I followed that diet for 2 weeks.....made me worse too. I think if your UC is caused by an infection of some sort, that diet will help. It will starve the bad bacteria out, but if your UC is caused by something else, it won't help. It is always a good idea to reduce sugar, but your health is more important. If you feel really crummy, can you add back a tiny bit of what you used to eat and see if it makes a difference? Or you could wait it out and hope for the best. I always wondered if I would have implemented the diet by weaning out sugar instead of going cold turkey, if that would have made a difference. Anyway, good luck and keep me posted, I will be thinking about
you and hoping you feel better soon.
