Ricki Lake
Ricki Lake was only 19 when she was cast as Tracy Turnblad in Hairspray. It was also when she was at her heaviest, at least 200 pounds. However, when the opportunities stopped knocking on her doors, it hit her; that it was the time to lose weight. She successfully did, even after she gave birth to her child.
Lake also famously shed pounds after joining Dancing with The Stars and admitted that the exhaustive training helped her trim her problematic areas. At 52, the Cry-Baby star was last seen performing in The Masked Singer in 2019.
