Blood type diet: what it is, how it works and what to eat


The blood type diet is a type of diet where you must consume foods according to each blood group (A, B, AB or O), combining the practice of specific physical exercises, in order to improve digestion and metabolism, helping with weight loss.

The creator of the diet, North American physician Dr. Peter d’Adamo, also states that the diet improves the immune system and reduces cholesterol and triglyceride levels in the blood, helping to prevent diseases such as heart attack, atherosclerosis or stroke.

However, the blood type diet has no scientific proof or consensus from the medical community. Therefore, the ideal is to consult a nutritionist to assess your general health status and outline an individualized eating plan.

How the diet works

According to Dr. Peter d’Adamo, each blood type has its characteristics, ancestors’ eating habits and, therefore, following a specific diet could improve digestion, health and reduce the risk of disease.

According to the theory of this diet, people with blood type A need to eat more vegetables, fruits and legumes. People with blood type B should prioritize milk and dairy products, those in group AB should follow a diet containing foods from group A and group B. People with blood type O need to consume more animal protein.

Dr. Peter d’Adamo argues that foods can be considered:

  • Beneficial, when they prevent and cure diseases;
  • Neutrals, when they cause, but also do not cure, diseases;
  • Harmful, when they can cause disease.

The ability of each food to cause or cure diseases varies according to each person’s blood type.

In addition to diet, it is also recommended to perform physical activity regularly, depending on the person’s blood type, which varies between light exercise, such as meditation, and more intense exercise, such as running.

Blood A Diet

People with type A blood should prioritize a diet rich in vegetables, fruits and legumes, as, according to Dr. Peter, these people have greater difficulty digesting animal proteins, requiring easily digestible foods. Milk and dairy products can be consumed, but in small quantities, as can eggs, and can be a source of complementary protein.

According to the creator of the diet, people with type A blood should also practice physical activity regularly, preferably outdoors and relaxing, such as yoga, meditation or walking, 3 to 4 times a week, lasting between 30 to 45 minutes.

Blood diet B

According to the blood type diet plan, people with blood type B should prioritize milk and dairy products to have more energy. Furthermore, these people are able to digest fats better in general.

In addition to diet, Dr. Peter d’Adamo also recommends, for people with blood type B, the practice of balanced physical exercise, of light intensity, such as meditation, and of high intensity, such as weight training, 2 to 3 times a week , lasting between 25 and 30 minutes.

AB Blood Diet

People with blood type AB need a balanced diet, according to Dr. Peter, and this group’s diet should be based on both the blood group A and group B diets.

According to Dr. Peter, people with blood type AB should also practice light exercise, such as hatha yoga or meditation, twice a week, and high-intensity exercise, such as running, cycling or CrossFit, three times a week, lasting 45 to 60 minutes.

O blood diet

Because they have an easier time digesting all types of meat and fat, blood group O diets should, according to the creator of the diet, be rich in proteins of animal origin. Furthermore, it is recommended to avoid the consumption of milk and dairy products, as they can cause weight gain, inflammation and tiredness.

In addition, people with blood group O need to practice aerobic exercise, such as running and cycling for 30 to 45 minutes, at least 4 times a week.

Does the blood type diet really work?

The blood type diet can help with weight loss and weight loss, as it is based on a healthy, balanced diet and associated with physical activity. However, There is no scientific proof that this type of diet improves digestion, energy levels or health.

Furthermore, this diet may not be very practical, as people with blood type O need to eat animal protein daily, which is impossible for a vegetarian person, for example.

Therefore, if you wish to go on a diet to lose weight or to help treat a health problem, it is advisable to consult a nutritionist to carry out a complete assessment and create a nutritional plan adapted to your individual needs.
