I bought this book 18 months ago, together with a couple of other low fat cookery books. It has been my favourite, by a long way and I can't hesitate to recommend it.
The book is divided into 2 sections - the first provides educational info regarding fat, health etc. I'm not bad on this sort of thing normally, but I did find that this section contained information I wasn't aware of, and refreshed my memory on other key points.
The second section is the recipes themselves. All I have cooked have been extremely flavoursome. They are a bit different to the norm (if I see another fishcake recipe I shall SCREAM!) and for a moderately experienced cook, easy to cook on a week-night. The ingredients don't have to cost the earth (some tasty veggie recipes which by default less expensive than meat) although there are also some nice 'special occasion' ideas.
Each recipe includes total fat, sat fat and calorie content data (plus others. Even better are recommendations for reducing fat further within some recipes (such as leaving the skin off chicken breasts).
The proof of the pudding, however, is in the eating! So, I'm pleased to say that following a low fat (rather than a low calorie) diet, I have lost 1 1/2 stone and reduced from a size 14 to a size 8/10. It took a few months - but this is probably more healthy than a quick crash weight loss plan. Moreover, I have fundamentally changed the way I buy, cook and choose food (mainly as a result of this book and its ideas) which means that keeping the weight off is easy. The only warning I would give is that it has cost a lot of money to buy new clothes!
