The Research Post

This is the Weight and Healthcare newsletter. If you like what you are reading, please consider subscribing and/or sharing!

I often refer people to the resource and research list of the HAES Health Sheets, which is a project I co-created with Dr. Louise Metz and Tiana Dodson. In addition to the list, the sheets are diagnosis-specific, weight-neutral practice guides for practitioners, patients, and advocates. I recently got a request from a reader to create a post here with the research list that they could send people to, so here it is. This will be a living page that I update as new resources come out. If there are studies you feel are missing, please don’t hesitate to let me know! It’s divided into two sections, support for weight-neutral care and issues with weight loss/dieting as a healthcare intervention.

Content note: Many of these studies are written from a weight-centric paradigm, using terms that pathologize body size, and advocate for the eradication of fat people.

In addition to the studies below, I have some research round-up posts that may be helpful:

*Note on language: I use “fat” as a neutral descriptor as used by the fat activist community, I use “ob*se” and “overw*ight” to acknowledge that these are terms that were created to medicalize and pathologize fat bodies, with roots in racism and specifically anti-Blackness. Please read Sabrina Strings: Fearing the Black Body – the Racial Origins of Fat Phobia and Da’Shaun Harrisons Belly of the Beast: The Politics of Anti-Fatness as Anti-Blackness for more on this.
