Kirstie Alley made headlines earlier this month when she hit the runway at Malaysian designer Zang Toi's Spring 2012 fashion show during New York City's Fashion Week looking sleek and slimmed down.
In fact, the actress and former "Dancing With The Stars" contestant has lost 100 pounds and has dropped down to a size six.
"When I hit that mark, I went, 'That's it!'" Alley told People magazine in a recent interview. "I have more energy than I've ever had in my whole life."
The 60-year-old tells the magazine she hovered around 230 pounds at her heaviest and said, "My body had gotten really week."
"There was nothing positive about being fat," she added. In the photo above Alley is seen at the premiere for the film "The Runaways" on March 17, 2010 on the left. The center photo is a promotional image from the beginning of the 12th season of "Dancing With The Stars" in March 2011.

The actress competed on the ABC ballroom dancing series "Dancing With The Stars." She and partner Maksim Chmerkovskiy placed second. Alley also shed several pounds during her time on the show.
Talk show host Ricki Lake, who is one of the contestants of the upcoming 13th season of "Dancing With The Stars," says she agreed to compete on the show after watching actress Alley overcome hurdles on the previous season.
Alley rose to fame with the 1980s sitcom "Cheers" and played a former model on the comedy series "Veronica's Closet" in the late 1990s.
The actress has battled weight problems throughout her life and has in recent years poked fun at the issue on her own television shows, such as "Fat Actress" and "Kirstie Alley's Big Life," and on "The Late Show with David Letterman" in July.
Alley said that her stint on "Dancing With The Stars" and following her Organic Liaison diet, a weight-loss program which Alley started, helped her drop a few sizes.
The actress and frequent Twitter user said that she feels "back to normal" and is "looking to be madly, deeply in love."
"For the first time in my life, I know exactly what I want in a man," she told the magazine. "I want someone who has my back, who is courageous and brave."
