Camryn Manheim Here's a lady worth looking up to. Author and actress, Camryn has long suffered from the insecurities of her size, but no more! Her autobiography Wake Up, I'm Fat! was the first to introduce me to fat acceptance, and my self-image and outlook on the world at large (pun intended) has never been the same since. She has made great strides for the cause of size-acceptance, both on the legal show The Practice and her personal life. Pick up her book and change your life.
Margaret Cho Margaret is multi-talented: she's a writer, actress, and stand up comedian, and she extends her talents to embrace and fight for the equality of many minorities, including Asians, women, gays, and people of size. While not technically fat, she's worth a shout out. You may remember Ms. Cho from her show All American Girl from the early 90's, which was ground breaking as the first Asian-American show on TV - although it may not have been a particularly good show over all. After suffering from an eating disordered triggered by ABC's assault on her weight (she nearly died of kidney failure from it), she now campaigns in her stand up comedy against prejudice on all levels, saying that it does little but make us hesitate in life. "I have been a great perpetrator of hate crimes against myself," she writes in her autobiography I'm the One that I Want, "and I'm turning myself in." 
Marilyn Wann This author is on the fore front of the fat acceptance movement. If I hadn't been convinced by Camryn Manheim's autobiography, Marilyn's book, Fat!So? Because you don't have to apologize for your size, would have finished the argument once and for all. If you're still a little shaky on whether or not you believe in this whole size acceptance business, you need to get this book. The woman is nothing less than fierce on every level, and I wouldn't want to get tangled up with her in a debate. 
Lesley Boone You may know Lesley from NBC's Ed as the main character's best friend and a principal of the high school. Originally, the part was described as "the fat girl best friend." Lesley, being used to being cast in such parts, would have none of it. If you tune into Ed you will see a firey, confident character who occasionally scores hotties. Sweet!
Kate Winslett Nobody in their right mind would call the 135 lb. Kate fat, or even plump, but despite this she's undergone extremely severe criticism ever since her star role in Titanic. Regardless of her size, the woman needs a clap on the back for enduring the cruelty, and although it caused her a great deal of pain she's recovered her composure with admirable dignity, proclaiming that she's a "curvy girl" who doesn't look like "American actresses" and she ain't gunna say she's sorry for it. Rock on, Kate, they're probably all just jealous because you got it on with Leonardo Dicaprio.
Kate Dillion This beauty is THE plus-size model, for obvious reasons, and a proud one at that. Her noteriety should be taken as a compliment, because her beauty won her some fame, which brought her to public consciousness, and the media (late night talk shows in particular) tried to skin her alive. She took it all in glorious, swinging strides, saying that she steps on a scale each day to be sure that she hasn't lost any weight. How cool is that?
Mia Tyler You may not know much about Mia, as she's been somewhat in the shadows. Mia is the sister of Liv Tyler, and basically appears to be a plumper, sexier version of her sister. She's a full-figured model, and something of an aspiring actress. You got to give this girl a hand - she's been living in the Hollywood world (which, if you can imagine, is even more thin-obsessed than what we live with on a day-to-day basis) since she was born, being the daughter of Steven Tyler, and yet she still takes pride in her body. That takes one strong individual. Just so you know, she's not a porn star, that picture at left is as daring as she's ever gotten. 
Queen Latifah, music artist and actress, is a role-model in so many ways. It's difficult to get a movie role in Hollywood as a big girl who is not a laughingstock, but she's done just that with movies like Chicago and Bringing Down the House, presenting herself as a strong, beautiful, big, black woman who won't take any crap. You gotta bow to the Queen!
Mo'nique is the star of The Parkers, one of the best-rated sitcoms in African American households, and is also the hostess at the world famous Apollo theater. This sassy comedian, author, and actress is not quiet about her standpoints on the beauty of big women, and in fact published a book on the subject: "Skinny Women Are Evil; notes on being a big girl in a small-minded world", in stores now.
