i found out about 8 years ago that i was type 2, was prescribed 2-500mg metformins a day, i went on a diet and lost about 45lbs. i have gained back about 20lbs but i am no longer on metformin, i am able to control it through exercise, not my diet- because my diet sucks. the risk i am taking is that if for some reason i am no longer able to exercise then i will either have to change my diet or i will end up back on medication. i do not believe there is a cure for it or that it is reversible, i think there are ways to control it but if you go back to being overweight and eating a diet that is overloaded with sugar you will be back in the same shape you were in before. this is just my opinion, i hope to never find out whether that is true or not.
