There is a continuous dribble of results from Extreme Diet, lap band, bariatric surgey and small intestine liner that suggest very clearly that hauling back on calories/energy body can absorm from gut have dramatic results on BG and on going body health. While I believe that the word "cure" "remission"; reversal may be over optimistic, my own results achieved independently with my Doctor's help did in fact:

a) get liver leak - over generation of glucose stopped.
b) hearty exercise gets the BG down when all else fails.
c) after being on 1200 calorie diet for 6 months and walking 1 to 2 miles, I suddenly had to remove Starlix and 26 units of 75/25 insulin once a day as my own insulin either returned and/or insulin dropped and the external insulin was not needed. A1c progression 13.3 to 6.9 to now 6.4.

The last study I read and attached suggested what I felt was in my case - after years going nowhere on a unworking treatment and my pancrease should be shot; I routinely today see my meal bolus from my pancreas on my BG at linch and dinner where I wait to inject the small 4 unit boost of Humalog Lispro after digestion starts up glucose output.

I attach the study.
