If you’re new to this diet like most people, we know what you’re thinking: Where am I, an athlete, going to get my protein? In a world hell-bent on getting its protein (and spurred on by advertisements and big-agriculture lobbyists), we know this next bit is going to be hard to believe.
If you eat whole foods, you don’t need to worry about getting enough protein. Even when those foods are plants.
Take a look at the elite athletes who excel on a plant-based diet. Remember Michael Arnstein, who ran 100 miles in under 13 hours (a sub-8-minute-mile pace)? In his diet of raw fruits and vegetables, only about 10 percent of the calories are protein. Other vegan athletes such as Brendan Brazier and Scott Jurek have said that they get roughly 15 percent of their calories from protein, and even Chris Carmichael (Lance Armstrong’s nutrition coach for many years) recommends in his book Food for Fitness that most endurance athletes—omnivores and vegans alike—get just 12 to 15 percent of their calories from protein for optimal performance.
