PETA's gorgeous new ad featuring 2012 Sexiest Vegetarian Next Door winner Zachary Koval offers living proof that you don't need beef to be buff.

Fitness guru David Barton—whose motto, "Look Better Naked," is something we can certainly get behind—hosted Zachary and PETA for the official unveiling of the ad (which has already been featured on the Men's Health website) at his sizzling-hot eponymous gym in New York City's Astor Place, marking PETA's first-ever gym partnership.

Zachary, a David Barton Gym regular, also presented a free talk explaining the advantages of plant-powered fitness, from the best vegan proteins for bodybuilding to why so many of today's most admired figures—from Carrie Underwood and Natalie Portman to pro fighters Jake Shields and Mac Danzig—are enjoying veggie vitality.

A slammin' body can be sexy, but combine it with a humane (and healthy) heart and you get off-the-charts hotness. Ready to turn some heads and open some eyes? Just do like Zachary and the 2013 Sexiest Vegan Next Door winners, Yerika and John—get fit the vegan way! 

It's time to help PETA select the "Sexiest Vegan Next Door" for 2013. Unlike that other annual sexy competition, the entrants in this contest aren't stars—although they definitely include some heavenly bodies,showing the world the health advantages of a vegan diet in the flesh.

And what's sexier than someone who not only cares about animals and the environment but also takes action to protect both of them?

So be sure to cast your vote today—and then come back on April 15 to help choose your favorites from the finalists! (And if you want to get ready to take part in the 2014 contest, here's how to go vegan in three simple steps.) 

PETA will consider three factors in selecting finalists and winners: votes, enthusiasm and attractiveness. Read the contest details for more info.
