Lance Armstrong Going Plant-based

I've wondered how long this would take—for someone as smart as Lance Armstrong to recognize that he should be eating a plant-based diet. He is now two-thirds of the way there.

Armstrong is friends with Rip Esselstyn, a former triathlete and founder of the Engine 2 (plant-based, vegan) diet—and son of Dr. Caldwell Esselstyn whose plant-based approach to preventing and reversing heart disease is healing former president Bill Clinton's heart.
