Luckily, we live in the reality where every human who is interested in how their own body, and not the one of some random mouse, deals with blood sugar, can order a relatively inexpensive (for the benefits it provides) device — a continuous glucose monitor — and gather all the data they need to see what helps controlling the sugar level, and what does not. Using a CGM was a truly life changing experience for me, and I recommend trying it for everyone interested.
Which CGM did you get? Don't they require a prescription?
I’ve tried CGMs multiple times and didn’t have any life changing experiences.
I did have a couple low and high readings, but even with a food log and going back to re-eat the exact same meal I got completely different results.
I think the exercise induced changes that help regulate blood sugar aren’t going to show up on the time scale of ordering a couple CGMs. It has to be a sustained lifestyle choice.
