Hi, and welcome!
I don't know much about the South Beach Diet (I assume that's SBD). But hopefully it turns out to be a good choice for you in the long run.
I think it has its own section of the forum here so you can likely find some great support there, regarding phases and stuff.
Mind you, you should participate wherever you like.
This is a great place for general support, whether it be emotional, or figuring out what to eat, and so on.
Keep up the great work and hope to see you around the forums!
