It's been almost three months since Mike Tyson announced that he had gone vegan — a drastic change in diet that many thought was a publicity stunt for the former heavyweight champion.

It was hard to believe it was for anything but all the wrong reasons. After all, Tyson had just come under fire from PETA for his new reality pigeon racing TV series, "Taking on Tyson", on Animal Planet. Surely, he was just trying to get a little attention with the whole "vegan" thing, right?

Or not.

“It’s been eight months with this vegan stuff," Tyson recently told Details magazine, "but I get these explosions of energy. I don’t know how long they last, but they’re like explosions. So powerful.”

“I ate, like, the tiniest piece of meat, and I woke up violently sick,” he added. “It was vicious pain. I was throwing up. And I realized meat’s become a poison for me now.”

At the time of his vegan coming-out party, Tyson told USA Today that he was looking for absolutely no drama in his life — and looking forward to sharing his love of pigeons with the world.

"I’m honored to be a part of this monumental show on Animal Planet,” says Tyson, whose first-ever fight as a child was in defense of his birds. “I feel a great pride acting as an official representative for all the pigeon fanciers out there. I want people to see why we love these birds. It feels good returning to the rooftops of the city where it all started for me — New York.”

The series will debut on Animal Planet in early 2011.
