In the 20 long, hungry years between my late teens and late 30s I bought in to virtually every new diet and/or exercise regime that hoved into view, particularly at this most vulnerable time for those of us prone to poor body image - a new year.

Sticking to a diet required me to have a permanently low self-esteem. But happily, I developed other skills beyond a fluctuating weight, eventually building up a different source of self-worth.

I tried the Atkins diet in the Seventies when pregnant with my son, as I didn't want to pile on the pounds. Now, so long as I'm healthy, I don't care what my scales say.

I try my best to be extremely disciplined about my diet.

My mom was always really healthy and cautious about her diet, so I'm not a big sugar guy.

Push-ups, sit-ups, and a strict diet of raisins. That's my plan.

Mexican food is far more varied than people think. It changes like dialects. I was brought up in Jalisco by the sea on a basic diet - tomatoes, chillis, peppers of every size and rice, which is a Mexican staple. The Pacific coast has a huge array of seafood.

I think violence, cynicism, brutality and fashion are the staples of our diet. I think in the grand history of story-telling, going back to people sitting around fires, the dark side of human nature has always been very important. Movies are part of that tradition.

I'm an emotional eater. When I get upset, my diet goes out the window.

I like starting off the new year fresh. I'm excited to see how 2013 turns out. Maybe because I'm an actress and I am always on a diet and fitness program, but my New Year's resolution is to let myself be nice to myself about my body.
