Saw another study mentioned in comments that had 24 hour glucose levels and there are definitely higher spikes for carb first for both T2 diabetics and people with a normal glucose response. One thing to note is that protein/veggies first didn't spike as much, but the glucose levels were also much slower to return to baseline. So I would call it a win, but not an absolute for T2 diabetics. It was a total win for people not glucose impaired.
