"enthusiasm of some people with Type 2 diabetes to take major steps to escape from diabetes became clear in the very large-scale email feedback [5]. The email feedback from those who lost weight and returned to normal glucose tolerance, showed that duration of normal glucose control in some now approaches 3 years [18]. Provided that weight loss is maintained, diabetes does not return, at least over several years."Unfortunately many of us can testify that getting the right off, and keeping it off are not always possible. Our bodies are not machines, and do odd things sometimes.

Also the new study whose formal results are to be published in Dec shows that 100% participants have now passed the 1 year line (on aug 17th 2017) However these people had support with their maintenance diet from the survey organisers.
