Laurent Gras. Body fat 2 (t-w-o) percent.You wouldn’t expect to find any chefs on a list entitled "The Fittest Guys in the World for 2010" from Men's Fitness magazine (although a lot of them would do really well on the corollary list of least-fit guys). The names run towards athletes like the Real Madrid soccer star Christiano Ronaldo and Heisman Trophy winner Mark Ingram, Jr., and actors like Sam Worthington. But there is one chef: Laurent Gras of the super-fantastic Chicago restaurant, L20. Gras says he balances his 90-hour weeks in the kitchen by cycling at least one 100-miler on his day off. Here’s what else Men’s Fitness reports: “To maintain his 2-percent body fat (that’s right: T-W-O), Gras heads to the gym five days a week for 30 minutes of jumping rope, an hour of spinning and some lower-body resistance training.” W-O-W. (My only reference for 2 percent involves milk.) For anyone who wants to at least eat like Gras, some of his terrific healthy recipes are at foodandwine.com.
