The book in overview viii Chapter 18 gives a brief introduction to the website that supports this book . Getting Started I wrote this book to be read in two halves . The first hundred pages , to the end of the chapter on exercise , are all you need to read to get started . Spend some time developing your new healthy eating lifestyle and then come back and read the second half of the book . This second half deals with managing the obesity-promoting world we live in , along with the deeper issues of the mind and how it can sabotage our success . Finally , you will realize as you read this book that I have to take you into deeper issues if I am going to help you to lose weight and / or keep off weight you have lost . Things are not what they seem in the world of weight loss . On the other hand , this fascinating , wondrous world offers us insights into not just how to manage our weight , but how to more successfully take on all sorts of personal challenges in our busy lives .
