There may soon be less of Michael Moore. The portly propagandist is doing a stint at the Pritikin Longevity Center & Spa in Aventura, Fla. — also known as the "fat farm for the rich." Moore is learning how to cook healthy meals and exercise and attending classes on "life re-education." The program starts at $3,800 a week and promises enrolees they'll "learn a new approach to eating," "never have to diet again," and can lose up to 12 pounds in the first three weeks.
