Kirstie Alley
She earned a star on the Hollywood Walk of Fame and has had hit films and TV shows. She's also had yo-yo dieting dramas, as any fan of "Fat Actress" or "Dancing with the Stars" (or grocery store tabloid) knows well. Kirstie Alley, 63, had a gig as a Jenny Craig spokesperson for a few years, but by 2008 she'd regained most (if not more) of the lost weight. She has since embarked on a serious weight loss effort and has dropped 100 pounds through hard work, diet and exercise, she claimed: "Thank u for all your SWEET comments," she tweeted. "NO surgery, NO flippin lasers, NO barfing, NO starving... [Just] my products, organic food, dance."
