Introduction

Picture sitting in a clinic chair, feeling as though you’ve tried every diet under the sun, only to end up heavier. That scenario played out daily for the author, who listened to countless patients’ struggles. Over time, it became clear that simple “eat less, move more” advice was not enough.

Behind every frustrating weight loss attempt lies a sophisticated biological system. Fat cells, hormonal signals, and even stress levels orchestrate how our bodies respond to food. As you read these pages, you’ll see that obesity isn’t about willpower; it’s about biology.

This summary sheds light on the hidden mechanisms driving our relentless appetite, especially how our bodies stubbornly fight to keep us at a particular weight—often higher than we’d like. The good news: there are ways to persuade the body to change its set-point.

Expect personal anecdotes from real patients, fascinating new science, and a clear road map for long-lasting weight control. The journey starts by shaking off guilt, shame, and impersonal dieting rules. You’ll gain knowledge, confidence, and renewed hope for a slimmer, healthier you.

Your struggles with weight aren’t a failure of willpower, but a clue that your body’s set-point needs resetting.

Why Our Bodies Resist Weight Loss

A key discovery about obesity is that our bodies sense attempts to lose weight as a potential threat. When you diet severely, hormones ramp up hunger and slow metabolism, like a thermostat refusing to budge. This is the concept of negative feedback: the body defends itself against big changes.

Studies from prison inmates and contestants from radical weight-loss TV shows highlight the phenomenon: many who slash calories eventually regain weight, often overshooting their original size. Their metabolic rates dropped, leading them to feel constantly fatigued and ravenous.

It’s not in your head—adrenaline, cortisol, and other stress responses can amplify food cravings. Meanwhile, your resting metabolic rate can plunge, leaving you with little energy and a powerful urge to eat. It’s a protective mechanism: the body is programmed to avoid perceived starvation.

Understanding these natural defenses gives you a new outlook. Instead of blaming yourself for lack of willpower, you start to appreciate that your body is actually following ancient survival rules. The challenge is convincing it that there’s no famine to worry about.

What is Why We Eat (Too Much) about?

"Why We Eat (Too Much): The New Science of Appetite" by Dr. Andrew Jenkinson offers a revolutionary examination of how our bodies control weight, pivoted on recent advances in appetite and metabolism science. The book delves into the biological and hormonal dynamics governing our eating habits, explaining why the traditional "eat less, move more" approach consistently fails for many. By untangling the web of hormonal signals and environmental pressures, Jenkinson reveals why some people can't maintain weight loss and why modern diets often backfire.

The unique proposition of the book lies in its shift from viewing obesity as a lack of self-control to understanding it as a complex biological system defending itself against perceived starvation. The text elucidates how factors like stress and sleep can inadvertently fortify our body's "weight set-point," making weight loss an uphill battle. As Jenkinson unfolds this enlightening perspective, he provides readers with practical tools to work with their biology rather than against it, helping redefine the path to sustainable weight management.

Review of Why We Eat (Too Much)

Dr. Andrew Jenkinson's "Why We Eat (Too Much)" is a profound exploration of what truly drives our appetites and how biological factors shape our weight narratives. The book sets itself apart by providing an accessible yet deeply insightful look into how our hormones, like leptin and insulin, contribute to the weight gain saga. Recognizing that our bodies are wired to resist sudden weight changes, Jenkinson explains how our "set-point" functions in safeguarding our survival, even as we diet.

With a meticulous breakdown of experimental research and patient experiences, Jenkinson capacitates readers to confront their eating habits with a scientific lens. His narrative extends beyond into the impact of lifestyle factors like stress and sleep, which often entwine with metabolic functioning. What stands out is his ability to translate complex science into a conversational tone, making the text relatable and enlightening for a broad audience.

Jenkinson's robust recommendations highlight the importance of incremental changes rather than radical shifts. Readers can gain practical insights into resetting their set-point through nutritionally balanced diets and stress management. With theories supported by solid science and practical frameworks, this work stands poised to reshape our understanding of diet and weight control. It's a must-read for anyone wishing to comprehend their bodies better and towards achieving healthy weight management that honours one's biology.
