Inspired by Los Angeles yogi and best-selling author Kathy Freston, Oprah decided to go Vegan, at least for 21 days.

The daytime deity took on the three week detox challenge this week after Freston appeared on a makeover-themed Oprah episode and explained that eating consciously (ahimsa toward animals and the planet) is one important way to honor the mind, body and spirit.

Freston, who is promoting her new book Quantum Wellness: A Practical and Spiritual Guide to Health and Happiness, also lent Oprah her chef Tal Ronnen, which certainly should make Oprah's efforts to wean herself of animal products (and caffeine, sugar, gluten and alcohol too) an easier task. Who wouldn't want their own Vegan personal chef, especially one who whips up strawberry, rhubarb wheat-free crepes?

Of course, Oprah is blogging about the whole experience and Ronnen is posting some swell recipes as well.

While the detox feels a little like a stunt (especially since the diet is being promoted mostly as a device to "take 10 years off your looks"), there's no doubt Freston is doing a stellar job of bringing the concept of conscious eating to a huge, mainstream audience.

Hey, if Oprah can help Freston's book soar to the number 1 spot on Amazon, there's no telling what she can do for Veganism.
