" Celebrities dictate everything: fashion, hairstyles, where to eat, even what to eat. In the recent history of Oprah (yes, she is so important she gets her own section of history) she has been promoting what people should not be eating - namely meat, dairy or any other animal product. Yes, the new thing Oprah loves: veganism. On Feb. 1, she and 378 Harpo employees began a week of attempting to be completely vegan, in response to a visit from Kathy Freston, best-selling author of the Veganist and a vegan for seven years. Oprah was among 300 of the 378 who made it successfully through the vegan week. Together they lost a total of 444 pounds and, according to Oprah&amp;#039;s website, used a &amp;quot;record amount of toilet paper.&amp;quot; Though Oprah herself will not remain vegan, her longtime partner, Stedman Graham, has expressed interest in sticking with it.

Katie Holmes was recently spotted dining out with her stepdaughter, Isabella Cruise, at the Vancouver Vegan eatery, Gorilla Food. Ellen DeGeneres and wife Portia De Rossi, both vegans, celebrated Ellen&amp;#039;s Jan. 26 birthday with a vegan red velvet cake. Last September, former President Bill Clinton experimented with veganism in order to lose weight and improve his heart health. And his daughter, Chelsea, recently had a vegan and gluten-free wedding, complete with a pistachio rose water wedding cake. Some other notable famous vegans? Glad you asked.  Bryan Adams Avril Lavigne Sandra Oh Heather Mills - The former Mrs. McCartney is quite the vegan entrepreneur. She owns a VBites, vegan restaurant in Brighton, England. She also own Redwood Wholefood Company, a vegan food firm. Woody Harrelson (obviously) Andre 3000 Mike Tyson - Though there was a time when Tyson had a taste for human ear, the prize fighter now follows a strictly vegan diet. Daryl Hannah Prince Russell Simmons - Music mogul Simmons has been a vegan for ten years. His reasoning for ruling out meat is morally fueled rather than based in health. In a recent interview with CNN he discussed the &amp;quot;15 billion suffering farm animals. And I don&amp;#039;t want to participate in it.&amp;quot; He is partial to a spicy tempeh dish. Liv Tyler k.d. Lang Weird Al - The king of polka-fueled parody became a vegan in 1992 after reading Diet for a New America. He is an accepting vegan and is unopposed to performing at meat-centric events like the Great American Rib Cook-Off. When asked how he rationalized that he responded, &amp;quot;The same way I can rationalize playing at a college even though I&amp;#039;m not a student anymore.&amp;quot;  Have you ever gone vegan to lose weight or for other reasons?
