Among the many diet plans for weight loss, the blood type diet stands out. It assumes that the preferred eating behavior is individual and depends on the biochemical processes in the blood. That is, a suitable set of products for the owners of the first group can harm people from the third group, and vice versa.
The diet was developed by American nutritionists, D'Adamo's father and son. They developed a theory about the evolutionary influence of human lifestyle on biochemical processes in the body, as a result of which different blood groups were formed.
General principles
D'Adamo's nutritionists have developed four detailed menu plans - one for each blood type. The father, James D'Adamo, started the research and the son, Peter D'Adamo, finished it. The result is a well-thought-out theory, the main thesis of which is that the main difference between people lies in their blood type. The essence of these differences is in a different relationship to lecithins, cellular substances found in all tissues in the body. It is a building material and foundation that comes with food and differs depending on the type of food.
In 2014, Canadian scientists conducted large-scale studies that showed the diet's ineffectiveness.
The nutritional principles developed by D'Adamo are based on the selection of exactly the lecithins that the body needs depending on the blood group. Medicine and science are skeptical of this technology, but it is not losing its popularity. In which the authors presented their research and recommendations, Eat Right 4 Your Type has been at the top of the bestseller lists for 20 years since it was first published in 1997. Patients with weight problems contact the D'Adamo Clinic. Here they are subjected to complex treatment - diet combined with the intake of vitamins, relaxing procedures and psychological training. The blood type diet attracts celebrities, models, actresses and TV presenters who leave rave reviews.
The main role of a weight loss diet is to continue feeding from what distant ancestors did. Hunters should eat more meat, farmers - vegetables. The menu is well thought out in detail, recommended, undesirable and prohibited foods are indicated.
First blood group
The owners of the first blood group include 33% of people. According to D'Adamo and his predecessors, they are the descendants of hunters, leaders and hunters. It is essential that your diet includes:
- Meat, preferably red, preferably beef and lamb;
- Offal: liver and kidneys;
- oily sea fish: salmon, sardines, halibut;
- River fish: sturgeon, pike, perch;
- Seafood: clams, oysters;
- from vegetables, berries and fruits - broccoli, lettuce, figs, plums.
From time to time, add seaweed, sprouted grains, and olive oil to the menu. The main rule is to provide the body with a sufficient amount of protein and trace elements that will help assimilate it. As a drink, you should choose tea with mint and rose hip broth.
First blood group "hunters" are prone to rapid weight gain due to slow metabolism, which is exacerbated by abuse of non-recommended foods. D'Adamo classifies gluten products as such, especially baked goods, milk, cottage cheese, yogurt, kefir. The presence of corn, beans, lentils and cauliflower on the menu has a negative impact.
People in this group should avoid excessive amounts of salt and apple juice. In general, the authors of the diet believe that "hunters" are characterized by good digestion and good health. At the same time, however, they have to stick to a conservative line in their eating habits and be careful when trying new things. Vigorous exercise is the key to health and wellbeing in this category.
Second blood group
The people of this group are the descendants of collectors and farmers. Their diet is radically different - meat is strongly discouraged and all vegetables and fruits should be available in large quantities. "Zemplepaschtsy" on the earth about 38% - this is the most numerous group.
The following products are recommended that have a positive effect:
- most vegetables (exceptions are listed below);
- Cereals and cereals;
- all vegetable oils;
- Fruits, in particular figs, lemons, plums, grapefruit;
- Fish and seafood to replace meat - cod, trout, sardines and mackerel.
Women and men with the second blood group gain weight and lose health from any meat. As a last resort, you can allow a piece of white - but in no case red is allowed. Dairy products and foods high in gluten are negatively affected. It is necessary to reduce the consumption of beans, eggplants, potatoes, mushrooms and tomatoes. Bananas, coconuts, tangerines, papaya, melons are not recommended from fruits. Do not drink black tea and orange juice, carbonated drinks.
If they follow the right nutritional principles, "farmers" are not at risk of digestive problems or obesity. But, according to D'Adamo, misusing meat will lead to heart attacks and cancer.
Third blood group
According to D'Adamo's definition, 20% of the planet's inhabitants who are lucky enough to be born with the third blood group are omnivores. This group appeared later than the first and second during the migration and knows how to adapt to the situation. The ancient "nomads" ate whatever was available and as a result of evolution developed a resistance to the harmful effects of any food.
The menu for this group is varied and rich in different products. Must be included:
- Meat and fish as sources of protein; fatty sea fish also contains a large amount of valuable fatty acids;
- Eggs;
- Dairy products;
- Cereals and cereals;
- Vegetables and fruits.
Buckwheat and groats are not recommended, made from vegetables - corn and tomatoes, melons and watermelons. The negative effects are caused by eating fatty pork, chicken, seafood, and olives. Alcohol is harmful to health.
In general, the system assumes that "nomads" are prone to autoimmune diseases. It is easy for them to lose weight, and following nutritional principles is good for health and metabolism.
Fourth blood group
The youngest and rarest blood group, 10% of people belong to it. As part of the diet, its owners are called "riddles" or "cities". D'Adamo has developed an unexpected and original diet for her that will help her lose weight and stay healthy.
The biochemistry of this group emerged only a millennium ago and is the result of an evolutionary process.
The doctor recommends:
- Soy and tofu;
- Fish and caviar;
- Milk;
- Vegetables, fruits, berries;
- Rice;
- dry red wine.
All of these products have various beneficial effects on the body: they improve blood circulation, accelerate metabolism, strengthen the nervous system, etc.
It is necessary to remove red meat and offal from the menu. A large amount of protein and iron negatively affects the health of "city dwellers". From vegetables and grains, corn, buckwheat, wheat, oranges, bananas, guavas, coconuts are not recommended.
The main problem in this category is predisposition to diseases of the nervous system. They are also at high risk of cancer, heart attacks, and gastrointestinal problems. People in this group are prone to colds and have weak immune systems, so it is necessary to monitor adequate vitamin intake. Diet and moderate physical activity protect against disease.
