Itake the word 'reverse' to mean you have got your BS readings in the normal range. And, hopefully, will remain so as long as you keep up your exercise and diet. But if you mean that reversing means curing.....then I feel that is impossible. If you stop exercising and start eating a normal diet (carbs with each meal) the figures will creep up. I have non-diabetic friends who practically live on junk food,. never eat veg, put sugar in their tea/coffee, a snack means a sandwich, and yet their BS figures remain normal - a diabetic who has reversed the figures can never hope for that
