Kirstie Alley

Kirstie Alley was at her largest at 219 lbs., she admitted on The Oprah Winfrey Show Monday, and to date she's shed 55 lbs. of that, and has her sights set on dropping another 25-30.

"I made some good decisions simultaneously with some bad decisions," Alley, 54, said of the way she let her body balloon. "The good part of it was, 'I'm going to spend more time with my kids (William, 13, and Lillie, 11), I'm going to cook.'

"The bad decision was – and this is the dumbest decision I've ever made in my life – it went like this: If a man really loves me, he will not have to love me for my body. He will really love me just for me. … When did I decide I was a big, fat girl?"
