Ok I have another question. I had mentioned to the doctor (because he had told me to try this--bad idea) that I had been doing slim fast, staying at 1400 calories everyday and taken Xenadrine EFX. After two and a half weeks of this was when my symptoms came back. He told me not to do it anymore and because he's not well versed on IBS that I should do some research on how I might be able to lose weight without discomfort. Has anyone lost weight by dieting with IBS and if so, how so?Thanks!
