"[Hibbard] represents a group of individuals who develop eating disorders during a competition to lose weight because psychologically they are getting so much praise and admiration from other people that they'll do anything to sustain their weight," said Kushner.
"If they put it back on there would be embarrassment and a sense of failure," he said.
Hibbard says she overcame the pressure to keep off the weight only after her family staged an intervention.
"My family was worried I was going to drop dead," she said. "They babysat me for weeks on end as I went through therapy and met with a nutritionist."
Hibbard said she struggled with the eating disorder even while she was pregnant, forcing herself to go on runs even as she bled.
"I remember my very first meal when they tried to have me eat a substantial amount of food -- and it was only an egg white omelet and some blueberries -- and it took me and hour and a half to eat and I cried through the entire thing," she said.
Today, Hibbard is married with a healthy 20-month old son, but said she still has her demons when it comes to food and weight loss.
She allows herself to indulge and limits her workouts to three to five times a week, but hopes that by speaking out she'll educate others about how hard weight loss can be.
"If I'm going to accept praise and gratitude for being part of something that really inspires people, I also have to accept responsibility for people who struggle," she said. "People come to me and say they can't lose weight as fast as they saw me do it [on the show] and that they've become bulimic or anorexic."
"I want people to know that I'm incredibly sorry if I did a disservice by deceiving them by the amount of weight I lost on TV and that I'm on the same long journey that they're on."
