Emmo; just to be clear; I haven't done the ND, but do appear to have reversed my T2 by breeching my personal fat threshold by losing some weight and significantly improving my insulin resistance.
I have been an avid follower of Professor Taylor and have corresponded with him, when I asked him some specific questions about my own condition.
If I could just comment:
I am always interested when I read of people commenting like the ND has a specific timeframe; almost like a course of antibiotics. According to Professor Taylor, the 8 week timeframe was for research purposes only. Clearly for research, there has to be a beginning, an end and certain measures along the way?
Clearly the tricky thing is knowing where each of our personal fat thresholds sit, and frankly, I have no idea where mine was, save to say I significantly trimmed back over a period of months.
I have no idea how close your 8 week target will take you to your desired weight, but, if you still have a way to go, and provided you remain healthy and feel well, there seems to be little clinical reasoning why you could not continue. Of course, assuming you are being supported by your Doc, you might want to discuss that with him/her if you fancy carrying on a bit longer.
One thing I will say is, once you get close to your target weight, whenever that is, start to plan how you will stabilise your weightloss, because it's often not as easy as it seems, to stop the loss. Anyone saying that to me a year or so ago, would have had me laughing in their face, but it took me some time to get the balance right, as I was almost paranoid that I didn't want to go into any form of yo-yo behaviour. In the end, it took me a number of months to get it right and another 4kg off. That left me a lighter than I planned, but I have remained there.
Good luck with it all. The potential rewards are worth the effort.
