Kirstie Alley has lost 100 pounds since her peak weight. That's amazing.
But how does the Dancing With the Stars finalist plan on keeping it off?
On New Year’s Day, Alley launched 100 Days of Dance, a program in which she encourages people to dance for 100 consecutive days in order to lose weight or stay fit.
"I want everyone to experience some version of Dancing with the Stars," says Alley, 60. "People don't have to do monotonous, zombie workouts that are boring."
"Dancing is free and you can do it anywhere and any time."
The actress, now a size 6 and 130 lbs., says she backs up her big talk, staying fit by dancing 1-2 hours a day and following the diet plan Organic Liason.
She'll post videos of herself dancing on the site for 100 days starting on Sunday and she hopes to spotlight exotic locales with special guests along the way.
