I've never been bashful to say that I'm not really interested in Formula One. When I lived in England it's all I wanted to do and I thought that anything else would somehow be a compromise to my dreams. But then when I came back to the States I realised how much I loved being back in the States.

Men don't come up to you to just talk. We come up to you with a plan. We're looking across the room at you and we don't care about your hopes and dreams. We don't care about what your future holds. We saw something we wanted.

I just write what I wanted to write. I write what amuses me. It's totally for myself. I never in my wildest dreams expected this popularity.

If you continually diet you are putting your body in a quasi-famine situation. It slows your metabolism down and breaks the thermostat. Diets don't work. They don't help you understand why you're eating more than your body wanted in the first place.

I was a vegan for two years and I really enjoyed it. Then I got to a point in my life at which I wanted to do something else so now I'm a vegetarian. You should make your diet one that best fits you and how you feel. Listen to your body. The most important thing is to exercise drink lots of water and take really good care of yourself.

The one thing I like about 'Playboy' is they don't have the anorexic look. The women are voluptuous. So I didn't really want to diet. I just wanted to tone up.

I put on fifteen pounds of muscle so that was a lot of eating chicken and a high protein low-carb diet. Also a lot of heavy lifting and a very different kind of training with an ex-navy SEAL guy who wanted to kill me every time I got with him. In a good way.

I still indulge in a glass of wine or chocolate - treats are mandatory. Without deviating from the day-to-day healthy diet once in a while it wouldn't be sustainable for me and that's what I wanted: an approach to eating to last my entire life.

I do what I love to do at the moment. If I wake up tomorrow and decide I want to dance that's what I'd do. Or design clothes. I think I'd throw myself into whatever I'm doing now. It's not about abandoning what I was doing before or giving up. It's about knowing that if I die tomorrow I lived the way I wanted to.

When I started this project I was a young architect. I was very apprehensive about any changes to the design. Whether I wanted to or not I learned that you can accept some changes to its form without compromising its intent. But it's a leap of faith that I didn't want to make initially - to put it mildly.
