I've tried it, I still have the kit from like...a year and a bit ago.
What to say about it:
- I was the body type that was pretty much low fat, low carb. (If you want I can give you a food list of what you can eat if you do the 6WBM "body type test" to see if its worth the money).
-In addition to eating well, you are told to do 30 minutes of walking (I believe) or like wise activity along with the band work.
- Personally, I found it difficult because I lived at home, but now that I don't I could almost see myself doing it again, but I've taken on a no-meat type lifestyle so it doesn't really work
