Roughly, the method used is the ketogenic diet. Very low carb, very high fat.

It might not necessarily be high in fat - it's probably the calorie restriction that works, as in this trial:

I mean the method used by Virta in this particular link. I am not suggesting that there are not other methods that work.

Personally, and anecdotally, I have tried calorie restriction dozens of times since childhood and it has never brought down my A1C.

It must be high fat. From the linked essay [1], the diet is 30g daily carbohydrates, 1.5g/Kg(body mass) protein. For an 80Kg individual, that results in 150*4=600Kcal. That means almost 2000Kcal in fat to reach the daily caloric intake.

Yep, and this is the method used by Virta Health. They are attempting to use this diet and telemedicine to reverse diabetes at scale. Their 2 year clinical data should be out soon.
