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.
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.
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.
