ND is a very useful tool, and should get you there. I am too far gone along this pathway to benefit, so do not use it myself, but provided you do the maintenance phase properly, it should set you up for success. Your choice of Low Carb for follow on is sound IMHO. You should not hypo if not using medication (unless you starve yourself). Good hunting. Do not get too hung up on the weight loss target, since it is the clearing out of the excess fat that is needed, but you need to sit comfortably too. I lost more than the 15% but havr not got remission so it is not purely weight that does the trick.
