I, in no way, endorse this procedure but it does have some bearing on Abrupt T2. It was orignally thought that much of the gains from this surgery was due to the limiting of / and types of food that people could eat once this surgery was performed. The citation below, however, shows that, in this case, there are far ranging effects on the hypothalamus that suddenly take effect. These effects proceed weight loss and involve the whole series of hormones that influence metabolism.
My point for Abrupt T2 is that this shows that the hypothalamus is a higher order mechanism that can certainly effect, if not control, the whole insulin cycle. Once again, there is no change in the underlying beta cell structure. The change isn't there but higher up.
