Forget the whole high-fat Atkins low carb thing. That is so 2001. These days its all about detoxing and going clean and vegan.

Alanis Morissette just lost 20 pound using old vegan stand-by diet Eat to Live. FYI – this diet is alot like the one Dr. Ian promotes on Celebrity Fit Club.

“I feel like a 12-year-old!” Alanis Morisette tells OK! of losing 20 pounds on her vegan diet, inspired by Eat to Live by Dr. Joel Fuhrman. “I’m back to what I was born to be, at my best. 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. But now I jump out of bed and have so much energy; I feel very alive.”
