Cat Clark writes for the women who did everything right and were still told to try harder. Her work sits where endocrinology meets the dinner table: GLP-1 pharmacology, trauma, insurance denials, and the thirty-year shame campaign that filed all of it under willpower.
She is the author of FAT BITCH: Killing the Willpower Myth (unLit Publishing, October 15, 2026) and the creator of the Shared Agency Framework, the operating manual for patients who are done being managed and ready to run the file themselves.
FAT BITCH: Killing the Willpower Myth performs an evidence-based autopsy on the era that weaponized willpower, then hands over the science, the scripts and the tools. Hardcover, paperback, ebook and audiobook, plus the full-colour Anti-Diet Workbook.
See every edition →The Shared Agency Framework (SAF) is the clinical methodology underneath the book: Biology, Environment, Action. It is published open source at Her Metabolic Health, with the protocols, the sourcing and the research archive.
hermetabolichealth.com →Diet culture wanted us isolated and ashamed. Bitches & Besties is the answer: a forum, a patient-vetted directory of doctors who do not flinch, monthly live Q&As, and downloadable tools that cost nothing.
Find your besties →For thirty years we were handed the same prescription: eat less, move more, want it badly enough. When it failed, and it always failed, the diagnosis was us. Then the science caught up. Metabolic adaptation is real, food noise is real, and willpower is a squirt gun against a forest fire.
Cat Clark's work translates that research into something we can actually use on a Tuesday: what the medication does and does not fix, what to say when a relative asks what we have been doing, how to file a prior-authorization appeal, and how to protect muscle while the scale moves.
She is not a doctor. She is a Lifer who got tired of the bullshit, read the studies, and wrote down what she found.
