Fat feminism or body-positive feminism is a form of  feminism that merges with  fat acceptance movement and specifically addresses how  misogyny and  sexism intersect with  sizeism and  anti-fat bias. Fat-positive feminists promote acceptance for women of all sizes. Fat feminism originated during  second-wave feminism. Fat feminism has come a long way and is still expanding. In this, now third-wave of feminism, fat feminists are fighting for their independence to just be happy with their bodies and wear what they want without receiving criticism for it. Sizeists have negative opinions about people who are "over-weight" such as being lazy, eating unhealthy foods more often than they should, and think that people who are over-weight shouldn't wear certain types of clothing ^[1]. Fat feminism is also fighting for a chance to be recognized in the media, in fashion magazines, in runway shows, in television, and not just where it concerns people overweight participating in shows like "The Biggest Loser." It's important for individuals who are overweight to be represented positively in the media and made to feel special, not just made examples of what not to be. It's important for ALL body types, ALL ethnicities, ALL sexualities, ALL gender identities to be represented in the media.

A theory presented by Michele Foucault in The Perverse Implantation suggests that people become "subjects" when they are considered outsiders or become outsiders. This is referred to as interpellation ^[2]. Due to interpellation, industries are built to fix such subjects. This is much like the dieting industry, built to help people overweight become "normal" which in a society such as this, the goal is to be thin or curvy, not fat. Weight Watchers, Nutrisystem, DetoxTea, surgical weight loss options, are all tailored towards individuals to lose weight, which is also what fat feminists and body-positive activists are completely against. Laura S. Brown, author of Fat Oppression and Psychotherapy, examines that being fat isn't unhealthy. The standards that we hold over-weight individuals to, is what's unhealthy for these individuals. Bulimia, anorexia, depression, anxiety, etc., are all brought on because of the standards that society has over those who are considered outsiders to what's normal ^[3].

Fat feminism and the related  fat acceptance movement originated in the late 1960s during which  second-wave feminism took place. During the late 60s and 70s, activists such as Sara Fishman, Dr. Franklin Igway, Judy Freespirit, Aldebaran, and Karen Jones, now known as Karen Stimson, emerged. In 1973, Fishman and Freespirit released Fat Liberation Manifesto in which they opposed size discrimination as sexism. Their movement was met with mixed reactions during the 60s, the same decade when very thin models became fashionable. Some of the feminists, such as  Gloria Steinem and  Jane Fonda active during the decade believed that removing traits of "femaleness" was necessary to gain entrance to a male-dominated society. Activists continued to hold demonstrations and continued their course of action. When fat feminists did not get support from  National Organization for Women, they founded organizations to advocate size acceptance, such as Fat Underground (opened up by Judy Freespirit and Aldebaran) ^[4], The Body Image Task Force (Santa Cruz) and The Body Positive.

During the 80s, the movement had mixed success. More organizations and publications against  size discrimination were founded. The first fat feminist book, Shadow on a Tightrope: Writings by Women on Fat Oppression, by Lisa Schoenfielder and Barb Wieser was published in 1983. The first issue of Radiance: The Magazine for Large Women was published in 1984. Clothing brands and fashion magazines were founded during this time that targeted a plus-size audience. Fat feminists continued to sue diet programs for fraudulent claims. However, the popularity of the diet industry did not wane as it was boosted by the fitness boom during the 1980s. By the late 1990's, Americans were spending approximately $40 billion on diet products and programs.

In the 1990s, fat feminism was officially supported by  National Organization for Women when the organization adopted an anti-size discrimination stance with no dissenting vote, and started a body image task force. In 1992, Mary Evans Young, a size-positive activist in England, launched  International No Diet Day (INDD) which was planned as a picnic. Due to the rain, her plan failed, and the celebration was held indoors instead. In 1993 many American feminist groups joined in and 25 states participated in INDD's second annual celebration.  International No Diet Day continues to be observed on May 6 each year.

In 1993, the  California Supreme Court ruled in favor of Toni Cassista who filed a lawsuit against Community Foods, a store in  Santa Cruz, California when she was not hired because of her size. This put an end to work discrimination based on weight in the state of California.

During the 90s the  zine movement, the  riot grrrl movement, and the  Fat Liberation movement converged for many young activists, resulting in the publication of numerous fat feminist zines. Among these publications were Fat!So?: for people who don't apologize for their size, by  Marilyn Wann, I'm So Fucking Beautiful by  Nomy Lamm, and Fat Girl: a zine for fat dykes and the women who want them, produced by a collective in San Francisco from 1994-1997. In 1996 Toronto-based activist and performance art troupe  Pretty Porky & Pissed Off (PPPO) was founded by  Allyson Mitchell, Ruby Rowan and  Mariko Tamaki. PPPO grew to include other members and worked as a collective until 2005 publishing their zine series, Double Double.  Nomy Lamm was named by  Ms. Magazine as a "Woman of the Year" in 1997, "For inspiring a new generation of feminists to fight back against fat oppression." In 1999  Marilyn Wann expanded her zine into the book Fat!So?: Because You Don't Have to Apologize for Your Size. In 2005, former Fat Girl collective members Max Airborne and Cherry Midnight published Size Queen: for Queen-Sized Queers and our Loyal Subjects.

The 2000's saw an increase in internet feminism and internet fat activism, which have often converged. The fat acceptance  blogosphere has been dubbed the "fatosphere" and has enjoyed some positive publicity in mainstream publications. Kate Harding and Marianne Kirby, who are prominent fat bloggers, released a co-written self-help book in 2009 called "Lessons from the Fat-o-sphere: Quit Dieting and Declare a Truce with Your Body", which has 27 chapters devoted to different topics, including body positivity,  health at every size, and  intuitive eating. In 2005 Linda Bacon conceived the  Health at Every Size belief system, which rejects dieting and the weight-based paradigm of health. This has been adopted by many fat feminists. Beth Ditto, frontwoman of punk band  The Gossip, who is vocal about fat acceptance, attained celebrity in the mid-2000s with the popularity of her band's 2006 album  Standing in the Way of Control, which has raised awareness of the movement.

Shortly after Barack Obama had started his term as President, the first lady, Michelle Obama, began a campaign called "Let's Move" to draw attention to obesity in America and encourage people to work out, eat healthy and lose weight as a result in 2010 ^[4]. An additional example of societal standards of individuals over-weight.

In May 2015, America met the "Dancing Man." The man, Sean O'Brien, is an over-weight man that loves to dance. A twitter user posted a picture of him dancing and another photo of him looking upset, captioning the photos with "caught this specimen dancing last week, he stopped when he saw us laughing." Soon after this was posted, Cassandra Fairbanks started a movement to get O'Brien to come to America and dance with the big leagues in Los Angeles where he was celebrated ^[5].

At the beginning of 2016, Mattel released "Curvy Barbie." This line of Barbie's included dolls that were all shapes, sizes, and a select few of different ethnicities ^[6].

At the beginning of 2017, there was a new trend for fat feminists and body-positive activists to take control of. The #Don'tHateTheShake videos posted all over social media, were about both fat men and women stripping down to their undergarments and dancing to upbeat music as if they were at a dance club. This was created by Melissa Gibson, but has gained traction because of Megan Jayne Crabbe, who spreads body positivity all over social media to her large follower count.Crabbe has recently published a book about body positivity, that has yet to be published in the United States, called Body Positive Power.

Many of the authors in Shadow on a Tightrope: Writings By Women on Fat Oppression are lesbians, and many were involved in  lesbian feminism. Their experience of fatness is different from that of straight fat women because of their experience of combined discrimination based on their sex, size and sexual orientation.

Fat women of color have a different experience than fat white women because of their intersectional experiences of not only size discrimination and misogyny, but racism as well. Women of color also need to be represented in the media. People of color in general, overweight or not, are portrayed negatively in television shows, movies, and even major news channels ^[7]. Some examples of women of color in the media is bell hooks, Lauryn Hill, Sonya Renee Taylor, and Gabourey Sidibe ^[8]. Citations
