Continuous Glucose Monitoring

Is there any actual data on the long term use of these devices in non-diabetics?

This feels like geek bait, imo. A nice simple metric to obsess over, and to optimise. With a super simple (therefore presumably wrong) biological model to back up it's worth.

It seems to be, that nothing particularly good has come of prior trends in quantified self-health (for regular consumers, pun intended, at least); and this seems to come packaged with a very real risk of orthorexia.

I think it's definitely geek-bait, I wore one for a few months and would say that unless you have diabetes/pre-diabetes it's a waste of time.

It is geek bait — most people read too far into these “spikes” and cut out healthy foods in doing so. It’s taking literally one metric as gospel which is moronic to be frank.

Yes, and elephant in the room - we already have very good measurements for diabetes risk that doctor's look at, A1C. It doesn't matter much how your glucose happens to be at a point in time because diabetes is a chronic condition that takes a very long time to develop, which is why doctor's aren't going to be looking at your glucose anyway.

You can obsess over your glucose all you want, but if you aren't lowering your A1C then you aren't lowering your risk.
