Weight-Loss Diet for People with Blood Type O


type O diet 2 The author of a popular diet book “Eat Right for Your Type”, Dr. Peter J. D’Adamo, states that healthy weight can be achieved by eating in accordance with our blood type. People gain weight because they eat wrong foods - the foods, which can be harmful for their blood type genetics. Our ancient ancestors were lean and energetic, since their bodies were designed to efficiently consume and expend fuel they needed for the peak performance.

As the blood type diet is tailored to the cellular composition of our bodies that carry the ancient blood type genes, specific foods will cause either weight gain or weight loss depending on our blood type.

People with blood type O carry the most ancient blood genes of all of us. They are direct descendants of Palaeolithic hunters and gatherers, whose digestive tract still functions the most efficiently when their diet is close to that of the cavemen. Type Os are best described by the following:
- meat eaters;
- possess hardy digestive tract;
- are intolerant to dietary adaptation;
- need intense physical activity to stay lean and alert;
- are prone to sluggish metabolism and weight gain if eat wrong foods.

In other words, people with blood type O require daily physical exercise and a diet based on natural animal products with an addition of fruits and vegetables. Their Palaeolithic ancestors ate high-protein, high-fat diets with very few carbohydrates, and their bodies were able to efficiently metabolise such fuel into energy and high performance. But if a person with blood type O consumes a diet high in carbohydrates and poor in fats and protein, he will inevitably gain weight.

More specifically, if a type O wants to lose fatty tissues, the basic approach is to restrict or even eliminate the consumption of grains, breads, legumes, and beans, because the leading factor in weight gain for type Os if the gluten found in wheat and other whole grains. The gluten lectins inhibit the type 0s’ insulin metabolism, thus interfering with the efficient use of calories for energy. The consumption of beans are legumes are another weight-gain factor, because the lectins contained in these products tend to disrupt type O’s acid/alkaline balance and slow down their metabolism. One more weight-contributing factor is a low level of type O’s thyroid hormone function. The symptoms of underactive thyroid include weight gain, edema, fatigue, and muscle loss.

To sum up, if people with blood type O want to lose excess pounds, they should avoid the following foods:
- whole wheat, rye, and oatmeal products (all of which contain harmful gluten);
- corn (slows metabolism);
- lentils, kidney and navy beans (impair calorie utilization);
- cabbage, cauliflower, Brussels sprouts, and mustard greens (inhibit thyroid production).

type O diet 1 Foods that encourage weight loss in type Os:
- red meats and liver (aid efficient metabolism);
- kelp, seafood, and iodized salt (increase thyroid production);
- broccoli, kale, and spinach (boost metabolism).

Sample weight-loss menu for people with blood type O:

Breakfast: 2 scrambled eggs, 1 slice of gluten-free bread with almond butter, 1 orange, and a cup of herbal tea.

Lunch: Chicken salad with garden greens, 2 plums, and a glass of seltzer water.

Snack: Rice cakes with natural maple syrup, 1 banana, and a cup of green tea.

Dinner: Lamb stew, steamed broccoli, string bean salad, and a cup of rice milk.

    O’s should avoid oranges, per D’Adamo’s book, “Blood Type O: Food, Beverage and Supplement Lists.”

    Yet, you include “1 orange” in your breakfast menu for Type O’s. NOT GOOD–even careless.

    I agree. O’s shouldn’t eat oranges. Great question!!

    Since Dr. D’Adamo really does not insist on following his blood type-based dietary recommendations to the letter, there is no harm is eating an occasional orange even for people with blood type O! :) His reason for not recommending oranges for people with blood type O is because of their high degree of acidity, not because of really dangerous lectins, like in grains or milk, which should always be avoided.

    However, a healthy individual with this blood type won’t really damage his or her heath by eating a fruit from his “avoid” list. Much more harm would be induced by consuming wheat or dairy products.

    1) I thought that ‘rye’ was at least neutral….I eat ‘Rye Krisps’ all the time.

    2) What do Blood-Type Os do if they abhor lamb, for instance?

    3) Why drink rice milk when soy milk has more protein?

    I just read the “Sample weight-loss menu for people with blood type O” at the end, and I was amazed, I am a blood type O and those are exactly my favourite food.. Exactly! Eggs, chicken, lamb, broccoli, tea..!

    Should I say it is a coincidence, or is it really true?

    I suffer from diabetics and high blood pressure. I have recently having boils and rashes all over my body especially around my breast andtarmpit including my back. I have seen my Doctor and have taken more than two dose of antibiotics yet my situations the same. I have been referred to cancer clinic and am waiting for their appointment. I am following the Blood type diet for the past three weeks. I am worried and wonders if I am missing out some foods in my diet.
    Please advise.

    Cecilia - the boils in your armpits may be hydradenitis suppurativa. This condition is best treated by a dermatologist. You may have to try an elimination type diet to see what is causing this skin condition. One week, no dairy, next week, no wheat, etc… Process of elimination should hopefully determine the culprit. Good luck!

    Does anyone know if coconut flour is OK for Blood group o people

    I totally disagree. I was a straight-edge vegetarian for three years, and a vegan for nearly two years, and have bared witnessed to a decrease in metabolism, energy and overall health, now that I’ve started to introduce lean meats into my diet (a direct result of living with a spouse and kids), I lack the energy I once had on a vegan/vegetarian diet. If you are a vegetarian or a vegan, protein must be attained through the consumption of whole grains and legumes.

    Sorry, but I think this book/dieting theory is BS.
