Is there anyone out there doing the Ian Smith Shred diet? Or have you done one in the past?

I have just started the Revolutionary Shred Diet by Ian Smith. In the first four days I have lost 4 pounds. I am looking for someone that has been through this program, or better yet if you are just starting it or thinking about starting it. Or maybe there is a group I can join on MFP, but I have not found one. TIA
