After drawing a fair bit of negative attention over the few extra pounds she gained while out of the spotlight, Alanis Morisette recently appeared in OK magazine looking incredible. She's lost an amazing 20 pounds in a few months, thanks to Joel Fuhrman's Eat to Live plan, but following this diet meant she had to give up a few things -- namely all animal products. Yes, she went vegan.

While changing your life so drastically seems extreme (not to mention really, really hard), she insists it was worth it. "I used to get out of bed in the morning and things were aching, and I just thought, this is what happens when you get into your 30s," she says. "But now I jump out of bed and have so much energy. I feel very alive. I have no more aches and pains, and my allergies are gone, too."

Sounds pretty amazing, but could you go vegan?
