It's too restrictive to work for me, so no, I've never tried it. An online friend of mine did and claimed it changes the workings of your gut so if you ever want to go back to a regular diet, you need medical help doing so. Otherwise it could make you very sick. So, I'm not sure how well it works for people. I've seen ads online claiming it can cure almost everything, but I'm skeptical of diets claiming to do that. Who is sponsoring them?
