You will lose an incredible amount of weight, BUT I wouldn't recommend the diet for that. The ND was intended to help diabetics gain better control not as a weight loss plan. I Have a diary on here from when I did it, and I say in there, this is not a good idea for weight loss alone. Does your GP Know you are attempting this? Mine didn't initially but then I felt it right he should be in the loop and he looked after me throughout. My GP is really forward thinking, and knowing the ND was designed for diabetics, he was not 100% happy, but agreed to me doing it so long as I promised to stop if I ever felt ill. Luckily I didn't and I did it 'till the end. Please rethink this, there are liquid weight loss plans around such as the Cambridge diet etc, this is a diet for diabetics!
