Can't the pancreas recover to produce healthy (or something below healthy yet essentially sufficient) amounts of insulin once you beat insulin resistance? Can't lipoic acid (which does the job of pushing energy into cells that is normally done by insulin AFAIK) combined with a suitable diet be used after the described procedure to decrease need in insulin below what is considered a norm to relieve overloaded pancreas and help it regenerate?
