Hello,
It's good to have you here asking about the SB approach to nutrition and health. Of course, everyone here will tell you
good things about the South Beach way of eating - LOL - because we practice what we preach!!
Phase 1 (two weeks) is restrictive to help get people out of the sugar addictions that so many seem to have, AND, to provide a jump start to the weight loss. Most people see good results right away and are more inclined to continue.
Have you read the book? It is really informative (Dr. A is a cardiologist) and very helpful to have around. In the meantime, read the stickies in the SoBe FAQ section (here) and scroll through the archives to see which questions interest you. (Hint: look at how many replies and views a thread has)
Here is one link to get you started:

As with all other reasonable approaches to weight loss, dedication and determination are essential. The South Beach way is simple and straightforward, and it works!
PS - the board is a little slow right now with the holidays, but you will always have someone offer support, guidance, info or a helpful referral, (sometimes the responses are quicker than others.)
