@dynomight@lemmy.world If you do run an experiment like this again, I’d recommend using a continuous glucose monitor (CGM). While they used to be prescription-only in the US, you can now buy the Dexcom Stelo or Abbott Lingo over the counter. Average blood glucose is not going to tell you much - more interesting is the blood glucose spikes after a meal and how quickly you return to baseline.
Did you have a look at Chris van Tulleken’s book Ultra-Processed People before the experiment?
I considered getting a CGM, but they all seemed to require all sorts of cloud services and apps and stuff that wouldn’t work for me.
I didn’t reap UPP, though I think I read this review: https://www.newyorker.com/magazine/2023/07/31/ultra-processed-people-chris-van-tulleken-book-review (should I?)
