I'm pretty careful about what I eat (6'2", 166 lbs). No real secrets... I eat lot's of lean meats, fish, veggies, pasta/grains, nuts, and fruit. I probably eat vegetarian dishes 10 times a month. I tend to like Mediterrean style dishes, very healthy with lot's of wonderful flavors. I avoid/don't eat anything fried. Also no soda. I'm a bit of a cycling nut, so it's not uncommon for me to burn 7000 calories a week during the season. That said, I have to eat really well to keep the engine going.
