(WHAS11) -- Jennifer and Kimberly Zehnder both share the same disorder.
“Learning every fat gram, every calorie of every fast food restaurant and in the grocery store,” said Jennifer.
She became anorexic in the 7th grade and her disorder evolved into bulimia.
“I would have buckets behind the toilet. I would go into the shower with a bucket and throw up hoping no one would hear me,” said Jennifer.
Her daughter Kimberly, a sophomore at Manual High School, suffers from her own eating disorder. She had a poor self image that she said developed from learned behaviors.
"We weren’t allowed to have anything but water when we went out to restaurants, no cream sauces, no sodas in the house and it just really took a toll on me,” said Kimberly.
“It’s heartbreaking because it’s a disease you'll have for the rest of your life,” said Jennifer.
The two will appear on the Katie show, an experience they call positive. Both said food and eating is still a daily struggle, but therapy has helped them both.
“It separated us for a while, but now since we both brought stuff up to the surface I think it's helped us both heal,” said Kimberly.
Their episode on “Katie” airs Monday at 3 p.m. on WHAS11.
