient population without the prohibitive overhead. It also shows how to phenotype your patient with less expensive metrics.
-
Yes. The 90-day framework is divided into actionable phases: Understanding the Tech, The Discovery Phase (Testing), and The Implementation Phase. It serves as an ideal "textbook" for health coaches, chiropractors, and nutritionists running 8-week or 12-week metabolic reset groups.

Get results!
The data can only get you so far. By combining the CGM data with your expert guidance, your patients can use a CGM for as little as 4 weeks and develop a personalized plan that gets them rapid results.
There is no cumbersome food logging. Using the FreeStyle Libre or Dexcom Stelo system, patients add free notes about their meal, exercise, sleep, or stress, and you can review their data anytime as they share it with you 24/7 on a free app.
It’s better than a diet diary. You can’t hide from a CGM.
Patients auto-adjust and make their own changes in response to real-time data.
Patients come to your appointment with burning questions and insights about their data making your coaching relationship more fruitful.
The data allows you to assist in more evidence-based medication adjustments (up or down) as metabolism shifts.

I think all dietetic and nutrition professional should have this in their toolbox.
Like you, I’ve been interested in using CGM in my practice for years. When I first looked into it, I found there were no learning resources outside of the diabetes clinic.
It took me months of talking with Abbott’s customer service, talking with my own doctor (who kindly wrote me a prescription), watching YouTube videos and lurking on Facebook groups for diabetes to learn how to get one, optimize its use, interpret data and then learn how to manipulate my levels.
The last part was easy. We have been well-trained on what helps blood sugar levels. However, nothing really prepared me for seeing the effects with my own eyes.
Anyway, I started using this with my patients and created detailed instructions complete with pdfs and instruction videos on how to obtain, install and use a continuous glucose monitor to make it easy for my patients. Now I’m making these instructions available for you so that YOUR patients can get started too.
You could be a dietitian, health coach, chiropractor, nurse practitioner or ND. This is a tool you and your patients are going to love.

FREQUENTLY ASKED QUESTIONS
-
I provide patients with a letter for their doctor describing our work along with the prescription code for the device I recommend. There are other ways to get a CGM too like online pharmacies.
-
It might! But as you know, it varies all over the place. I always try to loop their doctor in to get help on that. But if just using it for 1-3 months, paying cash might be fine. The cash price should be about $ 40-75/2 weeks of use. Remember, you need a PRESCRIPTION, not insurance coverage. However, after doctors see how well this works for people, I’ve seen them go to bat for their patients and code the prescription in a way that gets partial or full coverage for people who don’t have diabetes. So let’s just get the ball rolling.
-
You have a few choices. You can write a letter on their behalf, as this is the least expensive route. But there are over-the-counter CGMs available now that are great. We discuss the Dexcom Stelo in our CGM Interpretation Webinar series.
-
You can use either one! I recommend the Libre 3. Both are eligible for the Free Trial from Abbott’s website (get one free sensor.)
-
I support all of them. It depends on the person, insurance, etc. The Dexcom is excellent and is covered by insurance often for patients with diabetes. But without insurance, it’s the most expensive. I prefer the FreeStyle Libre 3 as it has good accuracy, has a more reasonable price tag if they can get a prescription. Without a prescription, the new Dexcom Stelo is available over-the-counter.
-
Yes! The Dexcom Stelo is out and it's going to be great for non-prescribers like nutritionists, dietitians, and health coaches. We discuss it in our webinar series.
