Could eating a diet based on your blood type -- O, A, B, or AB -- help you trim down and get healthier? That's the idea behind the Blood Type Diet, created by naturopath Peter J. D'Adamo. D'Adamo claims that the foods you eat react chemically with your blood type. If you follow a diet designed for your blood type, your body will digest food more efficiently. You'll lose weight, have more energy, and help prevent disease.Find out what you should be eating, and how you should be exercising in accord with your own type.

 

For instance,

 

For Type O: Focus on higher protein, eliminate grains, and perform energetic aerobic exercise
 

For Type A: Go vegetarian, exercise more mildly, and ease tension through meditation 
 

For Type B: Vary your diet with a diversity of food groups, and exercise moderately
 

For Type AB: You have most of the benefits and intolerances of Types A and B

 

Many bodybuilders do suggest this book and swear by its outcome. Its  good way of dieting and feeling much better on simply changing the way you eat a little.  Although as good as it may be just remember sometimes your blood type does not match your taste buds....lol
