Susan Powter is an Australian-born motivational speaker, nutritionist, personal trainer and author, who rose to fame in the 1990s with her catchphrase "Stop the Insanity!", which was the centerpiece of her weight loss infomercial. Photos of an overweight female served as a backdrop to her stage presentation, and while they appeared to represent Powter in earlier years, they were generally considered somewhat unrecognizable as Powter, leading to accusations of fraud. She hosted her own talk show The Susan Powter Show in the 1990s. 

December 22nd, 1957 in Sydney (Age 66)
