The talk show host, 54, is going vegan for a 21-day detox plan. In addition to swearing off animal products, Winfrey and three pals from her production company are also banning caffeine, sugar, gluten and alcohol.
What inspired the massive menu overhaul? The small-screen queen credits Kathy Freston's book Quantum Wellness and online sessions with Canadian motivational speaker Eckhart Tolle. (She's also getting help from chef Tal Ronnen.)
And as the detox progresses, Winfrey will be blogging the diet's ups and downs. (Her Web site will also include meal plans and recipes.)
"This 21-day cleanse gives me a chance to think about [eating] differently and see what my attachments are to certain kinds of foods – and what I'm willing to do to change," she wrote on Sunday (day one). "Don't know if I'm going to feel better or worse, but I'm willing to try to see if my body at least feels differently."
So far, Winfrey isn't missing her meat.
"I had been focused on what I had to give up – sugar, gluten, alcohol, meat, chicken, fish, eggs, cheese. 'What's left?' I thought," she wrote on day two. "Apparently a lot. I can honestly say every meal was a surprise and a delight, beginning with breakfast – strawberry rhubarb wheat-free crepes."
