My feeling is that T2 is an umbrella term for a number of very different but related conditions, including some with a significant genetic component, some powered very much by weight gain (general or visceral/TOFI), some characterised by insulin resistance, others which progress and various complex combinations of these and still other components!
So really I would say it depends on quite which subset of T2 you happen to have whether or not you can put your T2 into remission, reversal and whether or not it will continue to progress over time.
