You've seen them – those lean and lanky, fit people who credit their ability to maintain that look to eating moderate amounts of a well-balanced diet combined with a moderate amount of exercise.
They're the people who can eat a few bites of the yummiest dishes and say they've had enough. It's a trick I've yet to learn.
I like to run marathons, so moderation is something that doesn't come naturally to me. I put in a lot of kilometres in training – last week, almost 110. That's good and bad. I'm burning a lot of calories, but also developing a substantial appetite.
Think Michael Phelps – the diet, not the bong.
