Losing Weight With The Blood Group Diet: How Useful is The Method?

Myth or truth: Certain eating habits are said to be due to blood type. Conversely, the blood group diet should make it easier to lose weight. However, today’s critics advise against this diet.

What blood groups are there?

The first blood transfusions were carried out as early as the 17th century, but without the knowledge of the possible incompatibility of donor and recipient blood.

Thanks to the Austrian doctor Karl Landsteiner, the so-called AB0 system was implemented. A, B, 0 and AB stand for a specific surface structure of the red blood cells. This is genetically determined and thus inheritable. It is important to note that each person can only have one blood group.

Blood group A: contains antigens type A (antibodies against type B)
Blood group B: contains type B antigens (antibodies against type A)
Blood group AB: contains antigens type A and type B (no antibodies)
Blood group 0: no antigens (antibodies against type A and type B)
Accordingly, not just any random person can donate blood to all blood groups. Blood group 0 is the most compatible and can donate to all blood groups. Blood group A can only donate to type A or type B. Blood group B can only also donate to type B or type AB. And lastly, blood group AB, which can only donate to type AB. The blood group distribution in Germany is 43 percent blood group A, 41 percent blood group 0, 11 percent blood group B and blood group AB is the least common at 5 percent.

What does blood type say about your eating habits?

The author Peter J. D’Adamo already attracted a lot of attention in 1996 with his book “4 Blood Types”*. The basic message: Everyone should adjust their food according to their blood group. He describes blood group 0 as the dominant hunter-cavern type that needs meat. Blood group AB, on the other hand, are gentle vegetarians, and for blood group B, everything else belongs on the table besides dairy products.

blood group 0

Blood group A was created in the Neolithic period. These people would have a tolerant immune system but a rather sensitive gastrointestinal tract. That is why a vegetarian diet with lots of fruit and vegetables is very beneficial for this type A. This type can also eat small portions of fish several times a week.

blood group B

Which diet should suit which blood group?

Unlike strict diets, a blood type diet doesn’t require you to count calories. In addition, the blood type diet for all four types relies heavily on fruits and vegetables, but very little on fiber and other necessary nutrients. Furthermore, according to D’Adamo, the so-called lectins play an important role in the blood group diet or the corresponding specific form of nutrition. These are

Blood group 0 (meat eaters) should avoid whole wheat products because of the gluten. With the exception of butter and farmer’s cheese, all cow’s milk products are rather indigestible and thus make the metabolism and weight loss more difficult. According to D’Adamo, legumes are not an important part of their diet because they tend to cause digestive problems because of the lectins, which are said to lead to blood clotting. People with blood group A (vegetarians

People with blood group B (omnivores) would only have to limit themselves to poultry, wheat and rye products. Almost all types of vegetables and fruits are well tolerated by this blood group, although they would only tolerate a few legumes. A lot of cheese, milk and meat would also be well tolerated. For people with blood group AB (The Enigmatic

Criticism of the blood group diet

As plausible as all this may sound, there are still a few points to criticize about the diet:
D’Adamo is wrong: The blood types did not develop one after the other, but in parallel.
No scientific study has yet proven that lectins can lead to blood clotting, which makes them intolerable. By cooking legumes, for example, they are easily neutralized, which means that everyone can digest them easily.
The diet is partly very low in fiber and based too much on animal proteins, which is not environmentally friendly or sustainable. Too much meat can also lead to inflammation, gout or urinary stones.
Giving up certain foods is not healthy. The DGE also advises against it and recommends a balanced diet with all the necessary nutrients.
CONCLUSION: The blood group diet is therefore strongly discouraged. Still, this knowledge can serve as background information as to why some foods taste better to you or are easier to digest than others. Follow your instinct and eat what you feel like in a balanced way. Because your gut feeling usually knows quite intuitively what is good for you and what is not. count on it.

The Blood Group Horoscope: What is Behind It

In Japan, the so-called blood group horoscope is widespread.

The history of the horoscope

The discovery of the AB0 blood group system in 1901 laid the foundation for all blood group research. The discoverer was Karl Landsteiner. The Japanese doctor Hara Kimata continued to work with this system. In 1916 he published a text in which he postulated a connection between blood type and character traits.

His theory was well received: At the end of the 1920s, the psychologist Takeji Furukawa took up the doctor’s theses and continued to research them. However, his research fell into oblivion – until the beginning of the 70’s. Journalist Masahiko Nomi came across the research results and published the basis of today’s horoscope with the article “Detecting compatibility by blood group”.

That says the blood group horoscope

The blood group according to the horoscope should give the following conclusions about the character:
According to the blood group horoscope, with blood group A you are considered to be particularly honest, patient, careful and responsible. Other positive character traits such as consideration, politeness, prudence and diligence are attributed to you. On the other hand, there are also some negative characteristics such as tension, narrow-mindedness and a very conservative attitude to life. Blood group A is very common in Germany.
If you have blood group B, you should be a very active personality. You are seen as a creative doer, very open-minded, passionate and positive. But here too there are negative character traits such as recklessness, egoism, unpredictability and reckless action.
According to the Japanese blood group interpretation, people with blood group 0 should be very goal-oriented, optimistic and solution-oriented. This gives them good leadership qualities, among other things. In Japan, people with blood type A are considered “romantics” and thus “ideal partners”. Negative character traits are said to include jealousy and vanity.
Blood group AB is said to indicate a high level of sensitivity. In addition, these people are also said to have a high level of unconventionality, spirituality and creativity. People with the rare blood group are said to be very strenuous, unpredictable and sometimes narcissistic.
By the way: If you don’t know your blood group yet, you can find out in a number of ways. Another way to do something good is to donate blood. As a rule, you will find various contact points near where you live where you can donate blood and where you can then find out your blood group using the blood donor card. Alternatively, you can either get a quick test to take at home from the pharmacy or ask your family doctor to do a blood group test.

Blood Group Diet: It Really is That Useful

The blood type diet is based on the assumption that people can tolerate different foods depending on their blood type. The idea sounds interesting – but is there any scientific evidence that the blood type diet works?

In the 1990s, the American naturopath Peter J. D’Adamo invented the blood type diet. It is based on the assumption that our blood group is decisive for which foods we tolerate better and which less well. How can this work?

The four blood groups 0, A, B and AB differ in that different antigens are found on the red blood cells. According to D’Adamo, certain proteins from food, the lectins, couple to different antigens, causing the blood to “clump”. This increases the risk of many diseases. So the blood type diet means that you avoid foods whose lectins bind to the antigens in your blood. This should make you healthier and slimmer.

Blood group diet: which foods for which blood group?

According to the blood type diet, you tolerate the foods best that your ancestors ate when the blood type was created. This results in this list according to the blood group diet:
Blood type 0: According to D’Adamo, this blood type originated in the Stone Age when people lived as hunters and gatherers. Accordingly, you should eat a lot of red meat and fish, as well as a lot of fruit and vegetables. On the other hand, you should avoid cereals, legumes and dairy products. This diet is similar to a high-protein, low-carb Paleo diet.
Blood type A: This blood type is said to have emerged when people settled down and began to grow crops and other crops. That means you eat vegan for the most part, fish is also allowed every now and then.
Blood group B: Blood group B is said to have originated with the nomadic peoples of Asia. Accordingly, meat, dairy products, fruit and vegetables are on your menu.
Blood group AB: Your diet corresponds to a balanced mixed diet.
The classifications according to D’Adamo are in some cases much more precise, for example one blood group allows one type of fish and another allows that type of fish.

Does the blood group diet work? The state of research

There is scientific evidence that suggests a concept like the blood type diet might make sense:
A 2012 study came to the conclusion that the risk of developing certain diseases depends on blood type.
Nine years earlier, a review found that the way your body absorbs and processes nutrients is linked to your genes.
Is this evidence that the blood type diet works? No – neither publication shows that there is a connection between your diet and your health based on your blood type.

In fact, there is no evidence that the blood type diet works. In a systematic review study in 2013, scientists from the Belgian Red Cross looked for sources that prove that the diet works. You haven’t found a single meaningful study. Your review also prompted the German Society for Nutrition (DGE) to write in a press release that the blood group diet lacks any scientific basis. The University of Toronto even published a study in 2014 concluding that there is no connection between your health and your diet that depends on your blood type.

According to the current state of research, his theory of how the blood groups came about is also wrong. In 2012, scientists analyzed the genomes of several primate species and concluded that blood types have existed for millions of years.

Blood Type Diet: Interesting, but not recommended

You can probably lose weight if you follow the blood group diet: depending on your blood group, the selection of foods you can eat is very limited. This means that you will find it difficult to integrate the blood type diet into everyday life and you will probably eat an unbalanced diet. Therefore, experts advise against using the blood group diet, regardless of the scientific situation. If you eat a balanced diet and mainly eat seasonal vegetables and fruit, you will get all the nutrients your body needs.
