It takes leadership to improve safety. And I started off the movement in my time but the person who has done more over the past 20 to 30 years and who has led it is Professor Sid Watkins.

I've had weight issues all my life. I've been on all the diets: Atkins liquid protein Scarsdale diet. Now I go to the gym often. I'm always on the StairMaster and I do weights.

My biggest regret is putting my body through fad diets - Atkins cleanses the hCG diet.

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 did every diet: Atkins. Cabbage-soup diet. Dean Ornish. But I couldn't live the rest of my life like a rabbit.
