I’m Goran Pejić, and the identity shift method behind The End of Dieting comes from 35 years of clinical practice – three and a half decades of watching people fight the same exhausting battle.

They’d lose the weight. Then, almost without exception, they’d gain it back – and blame themselves for it. I watched this happen so many times, with so many different diets, that I stopped believing the problem was the diet at all.

The Identity Shift Method: Where It Started

Somewhere along the way, I started reading – not just about nutrition and dietology, but about the psychology behind why we eat the way we do. That search led me to a simple but overlooked truth: no diet works long-term if the person following it hasn’t changed from the inside. You can hand someone a perfect meal plan, and if nothing about who they are has shifted, they’ll eventually drift back to who they were.

That’s the core idea behind the identity shift method. It isn’t a set of food rules. It’s a way of understanding why the rules never stuck in the first place – and what actually needs to change for them to.

I’m 59 now, a former athlete who’s stayed active my whole life, and I’ve watched this pattern from every angle: as a patient who’s made my own mistakes, as a practitioner who’s sat across from hundreds of people trying to make sense of theirs, and as a lifelong student of the science behind it all.

Why the Identity Shift Method Works

Over the years in my practice, I noticed the same story repeat itself constantly. Someone would arrive determined, follow a plan carefully, lose the weight – and then, months later, be right back where they started. It wasn’t a lack of willpower. It was that nothing about who they were had actually shifted. The diet changed. They didn’t.

That observation is what the identity shift method is built around: the idea that lasting change starts with how you see yourself, not with which foods you’re allowed to eat. It’s less about restriction and more about becoming someone for whom the old habits simply don’t fit anymore – someone who doesn’t need willpower to make the healthy choice, because it’s just who they are now.

My daughter is a psychologist, and many of our conversations over the years shaped how I think about the mental side of lasting change – which is exactly what this book is built around. Comparing what I saw in my clinic with what she saw in her own practice helped me connect the dots between physical habits and the identity underneath them. Those conversations, more than any single study or textbook, are what pushed this from an observation into something I could actually put into words.

The Story Behind The End of Dieting

I didn’t write The End of Dieting to add another diet to the pile. I wrote it because, after 35 years of watching this same pattern play out, I wanted to put into words what actually seems to work – not a rigid set of rules, but a way of thinking that makes the rules unnecessary.

I know there’s no shortage of diet books, programs, and influencers promising fast results, and I understand the skepticism that comes with one more voice entering that space. I’m not here to sell a quick fix. What I’ve put together comes from watching real people, in a real clinic, over a real amount of time – not from a marketing formula or a trend I picked up to launch a product.

This isn’t a method I stumbled onto overnight, and it isn’t finished evolving either. Every conversation with a patient, every case my daughter and I discuss, and every bit of new research I come across still shapes how I explain it. What you can find [Inside The Book] is where that thinking stands today – practical enough to use, honest enough to admit it’s still growing.

If you’ve tried everything else and nothing has stuck, this way of thinking about change might finally explain why – and what to do differently. Thank you for taking the time to read this far. If The End of Dieting resonates with you, I’d genuinely like to hear about it.
