I agree with the way RNMOM does this. I know last time I did SBD my cravings went during P1 - I still blew it but thats another story!
This time, my cravings are gone. I get a brief thought come into my head about chocolate or bread or alcohol, but then it goes. Whereas I've spent more than half my life battling DAILY cravings and sugar/carb binges.
I will move to P2 at the end of my 2 weeks - but will certainly use P1 again whenever I feel the cravings coming back, if I slip badly off the programme, or after, say a vacation.
P1 facilitates P2 by shifting those cravings. If I just went straight to P2 it wouldnt work for me because I would still be having cravings and bingeing (sp). I've tried it and it didnt work for me.
Its taken me, as I said, more than half my life, having been dieting since I was 17 to find something that causes me a)to stop bingeing and b) allows me to lose weight.
Its different for everyone. I've been reading an excellent book called "Thin For Life" and it really shows that each of us has to discover for what works for us as individuals and then take it from there.
Ok I just went to get my copy of the book here I quote verbatim from P12 of the most recent British edition :
"
One beauty of the three-phase structure of the South Beach Diet is that you can move easily from one stage to another. If, while in Phase 2, you go on vacation and overindulge in sweets, its easy to switch back to Phase 1 for a week, lose the weight those desserts
put on and then return to where you left off in Phase 2."
So the book is contradicting the official website? Perhaps the question is ambiguous. I agree that if a person is strictly OP during Phase 2, then moving back to P1 probably is not a good idea. But if a person has slipped and had a relapse, moving back to P1 makes sense to me.
