I’m diabetic and manage it with a CGM and insulin pump (HbA1c at 6.8 after many years of struggles).

For convenience and my experiment, I eat practically the same meals at lunch every day, precisely weighed, always starting from very similar morning glucose levels, and strictly respecting timing and consistency.

I NEVER get the same response. Never. It’s an experiment I’ve been running on myself for a year. It’s useful for me, but for the diabetes team following me, “that’s not possible, there must be other factors, it doesn’t show, it’s the ‘CGM algorithm’” (a mystical object no one knows anything about, except that it’s supposedly intelligent).

This study is interesting. I hope this kind of information, this doubt, trickles down into the medical community. Even though I don’t have much hope. Maybe in years and years.

Would be interesting if a non-diabetic person does the same trial, as a "control".

Note: This is pure speculation, and I'm not claiming to know anything more than passing knowledge about diabetes.

Do you see any relation to physical exertion of the day before/after? What about mental signals, like "I'm going to be walking a bunch tomorrow"?

I am a developer and i work from home. In my experiment i ruled out “any kind of movement” :-D (no, i am not a bag of fat, only a lotto e “not in perfect shape”). But. I can confirm that lot of stress and lot of coffe have a big and misurable effect.

thanks for "misurable". i'll steal this wonderful combination of miserable and measurable, i see lots of use in devops for it... ;-)

I definitely see effects on my glucose the day after when I change my exercise routine, such as doing an extra LISS session. Anticipation of something stressful or exciting does also have an effect. I haven't noticed any effect from simply expecting more exercise later (without emotions attached). I believe a lot of this comes down to liver and muscle glycogen storage and release. (I'm T1)

I think the “experts” thought they knew but CGM is showing they really don’t know.

Sometimes my blood glucose will be high-ish like maybe 135. Then if I drink some coke, ie pure sugar, it causes my blood glucose to spike and then my insulin kicks in and it drives it back down to 110-120. It’s as if the switch to turn on the insulin wasn’t turned on because there was a slow steady creep up of blood glucose and then it needed to be woken up.

The body sure is strange but one thing I do know is that CGMs are changing things for sure.
