> Vegetarians and vegans have lower T2D incidence on average FWIW.

Anecdotally, my dad tried vegetarianism for quite a while to address his T2D, but it had no effect. My mom cut out sugar and processed carbohydrates and her T2D was gone in ~3 months or so.

Following any diet is probably better than nothing at all, which could explain the lower incidence of T2D in that group vs the general public. I’d be more curious about the rates in vegetarians/vegans vs people who eat paleo or even carnivore.

Treating T2D and preventing T2D are completely different things from a dietary perspective. Same way you wouldn't give chemotherapy to a healthy person to prevent cancer

Then it is of no interest

There are studies that support it. Here is a meta analysis of low carb diets on T2D, the majority show it works, though as always, there is going to be some individual variability.
