The Queen of Talk is turning her back on caffeine, red meats, and sugar as she and three Harpo companions take on a twenty-one day Detox Diet. According to a post on Oprah’s official blog, the girls were inspired by Kathy Freston’s new book Quantum Wellness; they will be documenting the effects of their experience as they progress.

“Wow, wow, wow! I never imagined meatless meals could be so satisfying.” she wrote. “I had been focused on what I had to give up — sugar, gluten, alcohol, meat, chicken, fish, eggs, cheese. ‘What’s left?’ I thought. Apparently a lot. I can honestly say every meal was a surprise and a delight, beginning with breakfast — strawberry rhubarb wheat-free crepes.”

“So this first day wasn’t hard at all. For breakfast, I had steel-cut oatmeal with fresh blueberries, strawberries, chopped walnuts and a splash of soy milk and some agave nectar. For lunch, chunky mushroom soup with wild rice and pecans. As a snack, a handful of roasted almonds. And for dinner, a baked potato drizzled with olive oil, salt and pepper with a salad of shredded lettuce, cranberries, pine nuts and tiny orange slices with a vinegar and oil dressing.”
