"I'm going to adopt," the 36-year-old tells Women's Health magazine. "I can’t handle doing that to my body."
"Also, when you rescue something, it's like rescuing a part of yourself," she adds.
Jillian was overweight as a child and after winning the battle with obesity she doesn't want to risk undoing all that hard work by gaining weight with a pregnancy.
Her attitude has attracted widespread criticism from the health industry, with some experts accusing her of passing on dangerous ideas to other women about the 'health risks' of pregnancy.
Meanwhile, others have praised her for wanting to save a child in need no matter what her reasons.
