Blood Type Diet

 By Mizpah Matus B.Hlth.Sc(Hons)

A blood type diet is a nutrition plan based around your blood type.

This kind of diet became popular with the release of Peter D’Adamo’s book Eat Right 4 Your Type.

blood type dietThe book continues to be a bestseller. D’Adamo claims that the diet will not only bring about weight loss — but can assist with allergy and infection resistance, and will achieve overall good health.

Dr. D’Adamo started out as promoting the eating of the right foods as a way to improve health and wellbeing. However, in the last several years  he has developed a whole line of nutritional supplements consisting of pills, shakes, bars, skin products, and even chocolates developed nutritionally for each of the four blood types.

This diet has many followers and detractors. Some question the science behind the diet and find it overly complex to follow and understand.

What is a Blood Type Diet?

In a nutshell this diet revolves around eating foods that D’Adamo believes work chemically with a dieter’s particular blood type. He believes that by eating foods your “body was designed to eat” it can heal itself and become healthy.

Blood Type O

Limit: dairy, grains, legumes, and beans.

Some specific foods to avoid: avocado, brazil nuts, oranges, cauliflower, mustard greens, cabbage, brussels sprouts, pork, goose, poppy seeds, eggplant, corn, melons, coconut, coffee, beer, black tea, ketchup, vinegar, milk, yogurt.

Blood Type B

People with type B should eat plenty of certain meats, dairy, some fish, and plenty of fruit and vegetables.

Foods for Type B?

Blood Type AB

This plan combines some aspects of both the A and B diets and has the most acceptable food choices for dieters.

Is This Diet For Real?

The author claims that much of the recommendations are based on scientific evidence – but perhaps it is too early to make this claim.

The following are some reasons to be cynical of his blood type theory:

  • Metabolism and/or sugar/insulin sensitivity are probably key factors in deciding diet – not blood type.
  • Two people can have very different metabolisms and have the same blood type. One could be sensitive to carbohydrates or sugar, whilst the other needs a high carbohydrate diet.
  • Weight loss and other health improvements may occur on this diet – not so much because of blood type combinations, but because of a healthier diet! The author encourages people to cut down on processed and refined foods. Good advice for anyone regardless of blood type.
  • The book also includes low calorie diets that will probably bring about weight loss in anyone (once again, regardless of blood type).

Eat Right 4 Your Type Banned Foods

Any diet containing a long list of banned foods can be difficult to follow.

Eat Right 4 Your Type and the various blood type diets included encourage a predominantly meat and fish diet, while grains, potatoes, cereals, breads, pasta are not encouraged. Interestingly, certain vegetables and fruits are also banned.


Eat Right for Your Blood Type does promote exercise as way to increase health and vitality as well as for stress relief. Each blood type has exercises that are recommended as suitable for their bodies as well as recommendations for intensity and duration.


  • Many have reported better health from eating according to their blood type.
  • Dr. D’Adamo has years of experience as a naturopathic doctor.
  • Weight loss can also occur.
  • Promotes the use of whole foods.


  • Dr. D’Adamo isn’t a medical doctor.
  • Supplements are promoted heavily.
  • Many healthy and nutritious foods are banned for certain types.
  • Eating out can be difficult.
  • Many people are healthy eating all foods despite their blood type.

Improved Health Isn’t Likely Due to Specific Foods

Many have reported dramatic results after they have begun eating according to their blood type. However, this could largely be attributed to the fact people are giving up refined and processed foods, which is recommended for all types.

Originally Dr. D’Adamo’s Blood Type Diet started out as predominantly whole food nutrion based, but seems like since has evolved into a front to sell all kinds of nutritional supplements and miracle concoctions to users of  the blood type diet plan. The supplements are expensive and most likely unnecessary.

    Everyone in my family is ‘O’. I had a friend help my overweight daughter get on this diet and within one year she lost nearly 100 pounds. Yes, she was that overweight. She did have some physical activity as recommended. We tried different things and none of them helped. I believe having a healthy diet with exercise is key. Yet, one person’s diet plan won’t necessarily work the same for another. Now because of my daughter’s weight loss, she looks better, feels better and is more physically active since she was in middle school. I have made gradual changes in what I prepare for my family and it’s proven to work. When we eat a proper breakfast, we feel fuller longer and our energy levels don’t fluctuate anymore. Thanks!!

  • Alvita

    I have been on the Blood Type Diet for little over 2 years I feel great I started it because I was having food problems and the pills my Dr prescribe bothered my stomach, my niece told me of this diet and I have never looked back through Dr. D’Adamo’s allergy book I learned that wheat and gluten bothered my Asthma after I gave up the wheat my asthma got better I have lost 65 lbs. yes it’s very restrictive but I feel so much better.

  • Alissa

  • Topsy

    I am a blood type B and just recently started with the Diet. Its too early to tell if the diet is working or not.

    • nora

      hi Topsy

      i just read this diet today …. any updates in how you are feeling i’m thinking of doing it as i’ve turned 40 and finding that i need to looking into changing my diet

  • doho2008

    I call complete BS on this diet, I’m type O and it told me to avoid beer and then in the “Sample meal” it says beer is OK for dinner?! Yeah, I think this guy is a hack

  • Ward T.

    I am type AB and have been following my recommended food list for several years. I feel better than ever with no acid reflux or heartburn and tonnes more energy. Wish everyone would get this important information for their health!

  • Amanda

    I am type A and have lost 12 lbs since I started this diet. I have noticed that since I followed certain directions, such as avoiding red meat, that I have a lot more energy, sleep better, and just feel better mentally and emotionally. I went from being a size 20 to a size 16. The people who swear by this diet are right, it is not just a diet, it is a lifestyle change and it is hard. I still deviate from the lists, which is probably why my results to date are less stellar than everyone else’s. Recently, I ate 2 mandarin oranges a day for a few days and I ended up sick as a dog for 3 days until my body finally purged itself of the oranges (oranges are on my Avoid list). I cut out dairy completely and I really noticed a difference in that I wasn’t bloaty or tired all the time. I believe this lifestyle works. My hopes are that I will be a size 14 by Easter and a size 12 by the summer (I haven’t been a size 14 since before my daughter was born in 2007 and I haven’t been a size 12 since I was in high school (10 years)).

  • Amie

    I am a vegetarian by choice and am blood type o
    making me a meat eater. Red meat literally makes my stomach turn
    Can I stay vegetarian and adapt a blood type diet? I’m also addicted to lentils and beans which I’ve just discovered I can’t have. Any advice?

    • bee

      Amie, if u feel good as a veg, why change? Im type O and tried this diet…it made me really sick and flared up UC and FMS…my body does not do well with meats

      I suggest reading up on Dr Fuhrman and his books. I think u will find the answer there

  • Zinna

    I have the book at home. My mother-in-law’s infact. I haven’t tried the diet as yet due to scepticism bt after hearing people’s stories and reading on how the diet has changed people’s lives, you better believe I’m on it soon as I get back from my weekend getaway.

  • mariana

    what is ostrich, is it game or chicken? please can you tell me?

    • Kate

      Hi, it’s game. It’s a red meat and incredibly healthy for you, obviously depending on your blood type, according to this diet. It has almost no fat in it. It’s also REALLY tasty…

    • ted

      Neither. Ostrich is a bird so it would be classified as poultry like chicken is.
