Type 2 diabetes can be reversed with a low-calorie diet
...or you could not starve yourself on <900 calories a day and instead be a sane person and just eat low carb:

"Insulin therapy was reduced or eliminated in 94% of users; sulfonylureas were entirely eliminated in the CCI. No adverse events were attributed to the CCI."
Wow, that's pretty extraordinary, isn't it?  Every single person in the non-control group eliminated the need for sulfonylureatic compounds and a massive 94% reduced their insulin level or completely got off insulin altogether.  All with no adverse affects being recorded.You don't need to starve yourself or go on some ridiculous diet.  You just need to eat low carb and eat clean (a.k.a. "real" food) and your body will begin to heal in nearly every case.  I suspect the few test cases that didn't improve were so far gone they were too metabolically impaired to achieve any positive results.  The damage was likely too extensive and age possibly played a factor.  For everyone else, it appears they can get rid of diabetes...if they actually care enough to do so.
