Portia de Rossi on 'Oprah': Surviving 82 pounds at her lowest and a 300-calorie diet

Actress Portia de Rossi, who recently took her wife Ellen DeGeneres' last name legally, appeared on "The Oprah Winfrey Show" Monday (Nov. 1) to talk about the revelations she experienced writing her new memoir, "Unbearable Lightness." The actress describes her struggle with eating disorders - both anorexia and bulimia - which started at age 12 when she began modeling. 

"It was very cathartic for me to write," de Rossi says. "It was difficult for me to write definitely. There were a lot of tears shed on that keyboard."
The former "Ally McBeal" star's weight dipped to 82 pounds at its lowest. And she tells of restricting her daily diet to yogurt, laxatives and 300 calories, sometimes cutting that in half to 150 calories.
