November 1 is World Vegan Day.
From a healthy decrease in cholesterol, blood pressure, and heart disease risk to weight loss, there seem to be plenty of health benefits to ditching dairy, meat, and eggs.

Surprisingly, many top athletes - including world champions, martial artists, and an Olympic weightlifter - don't seem even slightly worried about getting enough protein from their vegan diets.
Business Insider has compiled a list of world-class vegan athletes who are at the top of their game, and have a fully vegan lifestyle to thank for it.
From soccer players to weightlifters, and basketball stars to a prominent racing champion, scroll on to discover 19 athletes who are vegan - and what made each of them switch to a plant-based diet.
