Possibly a silly question, but are South Beach and Sonoma really any different from Atkins? I admit I used to be one of the people who thought that Atkins was the "No Carb" diet. But since finding out that it's not the case and reading up on his actual diet, I'm sort of scratching my head in regards to the other two. Now it seems like Sonoma is just Atkins with a wine list? Is there really a difference, or did Agatson and Gutterson just try to figure out a way name things differently enough to avoid trademark infringement?
