During the final seasons of "Growing Pains," instead of growing up, Carol Seaver visibly shrank. The 19-year-old star was dangerously underweight, reaching 80 pounds at her rock bottom. Anorexia hospitalized Tracey in 1992, and the young actress spent her early 20s fighting -- and recovering from -- the disease, all while in the public eye. Today Tracey's been married for nearly 20 years and is a mother of four, but her adulthood hasn't been drama-free. In 2004, she was arrested for driving under the influence after crashing her SUV while driving her husband and three kids. In 2011, Tracey put anorexia in the spotlight again as the host of "Starving Secrets," a reality show chronicling 10 women with eating disorders as they progress through eight months of treatment.
