You Won't Believe What These Celebrities Did To Lose Weight

As if money and fame weren't enough, most of Hollywood's hottest stars have great figures, too. As much as they would like us to believe that it's all in the genes, sometimes they actually have to work hard at looking that good. Most have personal trainers on retainer; some hire a private chef. Despite having these tools at their fingertips, the lure of the quick-fix fad diet is too appealing to pass up, even for celebrities. See, they're just like us!

Christian Bale famously lost 63 pounds for his role in The Machinist by eating just an apple and a single can of tuna fish a day — one of Hollywood's most talked-about weight-loss stories. Notorious up-and-down dieter Kirstie Alley once dropped 75 pounds on the Jenny Craig regime.  Whether slimming down for a role or just dropping the avoirdupois to look and feel better (and maybe get a role), the men and women who entertain us have gone to some wacky extremes.

From an A-list sitcom stars that eats like a newborn to herself with baby food to a superstar singer who stays drunk all day, here are some crazy celebrity diets.

Jennifer Aniston

Trainer to the stars Tracy Anderson created the crazy weight-loss plan known as the Baby Food Diet, which she calls a "cleanse." Several of her clients tried it, but it was when Jennifer Aniston jumped on the bandwagon that Gerber got excited.  She lost 7 pounds in one week, something Anderson said was possible because the diet gave her body a "boost."

Beyoncé

These days, Yolanda Foster is the Master Cleanse's biggest fan. But before the Housewives fan jumped on the lemon juice bandwagon, Beyonce sucked it down.  She needed a plan that was fast  — like 20 pounds in two weeks fast — for her dream role in Dreamgirls. "Normally they'd just change your makeup or your clothes but I wanted to go the extra mile," Beyonce told China Daily. "Back in the sixties, models like Twiggy were popular and I knew Deena would have been thin then, so even though I love eating, it was necessary to lose weight really fast because we shot Deena at 36 and then Deena at 16 two weeks later."
