By Dr. Sayantan Banerjee

The Obesity Exit Strategy

What If Losing Weight Was Never Simply About Willpower?
Why hunger, metabolism and weight regain work against you, and how to work with your biology instead.

About this book

What if losing weight was never simply about willpower? What if your biology has been working against you?

If you have tried diet after diet, battled constant hunger and cravings, lost weight only to regain it, or feel your body no longer responds the way it used to, you are not imagining it. After weight loss, hunger hormones rise, fullness hormones fall, and the body burns less energy than expected. Studies show these changes can last at least a year.

The Obesity Exit Strategy explains what is happening inside your body and how to work with it, not against it.

Who this book is for

  • Adults who have lost weight and regained it, often more than once

  • People using, starting or stopping GLP-1 medicines such as semaglutide or tirzepatide

  • Anyone who wants to understand the biology of appetite, insulin and metabolism

  • People with prediabetes, type 2 diabetes or fatty liver for whom weight is part of the picture

What you'll learn

  • Why obesity is a multi-hormone condition, not a willpower problem

  • How food structure, intermittent fasting, exercise, sleep and stress affect weight regulation

  • How insulin and appetite signalling interact

  • How to support your body's natural GLP-1 pathways through diet and habits

  • Where medication fits, and how to plan for the long term
