Michele changed her eating habits after reading the 2005 diet book Skinny Bitch — and says long days on set and a vegan lifestyle help keep her in shape.

"My recent diet and exercise routine has been Glee's dance numbers," Michele told UsMagazine.com at PETA's 30th Anniversary Gala in Hollywood. "Our show is so active, and I am a vegan. I'm really proud of that."

But Michele's decision to eliminate animal products from her diet wasn't always such an easy choice.

"Coming from an Italian family, you can imagine [they] couldn't understand. But they respected my decision," she told the June issue of Women's Health, adding that she "always had a problem eating meat."

These days, the Broadway vet is happy to speak out on behalf of animal rights — especially now that Glee has given her a platform to share her beliefs.

"I'm so honored I get to work with PETA every single day," she told Us. "Being on a television show that has such wonderful fans as we do, the fact that I have the opportunity to speak out about the things that I believe in and that maybe someone will listen, I feel, is the biggest honor."
