The whole article is a fat riot ("Fat Liberation", fat revolution):

However, their lack of understanding or belief in a shared struggle, or what we might now call an intersectional analysis, meant that many fat folks were shut out of fat activism. Let’s take a look at the impact of race as an example. Many activists associated with NAAFA and other mainstream branches of the movement tended to be single-issue activists; they were reluctant to incorporate other social justice issues into their activism as they thought it would detract from their goals. While fat, many of these activists lived with the privileges of being white, heterosexual, cisgender, middle or upper class, and/or American; they had very little incentive to incorporate other struggles into their activism. This resulted in the voices of people of color, among others, being left out of the mainstream fat acceptance movement. At the same time, they also assumed that communities of color were more accepting of fatness and so this kind of activism was unnecessary in those communities. Their lack of intersectional analysis meant that they did not understand the ways that fat-phobia showed up across racial groups.

You may didn't know it, but the black slaves in America ate so well and worked so little (due to laziness) they were typically fat:

Further, in the American context, anti-fat bias and fat-phobia are deeply rooted in white supremacy and anti-blackness. Sabrina String’s book Fearing the Black Body: The Racial Origins Of Fat Phobia argues that as color became more complicated because of rape and miscegenation in early America, body size became another way of understanding who was enslaved and who was not, and, by extension, who was Black and who was white. This product of white supremacy became intertwined with the deeply patriarchal project of keeping women literally and figuratively small. This put white women in the position of having to remain slender in order to recoup the benefits of correctly performing their gender and race. Further, this early period solidified cultural associations between laziness, fatness, and Blackness which have carried through mostly unchanged to the current day. These messages have also become internalized within Black and other communities.
