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.
