My blood sugar goes below 60 but I am not hypoglycemic and no, the alerts are not useful. And yes, the measurements are correct -- I have more than one way to measure blood sugar level.

Hypoglycemic means your body is dependant on sugar, can't get sugar and has adverse reaction to it.

My body can't get sugar, true, but is not dependant on it (fat adapted) and I have no reaction to it.

As I have not eaten any carbs for about two months any notion of hypoglycemia due to not eating sugar is a bit meaningless.

I know people who get much, much lower blood sugar levels and feel fine. The levels they get would (below 40? below 30?) would be lethal to "normal" person, if sugar addiction can be called normal at all. But they all feel fine and are probably healthier than most.

I put CGM on my arm to learn how my blood sugar levels look when on my diet and then what happens when I switch carbs back on -- I expect my body to "freak out" a little bit and then stabilise within couple of days and that's what I would like to see in a bit clearer detail using my CGM.

As to driving the prices down... nah, I am not making a dent. These devices are too expensive to use regularly even for me (software devs salary). I will just put a couple of them to learn a bit about myself and then stop when I got what I needed.

Very interesting experiments as a data nerd would love to see a write up about how your diet effected your sugar. I know it's unlikely you will publish it but if you would I'd love to read it.

It is interesting but my data is useless. I lost over 70 pounds since July last year but I don't have any good record of blood sugar measurements. I did measurements whenever I liked either to confirm I am in ketosis or just to check my blood sugar / ketone levels in response to how I felt or to check how much various meals raised my sugar. But I did not keep any log.

There is couple things I learned. When you are on a strict ketogenic diet your blood sugar pretty much stays the same throughout the day. Even if I eat one huge meal for entire day, my sugar after the meal is pretty much the same as before the meal or within 10mg/dL. My exercise and circadian rhythm affect sugar more than meals.

Given this I wonder if it is possible at least for some people with diabetes to skip carbs completely and live carb-free but also insulin-free life.

Another thing I learned is that as I started my first keto month, your blood sugar starts dropping, then goes back up after about two weeks. Coincidentally, I also felt pretty poorly for those two weeks and my running performance dropped dramatically until my body adapted. The second time I started keto (after two months of break from it) I have seen nothing of the sort. Actually, I feel (but don't have good enough record to be sure) my blood sugar got a bit higher. But I have only been doing regular sugar measurements when I was in keto so I don't have data for sure.
