Susan Powter has experienced a lot of change in her life after she rose to fame with her fitness infomercials. After her first husband, Nic Villarreal, left her for another woman in 1986, Powter went from 130 pounds to 260 pounds - and turned to fitness to get her through. In the early '90s, Powter rose to prominence with her "Stop the Insanity!" fitness infomercials and went on to create a massive wellness empire, authoring several books and creating her own talk show, The Susan Powter Show.
