Well, here's one way to maintain a thin Hollywood physique.
Says Megan Fox, 24, in the June issue of Allure (on stands May 25), "I'll starve to death before I'll cook for myself. I think I could survive a week without eating.
She has mixed feelings about plastic surgery, though.

"I would encourage anyone to first speak with a therapist, to try and figure out where this want comes from, because a lot of times it's not related to your teeth or your nose or your chin -- the surgery is not going to alleviate that insecurity for you," she says. "If, then, you feel, 'This is something that I want to do', then do it. It's amazing that we have the technology to do the stuff that we do."
Fox -- who is on-again with beau Brian Austin Green -- says she prefers to spend time with herself.

"I could go days, weeks, without talking to another human being," she swears. "I hate receiving compliments; I hate being told I'm talented or people think I'm going to be a movie star. I always feel that it's forced and fake."
She says she'd like to cause "physical harm" to the photographer who snapped topless photos of her while she was filming Passion Play.
"I'm not a f--ing reality-TV star that's courting the paparazzi and wants my f—ing picture taken all the time. I'm at my job and I'm trying to play a character and I'm trying to be serious, and this is the sh-- that's happening to me. It makes me furious," says the actress, who dropped the F-bomb 24 times during the interview.

Fox admits she has obsessive compulsive disorder. "This is a sickness, I have an illness -- this is not OK anymore," she says.

She refuses to use public toilets without covers or eat with restaurant silverware.
"Every time someone uses a bathroom and they flush, all the bacteria is shot into the air," she says. "Putting my mouth where a million other mouths have been, just knowing all the bacteria that you carry in your mouth? Ucch!"
