Measuring Metabolic Health with a Continuous Glucose Monitor
By Dee Davidson, FDN-P | Confidently Love Yourself™
Continuous Glucose Monitors (CGMs) are becoming one of the most powerful wellness tools available today. You’ve probably seen people wearing them — small patches on the arm or abdomen — and may have wondered, “Should I be tracking my blood sugar too?”
The answer is: quite possibly, yes.
Even if you’re not diabetic, your blood sugar stability plays a huge role in your energy, hormones, weight, mood, sleep, and longevity.
In this article, we’ll explore why metabolic health matters, the signs of imbalance, the incredible insights CGMs provide, and why my preferred tool for clients — the Theia Health CGM — is changing the game.
Why Non-Diabetics Need Continuous Glucose Monitoring
Metabolic health means your body can digest food efficiently, manage blood sugar without extreme spikes or crashes, and maintain balanced cholesterol, blood pressure, and waist circumference — all without medication.
When that balance slips, even slightly, it creates stress throughout the body. Spikes in blood sugar and insulin can trigger:
Fatigue and afternoon crashes
Brain fog and poor focus
Weight gain (especially belly fat)
Hormonal imbalance (perimenopause, PCOS, adrenal fatigue)
Sugar cravings and mood swings
Sleep disturbances and nighttime waking
Chronic inflammation
Unfortunately, only about 1 in 8 adults in the U.S. have optimal metabolic health — meaning most of us have no idea how our blood sugar fluctuates day to day.
That’s where continuous glucose monitoring comes in.
What Is a Continuous Glucose Monitor (CGM)?
A CGM is a small, wearable device that measures your blood glucose in real time, 24/7. It gives you a window into how your food, stress, sleep, and exercise affect your body’s blood sugar — something a traditional lab test could never capture.
The sensor sits just under your skin (typically on the back of your arm), continuously tracking your glucose levels and sending the data to your phone. You can see spikes, dips, and recovery trends throughout your day — in real time.
This helps you connect the dots:
Which foods keep you stable (and which ones don’t)
How poor sleep or stress affects your blood sugar
How movement, hydration, and timing impact metabolism
No more guessing. You finally get to see the full picture.
Benefits of Using a CGM
Real-time tracking of your blood sugar trends
Personalized nutrition insights — how your body responds to food
Better energy, focus, and sleep
Hormone and weight balance by stabilizing glucose swings
Motivation and accountability — you’ll see instant feedback when you make changes
No finger pricks, no pain, and no confusion
CGMs were once only for diabetics, but today they’re an incredible tool for anyone looking to optimize health, longevity, and performance.
Introducing Theia Health CGM
When it comes to tracking metabolic health, my go-to recommendation is the Theia Health CGM.
This small, sleek, FDA-certified device uses the FreeStyle Libre 2 sensor — it’s painless to apply, waterproof, and discreet (about the size of two stacked quarters).
What I love most:
You can order it yourself (no prescription hoops)
It syncs seamlessly with your phone
It’s affordable and HSA/FSA eligible
The platform includes easy-to-read charts and personalized insights
Most importantly, Theia gives my clients the data they need to take ownership of their health — to see what’s really happening behind symptoms like fatigue, bloating, weight changes, and cravings.
It’s the perfect starting point for building awareness and creating real, sustainable change.
