I played a round of golf at the Maroon Creek Club in Aspen with British Open and TPC Champion Justin Leonard. I observed Justin order a Ahi Tuna cup without the Ahi, which I thought was strange. When I asked why, Justin said he prefers healthy snacks and avoids protein and fats during a round of golf. As I recall, Justin shot 64 that day!
Just observing what Justin and his wife Amanda eat inspired me to change my diet. I do not eat as pure as they do but I lost 30 pounds three years ago by eating primarily healthy foods and avoiding sugar and fried foods.
