Tim Bradley used a vegan diet to power his victory in a welterweight championship fight at the MGM Grand in Las Vegas June 9.

Bradley’s opponent, Manny Pacquiao of the Philippines, had been undefeated since 2005. The powerful 33-year-old, who defeated Oscar de la Hoya in 2008, was a 5-to-1 favorite over Bradley. But Pacquiao, whose nickname is “Pac-Man,” the video game character who eats anything in his path—was no match for the vegan.

Tim “Desert Storm” Bradley, the American underdog, used a vegan diet to turbo-charge his training regimen, following in the footsteps of many other athletes who use a vegan diet for better energy and quicker recovery between training sessions.

Ultramarathon champion Scott Jurek crushes the competition with his vegan diet, as do long-distance running marvels Brendan Brazier and Rich Roll. Former Mixed Martial Arts champion Mac Danzig made the regimen popular among fighters as he rapidly dispatched the competition.

Many athletes have drawn inspiration from the most powerful animals—bulls, stallions, and elephants—all of whom eat entirely vegan diets—while a pussycat is a heavy meat-eater. For elite athletes, an animal-based diet is similar to smoking, constricting blood flow and reducing endurance.

The victory gives Bradley the welterweight championship and a jaw-dropping 29-0 record.

PCRM recently launched the VegRun program to help both amateur and professional athletes to power up their training regimens.
