About the Book

When we believe we take up too much physical space, we often compensate by taking up less intellectual space. We quiet our ideas, hide our brilliance, and put our dreams on hold. Too many women have delayed a career move, stayed silent in a room, or opted out of an opportunity, not because they weren’t capable, but because of how they felt about their bodies.

Do It Fat is an invitation to completely separate your decisions, your actions, and your ambition from how your body looks today, how it used to look, or how it will look in the future. It is a refusal to make your visibility conditional and a hard look at why that is so challenging for so many of us.

As a brand strategist, Sara Chambers has spent years helping entrepreneurs step into the spotlight and own their power. She’s seen how body image can become the invisible barrier that keeps women small. This book examines not just her personal struggle but the cultural and systemic forces that have convinced generations of women to measure their worth in pounds and inches.

Infused with personal stories, sharp cultural critique, and unflinching observations, Do It Fat exposes why women hate their bodies and how that hatred robs them of visibility, voice, and impact. It is an unapologetic guide for every woman who has delayed her dreams because of her body.

Praise for Do It Fat

  • "Do It Fat is a bold, unapologetic celebration of bodies that challenges the myths and stigma so many of us carry. Sara’s writing honors autonomy, joy, and well-being while refusing to center weight as the measure of health or worth. At the same time, she centers the lived experience of bodies in a way that is honest, vibrant, and unflinching, without asking anyone to erase or diminish their own body. This book is a powerful reminder that everyone deserves space, physically, socially, and emotionally, to thrive as they are."

  • "Do It Fat leans into the “both” and the “and” of body image, diet culture and beauty standards and takes into consideration all the nuance that is often left undiscovered or purposely avoided. Sara’s work is raw, unfiltered, based on both lived experience and pertinent research - the necessary blend that separates flat opinion pieces from robust, thought-provoking literature. This work highlights how mainstream diet and fitness culture makes us (often, women) lose our sense of self, health and worth and digs into the complexities of body image work while navigating body changes. This book is the mirror we all need to finally see the beauty and benefit of living our lives on our terms in whatever body we have, today. "

    Pia

  • “I finally understand that wanting to feel good in your body isn’t a betrayal, AND showing up in the body you have today is the deepest form of agency, selfactualization, and permission.”

    Shaina

  • “This book is a liberating guide back to self-trust, self-acceptance, and the courage to live unapologetically in the body and life you have. And want. A powerful read for women, founders, and anyone ready to take up the space they deserve.”

    Roseann

  • “Do It Fat is one of those books that gives language to things you have carried for years but never knew how to name. Sara writes with such clarity and compassion.”

    Kristen

  • "This book is the softest, yet boldest invitation to rethink the relationship you have with your body. Sara offers a heart-filled and grounded guide to untangling the twisted ideals our culture holds so tightly."

    Erica

  • "Do It Fat is the kind of book that lands in your hands at exactly the right moment — the moment you’re tired of negotiating your worth with the size of your body. "

    Alessia

  • “I tore through this book in just a few days because it didn’t just speak to me…it spoke for me. Do It Fat captures something I’ve never seen expressed with this level of honesty, nuance, and emotional intelligence: the ways we quietly shrink, edit, or postpone our own lives because of how we feel in our bodies.”

    Colleen

  • "This is so much more than one woman's perspective on embracing life in her own, unique and amazing body. It's full of history, facts, heartbreaking truths about the way society hasn't given women a fighting chance.”

    Ashley

  • “I didn’t realize how deep the conditioning ran until this book laid it out with receipts, research, and that exact blend of warm, compassionate, tough love I didn’t know I needed. If you’ve ever tied your worth to your weight, read this. Then hand it to every woman in your life.”

    Erika

  • “Sara has this rare ability to combine cultural critique, lived experience, and piercingly clear storytelling in a way that makes you feel both seen and challenged in the best way.”

Excerpt From Chapter One: 

Because this moment, this particularly messy, layered, tender moment, is the one no one talks about. The one where your body is changing, and the world starts responding to you differently, and you’re trying to hold it all without losing yourself.

For me, being fat was a kind of armor. A protection. A buffer between me and the world. As the weight has come off, so have the layers. The protection is gone. And while I’m proud of the healing, I’m also feeling the sting of exposure.

“You look amazing” isn’t neutral. It’s not just about how I look now. It’s a commentary on how I looked before. And whether people mean it or not, the message that gets communicated is: now you’re more acceptable.

I feel protective of my previous self, the one who had the audacity to take up space when the world said she shouldn’t. The one who wore bright colors, showed up in rooms, took the mic, and didn’t wait.

Because here’s what I know: body shame doesn’t just hurt our feelings. It robs our futures. It convinces us we can’t show up until we’ve earned it. And I’m done with that.

This book is my way of making sense of all of it. A way to grieve the time I lost, celebrate what I learned, and carve out space for every version of me, then, now, and next.

The Cost of Body Shame

A 2023 study in the UK found that 62% of women have delayed a major opportunity—career, relationship, or public visibility—because of how they feel about their body.

In the U.S., 85% of women say they have opted out of life activities like going to the beach, speaking in public, or applying for a job because of appearance anxiety.

These numbers aren’t just statistics. They represent millions of dreams deferred, voices silenced, and lives lived smaller than they could be. Do It Fat exists to break that cycle.
