Jim's weight used to affect his nine-year marriage to Dana, a Pilates instructor. "When I met him he was 240 and I thought he was big then," she recalls. "When we got married he was 320 and he promised on the honeymoon that he would start to lose weight."

Using food as a comfort mechanism caused Jim to create unhealthy eating patterns. His fun-loving radio persona was known for being overweight and his staff and audience often egged him on to eat more.
