my personal suggestion eat healthy foods that does not require much insulin secreted or injected, and let your body heal. which foods are healthy I wont mention because people just want bread, ice cream, and take a pill or inject insulin and think the sugar they ingest is magically disappearing, well its not. Metformin is helpful, but if people rely on it as an eternal crutch thinking its going to solve the reason diabetes develops in the first place, well it solves it so perfectly that. pill becomes 2, 2 > 4, 4>insulin and people are just getting worse. if excess of sugar is the problem how about not keep eating it for some time, again dont remove it overnight cause it will do more damage than good, hard to suggest people to be vegeterians with very little meat consumption, eat nice fats, when all they want is eat sugar and take a pill. good luck.
