Fat Bitch: Killing the Willpower Myth by Cat Clark
A Tactical Field Manual for Metabolic Justice & Sovereign Health
The Kitchen Table Conversation

No miracle-cure fantasies. Just truth, science, and strategies that hold up, shared at a kitchen table with people who get it. Ready to join the conversation? Pull up a chair.

Forensic Rebuttal

SHAME WAS NEVER A MEDICAL MANDATE.

In 2005, the cultural phenomenon Skinny Bitch used shame as a mandate and willpower as a weapon. Twenty years later, the results are in: Shame didn't work. Willpower wasn't enough. Fat Bitch performs a scientific autopsy on the Willpower Myth, proving that hunger isn't a moral flaw—it’s a biological signaling system being sabotaged by an ultra-processed food industry.

"This should be The GLP-1 Virgin's Handbook. Invest in this book no matter where you are in your weight loss or maintenance journey."

— EDIE MYERS, GLP-1 User and Reviewer

"This was raw, real, and relatable! I know the subject matter, and it was like I was discussing food, weight loss, diets, drugs, and lifestyle with a bestie."

— KELLY PRAMBERGER, Author and Reviewer

The Voice Behind The Manifesto

WE WERE NEVER BROKEN. WE WERE UNSUPPORTED.

Cat Clark is not a doctor, a clinical scientist, or an influencer selling diet tea. As an outsider to the medical complex, Cat spent decades cycling through fad diets that promised lifelong salvation and delivered only shame, guilt, and metabolic dysfunction.

When the 20th anniversary of Skinny Bitch arrived, she tore into the clinical data to perform a forensic autopsy on the Willpower Myth. She wrote Fat Bitch as an unapologetic field manual for herself, her sister, and every woman ready to stop apologizing for their biology.
