Feeding Riders of The Tour de France

In this article, here are some quotes from a Hannah Grant, a chef working for a cycling team competing in the Tour de France:

"We don't want to go too hard on the carbs, so they don't gain weight."

"We have a philosophy of using lots of vegetables, proteins, and cold-pressed fats...we try to encourage the riders to try other things than just pasta and bread."

"It's all to minimize all the little things that can stop you from performing 100 percent, that promote injuries, stomach problems, all those things."

Since elite athletes in the grueling Tour de France eat this way, why wouldn't the rest of us eat this way too?
