The folks at Ballantine are crowing about the success of Sugar Busters!: Cut Sugar to Cut Fat, which moves into the #1 spot after two months on the national charts. The latest energy surge is due to Dateline's eight-minute segment on June 16, featuring the book and its authors -- H. Leighton Steward, Dr. Morrison Bethea, Dr. Luis Balart and Dr. Sam Andrews. The four, all New Orleans residents, originally self-published the book to much local success. The Dateline appearance, which followed their 13-city national tour, was the icing on the cake for the book's success. Ballantine reports 465,000 copies in print after 10 printings (first printing was 125,000).
