So long, South Beach Diet!!!

I've been on the South Beach Diet for over a month now, and it's going very well. I haven't had a piece of bread (except for 2 hamburger rolls...which was an emergency...yeah, that's it) during that time. I'm trying to lose weight, eat healthy, blah blah blah, and now I read this. Being 15-25 pounds overweight can be healthy, doctors say?? I'm turning down cake and cookies, not eating carbs, wolfing down vegetables like they're going out of style, and now this? Where were you indecisive bastards 30 days ago when I started this thing??
