Scientists have reported the ineffectiveness of a popular diet
Last reviewed: 01.07.2025
Summer is a period of time when many people are seriously concerned about their appearance: women read articles about healthy eating, men buy gym memberships, in general, almost everyone is interested in some aspects of a healthy lifestyle. One of the things that women are interested in is, of course, various diets and nutrition systems.
Experts from Belgium reported that recent studies have proven the absolute ineffectiveness of the once fashionable blood type diet. European nutritionists believe that this diet is not only useless, but even dangerous for the body, so they advise against the advice given by the author.
The author of the popular diet, Peter D'Adamo, insists that the nutrition system he developed is not a diet in the everyday sense of the word. He calls for a permanent change in lifestyle and eating style and claims that a week's change in diet will not produce miracles.
An American doctor developed a nutrition system in which each person's diet should depend on their blood type. The author gave each of the four groups its own name and justified this by the fact that different blood types did not appear simultaneously, but at different periods of time. The basis of the blood type diet is that a person, in the author's opinion, should consume different foods depending on their blood type. The author believes that the foods that were available at the time of the appearance of, for example, the second blood type, will be useful for a person with the second group, but dangerous for those with the third. This statement, based on imaginary naturalness, has won over many people who have begun to consciously refuse vegetables, meat and other products that are good for the body. The second point that cannot but please is that food consumption does not need to be limited, the restriction only applies to food products.
The author of the diet claims that different foods, depending on a person’s blood type, are perceived differently by his body and digestive system and are absorbed by the body differently.
Belgian specialists became interested in the principles of the new-fangled diet after nutritionists noticed that the number of patients talking about the new diet system had increased significantly. After doctors decided to study the fashionable diet system in more detail, it turned out that, despite its popularity, not a single authoritative scientific study of the diet had been found to date. All opinions about the effectiveness of the diet system were formed by ordinary people who did not consider the diet from a scientific point of view. The only scientific study that examined the effect of nutrition on people with different blood types concerned a low-fat diet and only indirectly touched on the topic, which described the reaction of people with different blood types.
Nutritionists claim that the blood type diet cannot be considered effective and even consider it quite useless. Experts are sure that only healthy eating and active physical exercise can contribute to weight loss.
