  • Read all of our reviews of popular diets.


    I have to admit, I didn’t realize how long the Eat Right 4 Your Type diet has been around. Maybe it’s just that time flies but I was surprised to hear that it’s been over 10 years since this diet was introduced. Of course I also find it hard to believe that it’s been that long since I graduated college, so maybe it’s just me.

    Also known as the Blood Type Diet, this plan makes diet and exercise recommendations based on your blood type. It claims that following it’s recommendations will help you lose weight and reduce your risk of chronic diseases like heart disease and diabetes

    The suggested food items are based on when the blood type first appeared in history. The diet asserts that if you eat the wrong foods your health could suffer due to adverse chemical reactions between the foods you eat and your blood.

    Blood Type O
    According to the diet, this is the oldest blood type; it is also the most common. Type O blood emerged during a time when people were hunters and gathers and so people with this blood type should eat a lot of meat and avoid grains.

    People with Type O blood are encouraged to eat a diet low in carbohydrates and high in protein. Emphasis is placed on lean meats, poultry and fish while restricting grains, breads, beans and legumes. The diet also advises against dairy products. Lots of high-intensity aerobic activity is recommended for people with type O blood.

    Blood Type A
    The diet encourages people with type A blood to be vegetarians. The idea behind this recommendation is that type A blood emerged during a time when people were cultivators and ate from the land.

    Red meat is highly discouraged while lots of fish and vegetables are encouraged. Some dairy is also recommended. People with Type A blood should engage in light exercise like yoga, tai chi and moderate-intensity aerobic activities.

    Blood Type B
    Type B blood emerged when people were nomads and so they ate a wide variety of foods. The diet claims that people with this blood type have a tolerant digestive system and so their diet is the least restrictive.

    The diet recommends plenty of meat, dairy, fruits and vegetables with some fish. It discourages the consumption of chicken, bacon and lentils. You are encouraged to exercise moderately, combining moderate-intensity aerobic activities with relaxation activities.

    Blood Type AB
    Just as you would suspect, type AB is a combination of types A and B. People with this blood type should follow the recommendations of both diet plans. People with type AB blood should do more calming activities.

    The biggest difference between the suggested foods for type A and B is meat. The diet recommends that people with type AB eat meat but in smaller portions. Seafood, tofu, fruits, vegetables and dairy are encouraged.

    My Thoughts
    While reviewing this diet, I can’t help but think that it could be rather restrictive for someone whose food preferences don’t line up with its recommendations. So, I asked around to find out how my friends and family members would do if they had to follow this diet plan.

  • I guess I shouldn’t have been surprised to find the results pretty evenly split. Half the people I asked felt the diet recommendations fit their food preferences, while the other half did not. For the most part, those who felt the diet didn’t line up with their food preferences were the people with Type O blood who did not like the idea of limiting carbohydrates.

    I am a type A and the diet’s recommendation of a mostly vegetarian diet lines up pretty well with my food preferences, but my father is also type A and he never met a meat product he didn’t like. This leads to another concern, what do you do to accommodate family members with different blood types?

    While there is no research to support the theory behind this diet, there is nothing nutritionally unsound with it’s recommendations. I do feel it important to note that as with most diet plans, weight loss is likely due to restricting food intake rather than any interactions between your blood and food.

    My biggest concern with this diet remains the risk that it could be unnecessarily limiting for people whose food preferences don’t match the recommendations. I still feel that a well-balanced diet is the safest route to a healthy weight and that all foods, in moderation, fit into a healthy eating plan.


    * Grade: B. While overall the diet does not eliminate any food group, depending on your blood type it may not recommend all of them. The diet plan can also be unnecessarily limiting. This diet does include recommendations for physical activity, which is a vital component to weight loss and weight maintenance.
