Cameron Diaz dishes her top weight-loss, diet and workout secrets in her new fitness book, The Body Book.
"Love your own amazing body," Diaz told USA Today Jan. 6. "Know your body. The only way you can know that body is by taking care of it properly.
"If you are eating processed foods, and you're not getting all your nutrients, not exercising properly, then you are not living in the body that you were meant to live in."
The lithe 5-foot-9 Cameron is hailed for her super-toned physique, but said she wasn't always so fitness-minded, and used to eat fried junk food every day. Her poor diet led to acne and other skin problems, and made her exhausted and depressed.
"I didn't think I needed to change the way I ate because everyone told me, 'You are so skinny. You can eat whatever you want,'" she recalled. "But I felt sick in my own body."
Cameron said she didn't start exercising regularly until her late twenties, when she trained for the film "Charlie's Angels."
I watched my body transform over a week of intense training — some days doing upward of 1,500 to 2,000 kicks a day. Kicking, kicking, kicking for eight hours.
All of a sudden I had six-pack abs. It was painful. I would not recommend that anyone blast their body like that. It was an intense, physical challenge, but it woke me up to my own body and what it was capable of."
Cameron now makes working out a daily habit, combining cardio exercise like running on the treadmill or the elliptical trainer, with light weight-lifting.
Diaz follows a low-carb diet featuring whole foods like green vegetables and lean proteins. She cooks for herself every day, usually eating a breakfast of steel-cut oats, egg whites, sauteed greens (collard greens, kale, zucchini) and caramelized shallots.
Diaz looks fantastic, but said she also feels amazing because of her healthy diet and workout regimen. The main message Cameron hopes to impart in The Body Book is to love your body, no matter what your weight or size.
"[Women need to] stop hating their bodies, understand them, take care of their bodies and put that energy that they would be turning on themselves in a negative way out to the world in a positive way," she said.
Cameron said the best way to show love to yourself is to take care of your health. "I don't look at exercise as a chore," she said. "I look at it as something I get to do.
"I am grateful that I can move my body in that way. I want to make sure I don't get sick. If I'm blessed to get older, I want to make sure I can maintain quality of life."
