Yes, WW Core is very similar to South Beach. I've got a sister and a good friend both doing Core, and they are both having success and love the plan. They like variety, so I think Atkins limitations wouldn't work for either of them. I'm just glad they both found something that works.

Check out the South Beach threads here, too, since Core is so similar to South Beach. Judynyc, IIRC, is on the Beach and she has not only reached her goals, but she's an incredible inspiration around here.
