Jennifer Aniston Reveals How 'Cake' Was 'Trying on My Body'

— -- Jennifer Aniston has already talked about letting herself go for her acclaimed role in "Cake" -- now the actress is revealing she actually suffered a few injuries while filming.

"Physically, this movie was trying on my body," she told Deadline in an interview published yesterday. "I had a lot of pinched nerves just from being in that physical space for five weeks straight, but I missed it when it was over. We had so much fun together. We were like a little theater group."

This revelation comes after the former "Friends" star, 45, went on the "Dr. Oz Show" earlier in the month and revealed her Oscar-worthy performance affected her body and her mind.

In "Cake," she plays a character Claire Simmons, who deals with chronic pain. The actress had to stop working out for a while to make the part convincing to the audience.

This lack of exercise really affected her in the real world.

"It really was interesting when you stop working out how you just ... my serotonin levels went down. My stamina was shot. I was cranky. I was irritable," she said on the show. "I found myself short. I was hungry like crazy."

Talking further with Deadline, Aniston said she thinks this role will really help her break a stereotype she obtained after being on a hit show for a decade.

"From being on a television show for 10 years—that’s in your living room week after week, and now day after day (in syndication). You really do have to kind of run far, far away. But it’s OK. I don’t mind that. I’m up for that challenge, and that’s what excites me ... I would be lying if I said in taking this on, there wasn’t a part of me that knew I was taking a risk. I knew I had to do it for myself and if it was going to fail and fall flat on its face, then so be it, but I had to."
