If you've ever wondered why the latest fad diet doesn't work for you... well, there are lots of reasons, mostly the fact that it's a fad diet. But it could also be that you're the wrong blood type for the kinds of foods the diet recommends. Peter D'Adamo makes a persuasive argument that your blood type is an evolutionary marker that tells you which foods you'll process best, and which will be useless calories. He covers the entire range for each of the four blood types, from entrees to condiments and seasonings, and also makes type-specific exercise and lifestyle recommendations.
