Whether Diabetes is reversible depends upon your outlook.
I feel that being diagnosed with Type 2 Diabetes, and gaining remission from high Blood Glucose through a Low Carb way of eating is the best thing that ever happened to my health! - Just the possibility of daily injections, of blindness, of amputations, of diabetic coma, made me take my health much more seriously.
So the thought of being condemned for the rest of my long healthy life, to eat delicious food which I know (from my BG meter and regular GP blood tests) is good for me, just fills me with joy!
I have no idea what sort of book would be suitable for you. I learned all I know about diabetes from this forum, Dr David Unwin GP, his wife Dr Jen Unwin ( a Psychologist) and other members of the Low Carb 'community' on Twitter. She has written a book called 'A Fork in the Road' about diabetes, carbs and carb addiction but I didn't feel the need to read it.
