WHAT MAKES HIM HAUTE: This Palm Beach resident saved American waistlines with the founding of Slim-Fast in 1976, which has grown into one of the most successful diet lines available. He uses the windfall from that success to help others. He is very active in a number of causes and advocates for improving health care and nutrition. He also has strong ties to Israel, which led him to found the Center for Middle East Peace & Economic Cooperation, in 1989, and he still serves as the chairman of the nonprofit. His book, Peace is Possible, offers an unprecedented account of behind-the-scenes discussions with Middle Eastern leaders.
