This is a hard work to get in to from the point of view of 'having a go' at losing weight. That said this book is actually about controlling your weight and reversing the tendency to gain weigh, especially as we get older.
You really need to read this book twice.
FIRST - to get into all the areas that it covers, including the roles of insulin, good fats, vitamins, minerals etc and how they all work together to control weight.
SECOND TIME - to do the surveys (there are a lot of them) and thus find out which of the plans you need to follow to control insulin, appetite, replace missing vitamins and minerals, and sort out cravings.
This is a well researched diagnostic book with lots of meal ideas too.
WHATS WRONG with this book is that ALL the vitamin and mineral supliments, as well as the insulin balancing product are sourced from its support website - look in Holland & Barratt or other health food stores and get the suppliments from there - they seem to work out a lot cheaper!!!!
Still, I have read the book TWICE - done the surveys and worked out my insulin resistance (medium) - and will start with the plans soon - just need to buy the vitamins now.
