The average weight loss on the ND was approx 15% and that is the amount suggested by Professor Taylor.
There is no number of pounds given as everyone will be different weights. I would not pay a great deal of attention to your BMI if it is just based on your height + age + weight, since the important thing is your "personal fat threshold" and there is no way of quantifying that because again everyone is different.
When I started the ND I was not over weight and have never been considered obese, however I have obvious fat around my stomach. But that is not the important fat to get rid of, the fat in the liver and pancreas is what we need to get rid of and that happens at different rates. The fat in the liver goes quickly and its surprising how fast your liver function returns with regard to diabetes. But the pancreas takes longer which is why the diet is carried out over an 8 week period.
Will it work ? I don't know, but it has been great not feeling unwell and having BG readings like those of a non diabetic and on no medications for T2 at all when I was taking 9 tablets a day prior to the start of the diet.
Speak to your Dr or DN and give it a go you have nothing to lose. Good luck
