I know a few people who have tied it and they swear by it and say they would never go back to their old eating habits. That being said they say it takes a few months of commitment before it really takes effect AND you cant shortcut at all and need to remain very strict when following this type of diet. A few of them have SLOWLY experimented with adding other stuff in the mix like broccoli or whatever but the results of these additions vary from person to person so you need to find what works for you specifically in these cases.
