The blood type diet was made popular by the 1996 book "Eat Right for Your Type" by Peter J. D'Adamo. The theory of this diet revolves around protein lectins whose shape differs from food type to food type, and fitting a blood cell of a particular blood type only. But according to the Mayo Clinic---and practically every other medical authority---the evidence for this theory is nil, making it nothing more but another fad diet. Nevertheless, below are the foods supposedly associated with weight loss for each type.
Step 1
Eat seafood for weight loss if you are Type O, in addition to red meat, liver, kale, spinach, broccoli, salt and kelp. In other words, you thrive on protein. Avoid wheat, corn, cruciferous vegetables and beans.
Step 2
Eat a vegetarian diet if you are a Type A. Seafood, legumes, and fruits are all allowed, but for weight loss you should concentrate on soy foods, vegetables and pineapple. Use vegetable oil for cooking and dressings.
Step 3
Consume green vegetables if you are a Type B. Also eat eggs, low fat dairy and meats such as goat, lamb, venison, mutton and rabbit, according to D'Adamo's website. Do not eat chicken. You should also avoid corn, wheat, tomatoes, sesame seeds and peanuts as they might make you gain weight.
Step 4
Eat seafood if you are a Type AB, and also eat tofu, green vegetables and dairy---especially yogurt and kefir. Avoid caffeine and alcohol, particularly when under stress. Because you are a combination type, you have some of the reactions to foods of two other blood types. For example, lima beans, corn, buckwheat and sesame seeds are likely to provoke an insulin reaction, just like in Type B. Also, try food combining, such as avoiding starches and protein at the same meal. It will be easier on your stomach.
