The 2003 book that made a posh Miami neighborhood part of everyday weight loss speak, The South Beach Diet, is getting updated. The book, which spawned a cottage industry and four cookbook spinoffs (as well as a “good fats/good carbs” title and a healthy heart one), is getting a face-lift from author and doctor Arthur Agatston. The book, The South Beach Diet Supercharged, is scheduled for an April 2008 release from Agatston’s longtime publisher Rodale.

Dubbed the “next generation” of the brand by v-p and publisher of Rodale, Liz Perl, the new book, subtitled FasterWeight Loss and Better Health for Life, incorporates an exercise regime that, coupled with the food program, promises to speed up metabolism. Agatston, who collaborated with physiologist Joseph Signorile, Ph.D., on the book, said the fitness program will “significantly enhance the lifelong health benefits of living the South Beach lifestyle.”

According to Rodale, there are over 22 million copies of its seven South Beach books in print.
