Are you looking for a new way to approach your keto diet? Have you heard about the popular idea of determining your keto diet based on your blood type? It’s a concept that has been gaining traction for a good reason. This blog post will explain how to use your blood type to determine your keto diet and why it might be an effective way to approach your diet.

How Blood Type Affects Keto

Blood type affects keto because blood type can determine how your body processes and uses the nutrition you consume. Different blood types have different levels of enzymes, which can affect how your body digests and absorbs the nutrients from food. Depending on the type of enzymes your body produces, it can affect your ability to burn fat and produce energy.

Type A

Type A individuals should focus on eating a diet mostly made up of plant-based foods, such as fruits, vegetables, legumes, nuts, seeds, and grains. These foods should be low-carb, high-fiber, and rich in protein. Dairy, eggs, fish, and poultry should be included, but the amount of dairy and other animal-based products should be minimized. This diet has been linked to reducing the risk of diabetes and other blood-sugar-related issues.

Type AB

Dr. D’Adamo, a natural-health expert and researcher, claims ABs can consume various keto-friendly foods, such as proteins, dairy, extra carbohydrates, and some plants that may be incompatible with other blood types. 

He says tomatoes, for example, are not suitable for A’s and B’s, but ABs are fine to eat them. Instead of chicken and beef, ABs should choose turkey and lamb. Additionally, processed meats, avocados, radishes, and cassava-based items are not advisable for ABs. It is suggested that ABs maintain a daily carb intake of under sixty grams to ensure the best results.

Type B

B’s ancestors followed a diet high in protein and healthy fats, with lower amounts of carbohydrates. This would include eating many meat, dairy, fish, eggs, healthy fats, vegetables with low starch content, fruits like berries, nuts, and seeds. It is recommended to keep your daily carb intake at around 40 grams for the best results.

If you typically eat dairy-rich foods, consider speaking to your doctor about taking a daily magnesium supplement of 300 to 500 milligrams. Magnesium is known to fight tiredness and is essential for a type B metabolism. Your calcium intake may impact your magnesium levels, so it’s worth discussing with your doctor.

Type O 

O’s have been able to digest high-fat, meat-based meals with the help of the digestive enzymes and stomach acid they have. To help keep their diet balanced, they can also include fish, eggs, greens, berries, and nuts. For the best results, they should aim to get high-quality protein, such as grass-fed meat, and keep their carb intake to 40 grams daily.


Blood type significantly affects how the body responds to a ketogenic diet. It is important to note that there is no one-size-fits-all approach to the ketogenic diet. People with different blood types may have different reactions and responses to the diet and may require different amounts of carbohydrates and proteins to reach optimal health. Ultimately, it is important to listen to your body when it comes to a keto diet, regardless of your blood type. Pay attention to how your body reacts to different foods and adjust your diet accordingly.
