Kirstie Alley’s weight has fluctuated throughout the years and the Jenny Craig spokesperson is now revealing yet another shocking weight loss photo.

Alley lost 50 pounds with the help of the diet program. When she was a spokeswoman for Jenny Craig for three years starting in 2004, she shed a whopping 75 pounds.

"It was so easy for me when I did it before," she told People.

The 63-year-old actress added, “There's this certain place I hit where I felt really energetic and agile. I was like, I want to keep going with this!"

Her goal was to lose 30 pounds, but she lost 20 more pounds than she had set out to lose.

Alley is also vowing to keep the weight off this time, saying "I want it to be part of my life this time. I'm just trying to make it fun."

She said she was inspired to lose weight after watching herself on her sitcom Kirstie.

“I was like, you look OK on the street, but you don't look [OK] on TV, not so much,” she said on the Today Show in April.
