Awhile ago, I was watching Penn & Teller's Bullshit on Showtime. The episode was about detoxing your body through diets or colon cleanse things and whatnot. Obviously, Penn & Teller thought it was a bunch of crap. Personally, I'm a bit more middle of the road. I have some friends that do the diet detox every once in awhile and they seem to get some sort of help from it. I don't think I would ever do it myself though. Mostly because I'm not dedicated enough to keep up with it long enough.
