Developed by Dr. Peter D’Adamo, ND, you basically eat or avoid eating foods according to your blood type, and this is supposed to help you lose weight. For example, this diet specifies that blood type B people should avoid corn, wheat, lentils, tomatoes, chicken, peanuts and sesame seeds, and they should eat goat, mutton, venison, eggs, green vegetables, and low fat dairy. However, the Mayo Clinic doesn’t think much of this diet and they say that “eating or avoiding certain foods according to your blood type isn’t thought to have any favorable influence on weight or health” and they also feel that this diet plan is unlikely to meet your nutritional needs at all. Again, another diet that leaves you malnourished in the end as well as very tired if you’re a B blood type person who has to go out and start hunting and shooting all of your food.
The blood type diet is a nutritional diet advocated by Peter D’Adamo, a naturopathic physician, and outlined in his book Eat Right 4 Your Type. D’Adamo claims that ABO blood type is the most important factor in determining a healthy diet, and he recommends distinct diets for each blood type.
Throughout his books D’Adamo cites the works of biochemists and glycobiologists who have researched blood groups, claiming or implying that their research supports this theory. Nevertheless, the consensus among dietitians, physicians, and scientists is that the theory is unsupported by scientific evidence.
D’Adamo’s Blood Type Diet has met with criticisms for many different reasons,some of which have been addressed publicly by D’Adamo.
