ASDAH Guidelines for Health at Every Size® and HAES® Usage

Since 2011 ASDAH has held the Health at Every Size® and HAES® trademarks. This stewardship has been an effort to protect the community-driven, grassroots development of the Health at Every Size® framework of care from the weight loss industry.

The trademark guidelines, in addition to the HAES® Principles and curriculum, have not been updated for nearly 10 years. It is a top priority of ASDAH’s current leadership team to update the principles and curriculum. As we approach this endeavor, it has become clear that the trademark guidelines, as written in the past, were problematic. They ignored the wisdom of our Black, fat, and disabled ancestors and peers. They have not evolved with new knowledge and important critiques from those most impacted by fatphobia. They have also not protected HAES® from thin-washing and thin- and white-centering. 

The hope that the Health at Every Size® Principles and Framework of Care would continue to be community-centered through a laissez-faire approach has only allowed those with the most privilege to gain huge followings and capitalize off of a diluted and sometimes harmful version of what HAES® could actually offer: health equity for those most impacted by fatphobia. Moving to center Health at Every Size® principles into more liberatory frameworks requires a reining in of the misuse of HAES®.

Those in the HAES® space, especially white providers, are facing a reckoning. We are evolving through a stage mirrored by white feminism and white queer movements. Fat issues are not only white fat issues. Black fat issues are not the same as or less important than white fat issues. And yet, fracturing fat liberation away from Black liberation movements has only made room for some white fat folks. HAES® in particular has only made room for thin white folks. We are committed to moving in ways that re-center and uplift those most impacted by medical anti-fat bias, particularly superfat+, Black, BIPOC, and/or disabled folks.

We believe in community-centered approaches, but only those that acknowledge the inherent power and privilege at play, and constantly work to uplift the experiences of those most impacted by fat-bias in healthcare. Community-led approaches only work when the community is at least as representative of the populations served as the general population. ASDAH Membership as of 2021 was only 51% fat (compared with 74% of the general US population) and less than 10% were People of Color (compared with 45% of the US population and 84% of the global population). 

Fat, Black, disabled, and transgender folks must lead the way. Liberation led by Black, fat women will not leave anyone behind, as white feminism continually does. As we steward the Health at Every Size® Principles into a more radically inclusive and liberatory evolution, we ask for those who espouse HAES® to be in right relationship with us by adhering to the following Health at Every Size® and HAES® trademarks guidelines:
