'Hungry' Author Dr. Robin Smith To Oprah: I Was 'Emotionally Anorexic' (VIDEO)

A few years ago, Dr. Robin Smith was on top of the world. The bestselling author had a full schedule of speaking engagements, a life filled with family and friends and a job hosting a show on Oprah’s XM satellite radio channel. But in her new book Hungry: The Truth About Being Full, Dr. Robin reveals that she was still starving for true fulfillment.

In this advance clip from the March 10 episode of “Super Soul Sunday,” Dr. Robin says that she was “emotionally anorexic” despite her outward successes. “What it means is someone... and a lot of people are like this, who are calling themselves 'full' off of crumbs. You can't get full off of the crumbs of life."

“But this is what I didn’t understand,” Oprah says. “You are Dr. Robin.... You've helped other people figure it out for themselves.”

"I was hungry," says Dr. Robin. Then she explains that "emotional anorexia" can happen whenever people know they're not being fed emotionally, but still tell themselves the lie that it’s okay.

“Super Soul Sunday” airs on Sundays at 11 a.m. ET on OWN.
