Kirstie Alley – 120 lbs

Kirstie Alley is one of those celebrities who have had her fair share of ups and downs when it comes to weight loss, which is why many of her followers can relate to her. Over a dozen years ago, the Cheers star lost about 75 pounds by following Jenny Craig’s program.

Alley’s weight went off the charts again in the subsequent years, but this time, she dropped 100 pounds. The physical exercise she got throughout her time in Dancing with the Stars helped on top of adhering to an organic diet. Alley’s most recent appearance was as Suzanne in You Can’t Take My Daughter.
