There is be a cliff, over which the damage is permanent. If you change habits soon enough, then we know many avoid it the permanent damage altogether. This is due to the beta cells in the pancreas; destroy to many, and go below a critical threshhold, then they don't seem to be repaired/regenerated enough forever more.

Thanks for your reply, that gives me something to take action for as currently I consume a lot of sugar in my day to day live.

After I ran into Dr Lustig's stuff which I found was also backed up by other pediatric endocrinologist, I cut out as much sugar and processed carbs as possible. Not as hard for me as I'm a meat and vegi kinda guy anyways. My thought was worst case avoiding sugar, processed carbs, and beer isn't going to be bad for you. Best case, avoid Type II diabetes.

Also following Lustig's advice on sugar and alcohol, make it count.
