Cameron Diaz feels unstoppable at 42, saying she would rather be this age than be in her twenties again. Diaz made the remarks at the Los Angeles premiere of her new film, "The Other Woman," which co-stars supermodel Kate Upton.
"I love being in my forties," Diaz told E! "You know yourself and you don't give a s--t anymore. You really don't care what other people think. You let go of that things that don't matter. It's a liberation. It's fantastic."
Cameron, a former model who has been celebrated for her athletic beauty for the past two decades, said being young has its advantages, but getting older has given her confidence and perspective.
"Who wants to be 21 again?" she laughed. "It was horrible! They were not the best years of my life. The best years of my life are right now."
Diaz, who has a super-fit body a woman of any age would envy, said a healthy diet, daily workouts and a positive attitude are responsible for her trademark enthusiasm. Cameron has starred in numerous blockbuster films, but said writing her fitness book, The Body Book, is one of her proudest achievements.
'Take Care of Your Body and Your Body Will Take Care of You'
Diaz said she penned the book to encourage and inspire other women to celebrate their bodies and take control of their health. While diet and exercise help you look good, Diaz said it has an even greater impact on your emotional and psychological health.
"We concentrate too much on what's happening on the outside," she said. "If you take care of what's going on in the inside, then you should have no problems."
Diaz said overhauling her diet made a huge difference in her skin and her energy level. "I used to eat fried food from morning to night when I was in my 20s," she told USA Today.
"As I get older, I realized I was working a little bit harder at digesting what I was eating, and I thought it is not fair to my body to keep doing this. If you are giving it a bunch of crap all the time, it will break down quicker and deteriorate quicker, so I stopped.”
These days, Diaz's low-carb diet consists mostly of healthy proteins such as chicken, fish, steak and shrimp, and grilled vegetables. Cameron also eats sprouts and seeds and avoids white foods such as white bread and pasta. Her preferred breakfast is egg whites, sautéed tomatoes, and steel-cut oatmeal.
Diaz maintains her hot bikini body by exercising daily, combining running, strength-training, and Pilates workouts. She isn't opposed to plastic surgery if it makes you feel better, but said she won't get Botox anymore because she didn't like how it made her look.
For now, Diaz is relishing the present and is moving forward with her usual bubbly optimism. "I’m very much a person who lives in the moment," she said.
