The only difference between this book and any other runners or non-runners magazine, book, pamphlet, or programme for weight loss is that it gives a specific ratio of carbohydrates to fats to protein appropriate for running (i.e., 50:25:25) and reminds you that, yes, vegetables are carbohydrates, not just pasta and potatoes.
Other than that, the the rest of the book reads like info and filler and stretching out what is a very useful but easy-to-impart bit of advice. If you have any other books on running, if you have ever been on any diet or eating plan, if you have ever glanced on the internet at a running site for their diet info -- this book will seem like a collasal waste of money.
If you know absolutely nothing about eating at all, and this is the first nutriion/diet/exercise book you have ever purchase, you will be pleased to be introduced to the basics.
All the rest of us, just remember that daily food intake ratio: eating in the vicinity of 50% carbs, 25% fat, 25% protein... and you don't need this book. There, I've saved you some dosh :) -- but of course other studies show that ratio to have about 10% more fat than most women runners need when they want to lose weight, but... now I'm just being picky...
