A liquid only diet will mess with your stools. (Not sure about the urine... too much beta-carotene? dunno). I've been on a couple of liquid diets. The Fortisip one, where I allowed myself soups, smoothies, etc. as well, wasn't too bad, but the Elemental 028 one was horrific. The latter is an elemental drink where basically all the nutrients have been 'predigested' (broken down) into their simplest parts, e.g. proteins into amino acids.
It literally tasted and smelled like artificially-sweetened vomit. I lasted 2 weeks. If I'd stayed on it the full 6 weeks, I reckon all my hair would've fallen out and I'd have been sectioned, I was that mental on it.
Liquid diets have a good track record for children with small bowel Crohn's disease, but don't seem to be as effective for adults or for disease in the colon.
