This book is fairly simple to abridge, as follows:
Chapter 1: Why aren't you thin yet? A bit harsh, but good news for Paul, as otherwise this book wouldn't have been a "number 1 bestseller". There are a few reasons why're you're not yet thin, apparently.
Pattern 1: Obsessive dieting: the more you diet, the more you fail. The more you fail, the less likely you are to succeed (or something like that). There is a *small* possibility that I am guilty of this...
Pattern 2: Emotional eating: Feel sad, eat to feel better. Feel shit about yourself because you ate too much, eat to feel better, repeat until they come and fetch you out of the window with a fire engine.
Pattern 3: Faulty programming: It's not your fault, your wiring is just a bit haywire. Luckily Paul can fix this. Read on...
Chapter 2: "The Simplest Weight-Loss System in the World". Apparently, this is trademarked. Is that even possible? Paul says that there are no naturally thin people - a point that I fundamentally disagree with. People might not stay naturally thin forever (sorry if you're reading this in your twenties, but your thirties and/or your childbearing years may not be kind to you), but some people are, just, naturally thin. I've seen Lily Cole, up close and in the flesh. She may look like a strange, beautiful, unusual alien creature, but I'm convinced that she is, at least, naturally, thin.
I'm ignoring the flaws in his logic and plowing on.
