Kara DioGuardi opened up to Women’s Health Magazine for their upcoming April issue. In it, the 'American Idol' judge discussed her battle with an eating disorder, her healthy eating habits, exercise routine and personal growth.

She battled an eating disorder in her early twenties: “I’d pretty much clean out the refrigerator. Food was my drug of choice. It anesthetized me so I wouldn’t have to feel whatever I was feeling. I’d stuff myself full of sugar and fall asleep.�

Healthy eating habits: “The more roughage you eat, the more it fills you up.�

She drinks lots of water: “Two huge bottles a day, minimum. I have them around – one upstairs, one in the car – to force me to remember.

Her exercise routine: “Two miles of running or 25 minutes of cardio – boxing, treadmill, step-ups, walking lunges, sprints. I mix it up. And weight training is important as you get older. You build muscle which burns fat when you’re at rest.�

Her loved ones are honest with her: “Someone [close to me] said, ‘You may want to work on your arms – they’re a little jiggly’…The people in my life have no qualms about telling me when I don’t look great.�

After getting her first job in the music industry: “I started to feel better about my life. I was answering phones and getting water but I also learned about the music business.�

On her plans to take some stuff off her plate when she has kids…“It’ll be a lot of pressure being in charge of a little soul who will someday judge me if I’m not there for the school play.�

She’s finally content…“For the first time in my life, I’m content. I don’t feel the need to prove myself anymore.�
