Susan Powter (born 22 December 1957) is an Australian-born motivational speaker, nutritionist, personal trainer and author, who rose to fame in the 1990s with her catchphrase "Stop the Insanity!" She hosted her own talk show The Susan Powter Show in the 1990s.
Powter was born in Sydney, Australia in 1957, living there until she moved to the United States at age 10. She left school in 9th grade. Twice married, she described herself to Curve magazine in 2004 as a "radical feminist lesbian woman". She has two sons from her first marriage, Damien and Kiel. She adopted a third son after her second marriage.
In 1994, Powter starred in her own talk-show style television program called The Susan Powter Show, which ran for one season. On the show she and guests discussed nutrition and fitness as well as other topics.
Motivational speaker and nutritionist
Advocate of a whole-foods, organic, low-fat diet, and regular cardiovascular and strength-training exercise, Powter set herself apart from other nutritionists by condemning the diet industry as a whole. Her platinum-white flat-top haircut,aggressive manner of speaking and being barefoot while speaking in public, became an iconic element of her celebrity. She has since grown out her hair and has multiple tattoos.
Powter was originally based in Dallas, Texas at the height of her fame. She eventually sold her studio in Dallas and moved to Seattle, Washington.
Author and blogger
Powter is author of several books, three of which became New York Times best-sellers in the 1990s. In 2002, she returned to writing with The Politics of Stupid, a stream-of-consciousness, self-published manifesto encouraging women to take control of their brains and bodies from food manufacturers, corrupt governments, and fitness/diet industries.
Powter's website reported that she would host a radio show beginning in May 2006 and a cooking show entitled Taste My Broth within the year. She also puts out The Monthly Flow, a subscription-based multi-media e-zine.
In November 2007, Powter re-launched her fitness and wellness blog.
