When I was pregnant. I exercised and was healthy, but it was also the first time since I was 14 that I wasn't on a diet.

I box for four hours a week and my diet is pretty healthy.

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

We are also in the process of defining how best to work together with food and other companies to address diet and physical activity factors in order to prevent chronic diseases.

If you can eat 70 percent raw or introduce raw into your diet, it will help your health.
