Yehbutnonut Some people claim to have reversed T2 diabetes, but they haven't. What they have done is changed their lifestyle, so that the condition is well-managed without medication. If the person were to return to normal eating and exercise, the condition would return. It is not reversed.
I have had T2 diabetes for over 30 years. I'm not, and never have been, obese, nor have I ever pigged out on junk food. Nobody really knows why I developed it. I have taken part in a number of studies and my condition is well-managed, but it will never be reversed. If I eat a piece of cake, my blood sugar goes through the roof. Eventually, the level will come down, but if I were to eat more than one piece of cake (or sweets, etc) more than once in a blue moon, I'd be in trouble. I haven't eaten bread, pasta, potatoes, pastry, rice or most fruit for years, but my condition is still deteriorating. I'm finding it increasingly difficult to walk, I have permanent pain in my hands and feet, I'm often debilitatingly tired and my eyes need to be checked every three months because I'll very probably go blind.
