I think that the word "cured" is being used as many of the type 2 diabetes patients did not need any medication any longer. Not needing medication means that you are cured, is the line of thinking. That is what the colourful bar chart in the quoted study shows.I'm not sure about the word "cure" though. Even though insulin sensitivity may be heightened, I'm not sure it gets backs to a level that would indicate cured. If a person were to do this for a year and the do a glucose test and be back to normal within 2 to 3 hours, I would agree that they had been cured. Is there any info about that? --This seems to be more about controlling glucose and improving to be sure.
