It's really important to remember that most people in the public eye are human for a start and a lot of things that you read in the media get slightly misconstrued and manipulated.
I tried the paleo diet, which is the caveman diet - lots of meat. And I tried the calorie restriction diet: The idea is that if you eat very, very little - if you're on the verge of starvation, you will live a very long time, whether or not you want to, of course.
For me the question was, do I want my paycheck to be dependent on how other people think I look?
