I think other surveys have gathered data on T2D. The PLRC survey asked about it as a pre-existing condition though the data is not really that useful because of the way the survey was designed.

I’m not sure if ozempic is popular among LC patients, although I suppose it sees a lot of use nowadays.
I’m curious… have you tried any dietary interventions for T2D? Zerocarb diets like carnivore have been tried to treat it. Calorie restriction also works (can be high carb), although apparently it’s unpleasant. That is what’s been reported in the literature anyways. The Paleomedicine group / Zsofia Clemens publishes on a carnivore diet variation, the paleo ketogenic diet. They report success for T2D and T1D. Some more T1D info here.
NOTE: people report negative experiences with the carnivore diet. see some safety information here: Meat only diet - Long Haul Wiki
Data on carnivore from a Harvard survey https://doi.org/10.1093/cdn/nzab133 :
- Of 13 participants reporting insulin use for type 2 diabetes, all but 1 person reported discontinuing insulin use.
- 3 participants with type 1 diabetes report discontinuing insulin use.
These are all people who stuck with the diet for more than 6 months, so these are presumably survey responses from diet responders.
