Meryl Streep and Amy Adams Ate Their Way Through 'Julie and Julia'

Usually, actresses are encouraged to watch their figures while filming a movie. However, that was far from being the case on the set of "Julie & Julia." The film shows the way food impacted the lives of two extraordinary women, Julia Child, who wrote "Mastering The Art of French Cooking," and Julie Powell, a writer who made every recipe in Child's book and blogged about it.

Nora Ephron, director/writer/producer of the film, insisted her cast not only eat the food prepared on set, but enjoy it. And enjoy it they did. In an interview with Ladies Home Journal, Streep admitted, "I gained 15 pounds. I'm still trying to lose it. It was worth it."

Adams' weight gain wasn't as drastic, but she said to Access Hollywood, "Eating, eating, eating and eating. As long as the costumes fit, I could eat as much as I wanted, which was great. There was some weight gain but I didn't weigh myself so I really don't know."

Streep is no stranger to fluctuating weight. To get slim and trim for her role in "The Devil Wears Prada" after going for a more rotund look in "Prime," Streep counted on swimming and watching her diet. She told PEOPLE, "I have been pushing the wine bottle away -- at least after the first glass. I have to fit into these clothes."

So, will Streep go back to what worked before, and maybe share her secrets with her co-star? Or do you think she'll shed the weight in a new way this time around? Either way, we're sure both of these stars will be back in superb shape in no time!
