Blood Type O
Type Os thrive on intense physical exercise and animal protein. Unlike the other blood types, Type Os muscle tissue should be slightly on the acid side. Type Os can efficiently digest and metabolize meat because they tend to have high stomach-acid content. The success of the Type O Diet depends on the use of lean, chemical-free meats, poultry, and fish. Type Os don't find dairy products and grains quite as user friendly as do most of the other blood types.
The initial weight loss on the Type O Diet is by restricting consumption of grains, breads, legumes, and beans. The leading factor in weight gain for Type Os is the gluten found in wheat germ and whole wheat products, which interferes with insulin efficiency and slow down metabolic rate. Another factor that contribute to weight gain is certain beans and legumes (lentils and kidney beans) contain lectins that deposit in the muscle tissues making them less "charged" for physical activity. The third factor in Type O weight gain is that Type Os have a tendency to have low levels of thyroid hormone or unstable thyroid functions, which also cause metabolic problems. Therefore it is good to avoid food that inhibits thyroid hormone (cabbage, brussels sprouts, cauliflower, mustard green) but increase hormone production (kelp, seafood, iodized salt).
Several classes of vegetables can cause big problems for Type Os, such as the Brassica family (cabbage, cauliflower, etc.) can inhibit the thyroid function. Eat more vegetables that are high in Vitamin K, which helps the clotting factor which is weak in Type Os. The nightshade vegetables can cause lectin deposit in the tissue surrounding the joints.
Because of the high acidity stomach, Type Os should eat fruits of alkaline nature such as berries and plums.
Type Os should severely restrict the use of dairy products. Their system is not designed for the proper metabolism. If you are a Type O of African ancestry, you should eliminate dairy foods and eggs altogether.
Blood Type A
Type As flourish on vegetarian diets. Type As are predisposed to heart disease, cancer, and diabetes. It is particularly important for sensitive Type As to get their foods in as natural a state as possible: fresh, pure, and organic. When you get on the Type A Diet, you will naturally be thinner. If you are accustomed to eating meat, you'll lose weight rather rapidly in the beginning as you eliminate the toxic foods from your diet. And when you follow the Type diet, you can supercharge your immune system and potentially short-circuit the development of life-threatening diseases.
When Type As eat meat, they experience sluggishness. Type As have low stomach-acid content, therefore they have a hard time digesting meat. Since Type As eat very little animal protein, nuts and seeds supply an important protein component. Type As also thrive on the vegetable proteins found in beans and legumes, except those mentioned for the "Avoid" list. These beans can cause a decrease in insulin production, which may cause obesity and diabetes. Tofu should be a staple in the Type A Diet.
Dairy foods are also poorly digested by Type As, and can cause metabolic slowdown. Type As can tolerate small amounts of fermented dairy products such as yogurt, kefir, nonfat sour cream, and cultured dairy products.
Vegetables are vital to the Type A Diet, providing minerals, enzymes and antioxidants. Type A are very sensitive to the lectins in potatoes, sweet potatoes, yams, cabbage, tomatoes and peppers. They aggravate the delicate stomach of Type A. Type A should eat more fruits that are alkaline, avoid mangoes, papaya and oranges for they are not good for your digestive tract
Blood Type B
The sturdy and alert Type Bs are usually able to resist many of the most severe diseases common to modern life, such as heart disease and cancer. In fact, a Type B who carefully follows the recommended diet can often bypass severe disease and live a long and healthy life. Type Bs are more prone to immune-system disorders such as multiple sclerosis, lupus, and chronic fatigue syndrome
The Type B Diet is balance and wholesome, including a wide variety of foods.
For Type Bs, the biggest factors in weight gain are corn, buckwheat, lentils, peanuts and sesame seeds. These foods have different lectin that affect the efficiency of the metabolic process, resulting in fatigue, fluid retention, and hypoglycemia. The gluten lectin in wheat germ and whole wheat products also adds to the problems cause by other metabolism-slowing foods.
It is important to leave off chicken for Type Bs. Chicken contains a Blood Type B agglutinating lectin in its muscle tissue, which attack the bloodstream and potentially lead to strokes and immune disorders. Type Bs thrive on deep-ocean fish, but should avoid all shellfish. The shellfish contain lectins that are disruptive to the Type B system.
Type B is the only blood type that can fully enjoy a variety of dairy foods. Most nuts and seeds (especially peanuts, sesame seeds and sunflower seeds) are not advised for Type Bs., they contain lectins that interfere with Type B insulin production.
Wheat is not tolerated well by most Type Bs. They contain a lectin that reuce insulin efficiency and failure to stimulate fat "burning". Rye contains a lectin that settles in the vascular system, causing blood disorders and potentially strokes. Corn and buckwheat are major factors in Type B weight gain, they contribute to a sluggish metabolism, insulin irregularity, fluid retention, and fatigue.
Eliminate tomatoes completely from Type B diet. It has lectins that irritate the stomach lining. Fruits and vegetables are generally well tolerated and should be taken generously.
Blood Type AB
Multiple antigens make Type ABs sometimes A-like with weak stomach acid, and sometimes B-like with genetically programmed for the consumption of meats. Type AB do best when their muscle tissues are slightly alkaline. Type ABs can't metabolize meat efficiently because of low stomach acid, so it is important to watch the portion size and frequency. Chicken has lectin that irritates the blood and digestive tracts of Type ABs also. Tofu is a good protein supplements for Type ABs. Nuts, seeds, beans and legumes present a mixed picture for Type ABs. Eat nuts and seeds in small amounts and with caution.
Type ABs can tolerate dairy foods fairly well. But watch out for excessive mucus production.
Generally Type ABs do well on grains, even wheat, but keep in mind that the inner kernel of the wheat grain is highly acid forming in the muscle for Type ABs. Type AB benefits from a diet rich in rice rather than pasta.
Type ABs has a weaker immune system, so you will benefit from the vegetables, which are high in phytocheicals and the more alkaline fruits, which can help to balance the grains that are acid forming in the muscle tissues. Tomatoes do not impose any ill effects on Type ABs.
Type AB should begin each day by drinking a glass of warm water with the freshly squeezed juice of half a lemon to cleanse the system of mucus accumulated while sleeping
