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

For the majority of people, the prescribed diet is low-carbohydrate, high in proteins (such as meat and fish), and low in dairy products. Type O should also engage in lots of exercise.

Foods for Type O?
Choose:  Lean beef, chicken, fish, turkey, vegetables, and fruit.

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?

Choose:lamb, venison, rabbit, fish, most dairy, rice, oatmeal, green leafy vegetables, most fruits.

Limit: beef, turkey

Some specific foods to avoid: chicken, other poultry, pork, shellfish, American cheese, blue cheese, sesame, lentils, chic peas, black beans, wheat, corn, tomatoes, avocado, pumpkin, olives, coconut, pomegranates, pepper, ketchup, distilled liquor

Blood Type AB

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

Foods for Type AB?

Choose:Lamb, mutton, turkey, fish, eggs, yogurt, non-fat milk, soft cheeses, most nuts and beans, most grains, most fruits and vegetables.

Limit: No grey area with type AB

Some specific foods to avoid: beef, pork, poultry, venison, shellfish, aged cheeses, sesame, kidney, black, and lima beans, sunflower seeds,  buckwheat, corn, avocado, bell peppers, black olives, tropical fruits, oranges, pepper, black tea, distilled liquor.

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

    I would never do this diet in my life!!!!!!!!!!!!!!!!!!!!!!

  • suzan moeketsi

  • 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.

  • Tyler

    I am going to use this for my health project

  • marissa zapanta

    Im type AB and its working diet plan for me,,,i hope i can get more diet program so i can continue and meantime my body shape with out worried to getting im my desire weight but still healthy.

  • crystal

    I love the blood type diet. LOST 60 lbs and have kept it off for 2 years now

  • emma

    i hate it…i nearly died!

  • Christine

    I switched to Blood type eating…I am a B blood type I had been eating chicken and tomatoes most of my adult life….I started eating lamb instead of chicken cut out the tomatoes….I lost 4 to 5 pounds within 2 weeks…my cholesterol dropped from 180 to about 160….I no longer count calories….I find when follow the blood type diet I feel satiated and don’t over eat.

  • Janet

    Just started the type o diet on advice by a first time seen naturopath. Willing to give it a try but a little skeptical. Any words of wisdom are welcome.

    • Darleen

      I only weigh 110 lbs, but have a poochy tummy due to menopause. I’m following this diet to feel good and help with preventing health problems prone to type O’s in the future. Also, my 22 year old daughter has been labled a “medical mystery” because we can’t find a cause for her many medical issues. We both started eating for our blood type (she’s type A) just three days ago, she feels some improvement and I can’t believe my tummy is hardly poochy! I’m not a big “write a review” person, but when something works, it works!

  • Engr. Igegbe Emmanuel U.

    I like blood type and diet. I have tried taking diets appropriate to my blood type and now enjoy better health than before.

  • Barb N

    I love this book!!! I lost 15lbs in 30 days several years ago. I also discovered that the skin condition I was diagnosed with was nothing more than food allergies. After 90 days of eating a typa A diet I no longer had any skin issues. Now I know which foods where the problem and avoid them constantly and here it is years later my skin feels great. This is definitely a lifestyle change rather than a diet. I read this book because a friend lost 100 lbs following the O type diet. This not meant to be a weight loss program but a health regimen that can create weight loss if there is room for it. Health is the focus. It works!!!! It makes sense. Highly recommended read.

  • Kim

    I was tested for food allergies and many of the foods I reacted to are listed as foods not good for my blood type. I have been gradually eliminating foods from my diet and replacing them with recommended ones for over a year now. I continue to feel much better and recognize it is difficult to do over night and a life long change.

  • Yolanda

    No doubt your blood type is either “A” or “AB”, the cancers seem to ravage these groups most. Don’t delay change your eating habits now! Do your own research. This is not a diet it’s a lifestyle change. We’ve been conditioned for so long to eat what our parents put on our plates! Save your life first.

  • tom

    I have been on this diet for 8 years. I really never had a problem with weight. I am a blood type O. I figured out years ago that certain foods did not settle in my system.I had stomach cramps, lethargic and sometimes felt ill. After reading bloody type O diet. I can say that book changed my life. Several foods were giving me issues. Foods that I always suspected now had proof. Corn always upset my stomach. Also, started with ezekiel bread that bread digests very well in my system. Stopped eating all white and wheat bread. My weight dropped a few pounds and I got leaner. Probably the biggest was I stopped drinking orange juice. I switched to pineapple juice WOW no more stomach acid or cramps. Today I am 48 years old I weigh in a very lean 175. I can easily run 5k races and train 3 -4 times a week in the gym. I firmly believe that this diet is worth checking out. I don’t consider this a diet but, rather a way of life. I get to eat all the food I enjoy anyways and stay healthy and strong. Can beat this diet !

    • Jen S

      I started on the “Type O” diet and I have lost 12lbs since this pass June, but I have dropped from 1X to large, this is a huge deal for me… I no longer need the Stomach meds that I have been on for about 15 + years! Being a diabetic and Type O makes it more challenging to find the right foods to eat. I was diagnosed with diabetes type II in 2003 I have lost 50lbs ( gained 25lb back in between) I had a head injury, little over a year after that a stroke, and then Cardiomyopathy from a virus. Decided to go to rehab and college. Anybody can do it, just have to put your mind to it! I am glad I didn’t get rid of my smaller clothes ?:o)
      Good luck everybody.
