Eating 2.0: How to Eat Confidently in an Ultraprocessed World

Do you feel powerless around food, no matter how hard you try?

In a world designed to keep us eating—where hyperpalatable, ultraprocessed foods hijack our biology and overstimulate our appetite—diets, rules, and intuition no longer work. But even when eating well feels impossible, there is a new way forward.

Drawing on Internal Family Systems (IFS) therapy and nutrition psychology, Jeff Siegel's Eating 2.0 offers a revolutionary approach to help you break free from guilt, restriction, and mindless eating. Whether you're a chronic dieter, an emotional eater, or can't stop thinking about food, this book will change how you understand hunger itself.

You’re not just one eater—you’re a whole inner family, each with its own voice at the table:

• The Survival Eater, who protects you from hunger and deprivation.
• The Pleasure Eater, who seeks joy, comfort, and irresistible flavors.
• The Social Eater, who craves belonging and fears judgment.
• The Strategic Eater, who strives for control and perfection.

With practical tools, real-world scenarios, and science-backed insights, Eating 2.0 empowers you to lead your Inner Eaters so you can eat intentionally, even in a toxic food environment.

This isn't another diet. It's a total eating upgrade: a new relationship with food, yourself, and social pressures that derail your best intentions.

In this insightful book, wellness coach and Harvard teaching fellow Jeff Siegel provides a step-by-step guide for identifying industry hijacks, trusting yourself around food, and thriving in today’s complicated eating environment.
