I did buy the system and I havent started the 21MM yet because I decided to do the 6 day detox first. The 3 weeks on the 21MM has you take baby steps but you do eat regular foods. Example day one teaches you to snack in between, and you have great lists for everything you can eat on. I personally do better with lots of tools in a program and this one does I have learned a lot just reading through the info I got in my kit. I think what the other members are saying though you just need to find what works best for you.
