A person who wants to lose weight can get confused with all the variety of diets and be unsure which one actually works. Almost all of us have heard about the blood type diet. It became trendy years ago and has sparked a lot of controversy. Some find it effective, others think it is totally useless.
What does it consist in?
The person who invented this type of diet is Peter D’Adamo, a naturopathic physician and author of the book Live Right 4 Your Type. He argues that the chemicals in the foods we consume react with our blood group and following the same diet does not work for everyone, precisely because of the different blood types.
The naturopathic physician believes that the way our ancestors ate brings us health benefits and helps for a better digestion. When a person follows the blood type diet, they are more effective in preventing disease, improving the function of their digestive system, and generally have more energy. This is due to the fact that each type has its own antigen that reacts negatively to some foods and causes illnesses.
Blood types did not occur at the same time in the course of human evolution because at different points on the planet, humans evolved at a different rate, they obtained their food in different ways and therefore had a different menu. Some hunted and ate mostly meat, others learned how to cultivate the land and how to raise animals.
Different blood types
How are blood types determined?
If you want to follow the diet, you need to know your exact blood type and consume the foods that are recommended for your blood type.
Blood type O
The ancestors of the people with Blood Type O were hunters and mainly ate meat, fish and animal products. They can metabolize cholesterol contained in animal products well. The menu in this group includes high-protein foods reducing fat, carbohydrates and sugars, including those contained in fruits and grains. Moderate consumption of whole milk products as well as beans and cereals are recommended.
Consumption of beef, veal, lamb, mutton, buffalo, venison and also minced meat and eggs is recommended. Ham, pork, goose meat and bacon are forbidden. Among fish, herring, mackerel and cod are beneficial, and smoked salmon, barracuda, octopus, black caviar, shrimps and crab are not allowed. Products such as butter, mozzarella, goat cheese, feta cheese, and soy products like soy milk and cheese are considered neutral.
While adhering to this diet, it is recommended to take dietary supplements, especially those that help digestion. Among fruits, oranges, tangerines, blueberries, strawberries, melon and avocados are not allowed. Prunes and figs can are allowed. Olive oil and linseed oil are allowed, but you should exclude corn and sunflower oil and peanut butter from your menu. Pumpkin seeds and walnuts are allowed among the nuts, and peanuts, cashews and Brazilian nuts are forbidden. Among legumes, peas and beans are beneficial. Lentils and black beans are forbidden. Sauces are not recommended, especially ketchup and mayonnaise.
Neutral foods for this type include barley, buckwheat, rye, millet and rice. Corn, bran, oats, wheat, gluten and all flour products are considered harmful. Spinach, broccoli, red peppers, parsnip and turnip are recommended among the green leafy vegetables. In return, you should not go for potatoes, mushrooms, black olives, corn, eggplants and all kinds of cabbage. Onions and garlic are also very beneficial.
Prohibited beverage are the coffee, black tea, strong spirits, and orange juice. Soda water and tea are beneficial. Beer, red and white dry wine are considered as neutral. Running, jogging and cycling are recommended among the sports.
Blood Type A
According to D’Adamo, people with this blood type absorb carbohydrates better, but it is difficult for them to break down animal proteins and fats. It is believed that their ancestors were cultivators and farmers. In people with this blood type, the diet does not include meat and dairy products, but emphasizes on vegetables and fruits, whole grains, beans and gluten-free whole grains.
Organic food is recommended due to the fact that, according to Peter D’Adamo, people with this blood group type have a weak immune system and sensitivity to pesticides. Olive oil, coconut oil and other vegetable oils from nuts and seeds are allowed. Caffeine should be avoided by emphasizing on a large quantity of water in herbal teas. Foods such as white flour, flax and rye should be avoided and supplements such as calcium, iron, vitamin A and E should be taken. Yoga, Tai Chi and walking are recommended.
Blood Type B
The ancestors of people with blood type B were nomads and crossed large areas of land which made their body tolerant to a rich variety of foods. The most appropriate blood type B diet is one which is balanced and includes different macronutrients. The diet for this blood type resembles the paleo diet and includes various meats, leafy vegetables and fruits (bananas, grapes, plums and pineapple). Appropriate are olive oil and linseed, cereal products such as oats, millet and rice.
People with this blood type should avoid peanuts, corn, lentils, buckwheat, sesame and tomatoes. It is best if chicken is replaced with other types of meat (turkey, lamb), eggs and low-fat dairy products if these do not cause indigestion. Recommended drinks are green tea, fresh fruit juice and water. Energizing sports such as running, cycling, jogging are recommended as physical activity.
Blood Type AB (Mixed)
For people with this type of blood group it is considered that their body can easily digest different foods that contain both proteins and fats. It is considered for this type to be the result of mixing of the blood types rather than of the evolution or the environment. For this reason, it combines the features of Type A and Type B.
The diet for type AB includes fish, meat, dairy products, grains and legumes, as well as a variety of vegetables and fruits, making it rich in fiber. It includes green leafy plants, peaches, cherries, plums, grapes, kiwi, lemons, pineapple. Excessive consumption of red meat, cereals, seeds that prevents digestion is not recommended. It is recommended to eat a variety of fish to compensate for the lack of meat. The recommended foods for this blood type are tofu, dairy products, seafood and leafy vegetables.
The naturopathic physician claims that people with a this blood type have low gastric acid and should avoid alcohol, caffeine beverages, smoked or canned meats. You can drink coffee, green tea and water. Alcohol, vinegar, corn and beans should be avoided. You can do both slow and relaxing as well as more intense sports.
Blood type and weight loss – what is the co-relation?
This diet also has its opponents and supporters, and there is a lot of debate about whether it is effective or not. Some specialists, such as medics and anthropologists, say the diet is completely useless. It has not yet been demonstrated that the division of blood into types is interrelated to the type of nutrition.
Although there are people who report good results, diet is not recommended for a longer period. If followed for a longer time, the diet can cause a deficiency of valuable nutrients in the body. The lack of dairy products reduces the intake of calcium, leading to osteoporosis, while the small quantity of meat deprives the body of iron and a number of valuable nutrients, leading to anemia.
If you still want to try out the diet and it’s your first time, it is not advisable to follow it for a long period, 1 week or less, or to use it for building a healthier diet. However, let’s not forget that keeping a temporary diet by itself can bring us positive results, but if we go back to our previous unhealthy lifestyle afterwards, we will lose the results. Only the inclusion of healthy habits in our daily lives, proper diet and regular physical activity can guarantee a beautiful figure.
