We all believe in science, right? So the scientific method goes: hypothesis, experiment, theory. Right? So you have a hypothesis that cyclists should be fruitarians and need only 2-3% protein in their diet. Is that right? So I challenge you to prove your hypothesis through experiment. Work up to a monthly mileage of at least 800 miles for a couple of months. Then take it easier for a week and ride a double century in under 12 hours. All the while eating only fruit. Let us know how it goes.

What I propose is not even hard. It's nothing unusual for a sport cyclist. Pretty much anyone can do it, and tons of people do. Except for the fruit part, of course. Oh - no pretzels or chips, either. You won't want to get too much salt.
