I was gifted a Lingo biosensor this summer, and as a dietitian, I was admittedly fascinated by getting a peek at what my glucose was doing throughout the day.
But one of my biggest takeaways?
A CGM gives you data. It doesn’t always give you the explanation.
This was one of the more interesting days I captured.
That morning I did my usual strength workout, ate breakfast, and then my son asked me to go for a run with him. So we headed out for a few miles.
When I looked at my graph afterward, my glucose had stayed a little higher than my typical morning pattern for longer than I expected.
Was it breakfast?
The strength workout?
The run?
Stress hormones signaling my liver to release more glucose so my muscles had plenty of fuel available?
Probably some combination of all of it.
And that’s the part I think is worth understanding.
Food is only one thing influencing the squiggly line on a CGM. Exercise, sleep, stress, hormones, hydration, timing and even the sensor itself can influence what we see.
And a rise in glucose isn’t inherently bad.
During exercise, making more glucose available can be exactly what the body is supposed to do. Your muscles are asking for energy, and your body responds.
This graph also wasn’t showing concerningly high glucose. What interested me was simply that the pattern was different from what I typically saw.
And maybe that was my biggest lesson from wearing a CGM:
The goal isn’t to create the flattest glucose line possible. It’s to understand that our bodies are dynamic, responsive and constantly adapting to what we’re asking of them.
So if you’re curious about wearing a CGM, enjoy the data.
Just don’t let every little hill in the graph convince you there’s a fire. 🔥
And if you’re curious about trying one yourself: My Lingo biosensor was gifted to me, and they also gave me a 15% discount code to share with you. You can use LNGHCP3 for 15% off at Hello Lingo.
I enjoyed having a window into my own glucose patterns, but remember: the data is only one piece of the story, and a perfectly flat glucose line isn’t the goal.
