I'd heard good things about this book and thought it sounded like a novel but useful tool to aid healthy eating. The idea of giving clear alternatives to calorie laden snacks is very clever. The book is beautifully photographed and very easy to understand. There are, however, two problems with it. The first is not of the authors making: This is an American book and a lot of the alternatives suggested are not available in the UK ie light waffles, bialys (a sort of bread roll), vegetable pepperoni. The second problem is that the book is a little inconsistant. One page shows eight potatoes with salsa as having 880 calories while a few pages later an individual baked potato with salsa is quoted as having 150 calories. They can't both be right. Other inconsistancies include bagels containing approx 400 calories (although this to varies in the book) whereas the ones in my local supermarket all contain about 240 calories - is this down to overestimating the calories or are the bagels more fattening in the US? It would be nice to know. These things made me lose confidence in the book. Also, some of the measurements are exact while other items are just described as weightless portions. I still think the idea of the book is good and it looks great but I think the inconsistencies would need to be ironed out before I could trust it.
