Why Calories Don't Count invites readers to rethink how we understand food and weight. This science-based guide, written for adults who want a clearer, more sustainable approach to eating, challenges the long-held belief that calories alone determine our success with weight loss. From Cambridge University obesity researcher Dr. Giles Yeo, the book blends accessible explanations with thoughtful storytelling to show why the numbers on a label don’t tell the full story—and why your environment matters. If you’re curious about nutrition and seeking a smarter path to health, this book speaks to you with calm, educational warmth.

In Why Calories Don't Count, the writing is approachable and conversational, designed to make complex science feel clear. It explains that not all calories are created equal and explores how the foods you choose interact with your body’s signals, hormones, and metabolism. The book also examines why popular diets may deliver quick wins but rarely sustain them, and how your environment—such as food availability, routines, and stress—shapes eating habits. The narrative invites you to move beyond counting and toward healthier, more enjoyable choices, presented through practical concepts and real‑world examples.
