Cameron Diaz Battled Acne, Binged On Greasy Food Back In The Day

Cameron Diaz is pretty much Hollywood's poster child for a healthy lifestyle, but apparently she didn't always eat right and work out daily.

The 41-year-old actually ate so much greasy food as a young woman that she ended up breaking out and suffered from painful acne. Diaz opens up about her struggle and cutting out the junk in Seventeen magazine's February issue, admitting, "I was this skinny girl who could eat anything I wanted without gaining an ounce -- so I did. If you really are what you eat, I would have been a bean burrito with extra cheese, extra sauce, no onions!"

Read an excerpt from her piece in Seventeen below:

You might think my life is always totally glam, but I used to have horrible acne -- deep, boiling pimple -- the kind that hurts so badly, I didn’t want to leave my house. My friends said they didn’t notice, but I’d say, “It’s the only thing anyone can see!” No amount of concealer and foundation could take away the texture of my skin, the embarrassment I felt, or the pain of those raging pimples. I was miserable.

At the same time, I was this skinny girl who could eat anything I wanted without gaining an ounce—so I did. If you really are what you eat, I would have been a bean burrito with extra cheese, extra sauce, no onions! Sometimes on a Friday-night drive-through run, I would order a double cheeseburger with french fries and onion rings. I was the poster child for being both skinny and unhealthy—and I had the zits to prove it.

I thought I’d tried everything to make my skin clear up, but I didn’t realize all that fried, greasy, processed artificial crap was setting off a hormonal surge that sent my skin into crazy town! Once I cut out the junk, I saw such a major difference that I felt like an idiot. It not only cleared up my acne, but it also gave me this huge amount of energy. I realized our bodies are these amazing machines, created to be good to us when we’re good to them. I could hear my body when it craved more veggies or water. I had energy to spare, which was something I’d never felt before. I couldn’t believe I had been drowning out my natural cues for so long! I started reaching for avocados and tomatoes because they made me feel great. I went from focusing on how my face looked to focusing on all the awesome things my body is capable of.
