The New York Times article: New Doctor, New Diet, but Still No Cookies covers a topic that remains compelling and controversial. It's a great overview of the South Beach Diet and the book that promotes it.
Bottom line: South Beach seems to be more reasonable than Atkins .. and it may very well fit the bill as an ideal plan for those interested in avoiding diabetes and/or reducing their risk of cardiovascular disease. I'll read the book .. um .. when I have free time .. after the kids finish college.
