After her failed sitcom Fat Actress and now on her Lifetime reality show Kirstie Alley's Big Life, it was no doubt that Hollywood and much of America didn't have a whole lot of faith in Kirstie ever finding weight loss success. Critics may have to eat their words soon.

She's joining a recent trend of Hollywood's larger than life actors working hard and dropping weight. Drew Carey was in the news recently after a huge 80lb weight loss. Alley Tweeted on Thursday, "I've lost over 50 lbs...and I'm having the time of my of my life...30 more to goooooo" She had signed up with Jenny Craig a few years back and had lost 75 lbs. She announced her weight loss on The Oprah Winfrey Show but then gained it all back last year.

Yo-yo dieting is terrible for your health, and self esteem. We hope that this time, Kirstie can stick with it and keep the weight off.
