@gedankenstuecke, thanks for pointing me to this thread. It’s really exciting to see people interested in using CGMs to study what impacts their blood sugar. I’d love to participate as well.
I’ve got Type 2 diabetes and have recently gotten involved in more rigorous self-tracking and self-experimentation. I’m particularly interested in N>1 self-experiments to try to better understand person-to-person variations and be able to study interventions that are difficult to disentangle background in N=1 studies. Over on Reddit, I’m working with a group of diabetics studying the effect of hot showers on BG (protocol & preliminary). If any of you are interested in participating, we could really use data from some non-diabetics.
In terms of this thread, I agree that starting with food effects on glucose would be the easiest and quickest way to get useful data. I’m open to anything people want to try out, but one of the questions I’m most interested is the interaction effects between different macronutrients. There’s lots of small studies claiming that increasing fiber or fat in a meal slows glucose metabolism and reduces BG spikes, but they’re all observational, small sample sizes, and/or use fairly complex meals with lots of ingredients making it hard to be sure of what’s going on. I’d be interested in doing a study where we isolate the effects of consuming individual ingredients (e.g. pure sugar, protein isolate, oil), then mix and match to get a clean measure of the interaction effect.
Just a thought and as I said, I’m open to trying anything the group is interested in studying.
