Thanks @JessicaK! That makes sense, if you’re tracking something granular like that, it does make a lot more sense! I used a CGM when I had gestational diabetes last year, but mainly just as a rapid feedback mechanism to learn which foods were “safe”. I never exported the data.
So… my experiment still isn’t started. A couple reasons…
- I fell off track on food tracking entirely, whoops
- I really want to try the one-button tracker. In fact, I used it for a day, and the experience of it was interesting! But it’s actually a bit broken. @jakobeglarsen guessed the GPS chip wasn’t connected, so I opened it up – yup, a loose wire. He showed me where it should go, and I’ve ordered a soldering iron.
- I’m also really interested in logging data via self-survey, and in particular want to try setting something up using MindLogger. Anisha Keshavan shared an example on how to do this (an example “hangry” survey, haha), and I still want to try setting something up!
Maybe next week. 
I’m enjoying exploring tools.
