Eliminating food for a period of time is a common approach in Scandanavia when treating refractive UC. I think you will see that for some it helps and others it doesn't. My GI tried this approach on me in the hospital, fluids and no food for 9 days. The bowel rest helped me physically but overall did not gain me remission. I know others who have gone as far as TPN and seen no results. However, for some this approach does work. There seems to be no one approach to treating UC that helps all but that doesn't mean you shouldn't try. As for David Klein, I think he's like everyone else out there trying to sell a cure. I'm not sure I even believe he was ever diagnosed with UC and there is no way we will ever know that. Again, if you believe what he's pitching, go for it. I tried everything to save my colon, and I tried a lot of weird things, but I never found the magic cure.
