Jean Nidetch, the founder of Weight Watchers International, was once a housewife who weighed more than 200 pounds. She slimmed down to 142 pounds in 1962 and has never been heavy again.
Now, at 86, she lives in a retirement community in Parkland, Fla., and has written her autobiography, The Jean Nidetch Story.
She says she never dreamed that her weight-loss experience would lead to a successful international company that would help millions trim down.
