So I think this is an attempt to link a random result to a metabolic disease? This goes against the advice of pretty much every health doctor, nutritionist, and scientist.
I would be shocked if there aren’t more studies using CGMs to track diet adherence and health in the next few years.
If your doctor is telling you that prolonged periods of high blood sugar sustained over time are good for you, I would suggest that they review a bit of the literature.
If I asked my doctor about using a CGM as a runner that likes to eat fruits and vegetables he would look at me like I'm an idiot.
I imagine he would say, "So you aren't having any health issues and bought this $100 device anyway?"
People who get pre-diabetes or diabetes (type 2), well, it's usually because they are overweight or obese. There's just not a lot of people getting diabetes in a mysterious way.
Also, saturated fat is linked to diabetes. And cutting that out improves heart health anyway.
