Can I be a competitive athlete on the Engine 2 Diet?

Just ask Tony Gonzalez, the 247-pound tight end for the Kansas City Chiefs football team. For health reasons, Tony changed his diet after signing a five-year contract extension, making him the league’s highest paid tight end, and went on to break the NFL record for receptions by a tight end in 2008. His teammates have nicknamed him China Study after T. Colin Campbell’s book of the same name, which Gonzalez studied before changing his diet—and which you will soon be reading about.

Ask Ruth Heidrich, who in 1982 was diagnosed with metastatic breast cancer and cured herself by eating a low-fat, plant-strong diet. She has since won more than one thousand triathlons. Or ask Salim Stoudamire, the plant-eating point guard for the NBA Atlanta Hawks, who says that by the fourth quarter, when most players are starting to fade, he’s picking it up a notch. Or ask Martina Navratilova, the world’s winningest tennis player, who serves up plant-based foods exclusively. Or ask plant-devourer Dave Scott, my hero and six-time winner of the famed Hawaii Ironman triathlon.

Or better yet, try going plant-based yourself and see how much your own athletic performance improves.
