I agree with Mouseclick,
but I think you will find that even type 1 Diabetes is corrected by a raw food diet, but this has to be an exclusive diet of raw vegetables, nuts and seeds.
There is a case history on Natural News that did just that and reversed his diabetes within 30 days.
Shelton advised anyone who had been insulin-dependent for some time not to fast or in his own words "highly inadvisable" so a lot depends on the length of time you have been on insulin.
