Eating: solved from first principles.

Finally, a diet rooted in logic, not dogma.
Welcome to the greatest book ever written on how to eat.

Backed by data. Powered by logic. Proven to work.

The physics of hunger—and the math of satiety.

This is eating—reengineered.

Not another diet: a new law of eating.

Satiety per calorie: the only metric that matters.

This Book Solves Eating.

Most diet books tell you what to eat. This one explains why.

Rooted in first principles and built on a foundation of logic, data, and human biology, Satiety Per Calorie is the clearest, most practical guide ever written on how to eat for sustainable fat loss.

It doesn’t push a fad or ideology—it uncovers the universal laws that govern hunger, fullness, and calorie intake.

Once you understand satiety per calorie, you’ll see every food choice differently.

This is more than a book—it’s a lens that will permanently change how you think about eating.

Hi, I'm Ted Naiman.

[I'm the author.]

I’m a primary care doctor who’s spent over two decades helping patients lose weight, reverse chronic disease, and improve their metabolic health. But I grew frustrated with how confusing and ineffective most diet advice had become—conflicting fads, tribal nutrition wars, and gimmicks that never addressed the root cause of overeating. So I went back to first principles. I built a new framework based on satiety per calorie: a simple, powerful way to understand which foods keep you full with fewer calories. I wrote this book to share what I’ve learned—not just from clinical practice and research, but from thousands of real-world success stories. My goal is to make eating for fat loss effortless, logical, and sustainable for everyone.
