Blood Type Diet

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.

The 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. He also has supplements designed to combat various conditions and disorders as well as home tests to use to assess  blood type, free radical count, and genotype.

What is a Blood Type Diet?



Most of the population has blood type O. Here the prescribed diet is low-carbohydrate, high in proteins (such as meat and fish), and low in dairy products. The author suggests specific foods to avoid; such as avocados, brazil nuts, and oranges. Type O should also engage in lots of exercise.

Blood Type A should avoid red meat, eat plenty of fish and vegetables, with a low dairy intake. Light exercise only.

Blood Type B should avoid chicken and bacon, eat plenty of meat and dairy, some fish, and plenty of fruit and vegetables.

Blood Type AB combines the A and B diets.

Is This Diet For Real?

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

Exercise

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.

Pros

  • 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.

Cons

  • 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.

Conclusions

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.

  • I’m type o and I’ve been on the diet since last Jan. and have lost over 60 lbs. and feel great! Yes, it’s a struggle, and yes, I had to give up some of my favorite foods, but, they were also making me sick. They were making me cough, when I ate anything with dairy, wheat, white flour, I would start coughing until I was blue in my face, then my allergic reccomended I try this diet along with a Health food store and I went along with it, mind you I started this diet cold turkey, I stopped everything all at once, which probably wasn’t very smart, but I thought why not, in 1 month I lost 20 lbs. just from dairy alone. But you really have to read everything in the stores what contains dairy if it says whey, it contains dairy. As far as bread I eat Rice Pecan (Love It), I get it at HEB in the freezer section by the garlic bread as for the crackers I eat Rice Pecan or Rice Almond, you can get them at Health food store. I drink Almond milk, instead of soy milk, and I plan to lose 20 more pounds slowly. I walk everyday sometimes 2 or 3 miles, this has been the best new lifestyle I’ve found yet. I’ve tried Weight Watchers, Curves, it just didn’t work, this has!!! But get the book, it has great recipes too.

  • I am Type O..
    I have forever been trying to force myself into a strict vegan lifestyle because I simply dislike meat/fish and prefer the vegetarian diet. It seems like everything I was trying to do is incorrect, so I am going to give this diet a shot and see what happens.

  • Just heard about this way of eating today. Sounds difficult but it seems to totally make sense. God gave us what we need … we decided over time what we want instead of what our bodies actually need. Weight Watcher’s has always worked for me but I still was uncomfortable with all of the processed foods. They are convenient and yes, I lost the weight … but I really don’t believe that my choices were as “healthy” as they could have been. I believe that this is reading more about. Thanks for all of the comments, pro and con … it’s food for thought … now I will give some thought on the foods that I put into my body!

  • i have just found out i am blood O after donating last month. i have been eating mostly vegetarian foods with chicken, ostrich and fish. i hate red meat with all my life and i dont think i will be able to chew it with my own teeth, let alone swallow it. i will stick to ostrich meat, which i know is high in protein. the research is so true, i love bran, wheat etc but i feel uneasy after eating it, my tummy gets so hard that its even a mission to breath. now i know why. i love avocados, how do u suggest i stop eating them? man this research can be confusing at times

  • Being a young adult, I’ve found this to be extremely difficult, especially being in my first year of college. Three years ago I began giving up some of the things that were “harmful” to my body (i.e. mostly the red meat and the dairy part) but have yet to transition into the vegetables and fruits. I’ve discovered that by giving up the things that were “harmful” I now can’t even digest them without feeling sick, especially pork. That convinces me to stay away from it. When I began, I wasn’t overweight, but I dropped the diet two years ago and gained some weight. When I got back to what I was originally doing, I lost the unnecessary weight I gained. Now I’m not overweight anymore, so I haven’t lost weight for several months, but my body fat level continues to drop and I can see I’ve developed some extra muscle. In the next year I’m hoping to complete my transition so that I’m eating more than I am now…since it would be healthier. It’s a slow process for me…but in the last year I’ve gone from a size 6 to a size 3(ish), but still weigh the same. It’s quite amazing actually.

  • I am type B…
    I lost no weight on the diet but I feel better…I am lactose intolerant but I didn’t find it to be a conflict. My skin is so much healthier and my energy has leveled …no more ups and downs. I recommend trying the diet or at least parts of it and see if it works.

  • My sister had told me about this way of eating some time ago. She gave me a list of the foods recommended for each blood type. The list was broken down by meats, vegetables, fruits, grains, nuts and oils. It also noted whether the item was highly beneficial, neutral or to avoid it completely for your blood type. About 3 months ago my psoriasis became severely inflamed so I decided to see if what I was eating was on the list as an avoid item. I had been eating a salad with balsamic vinegar every day and noticed right after eating the salad my skin would itch. There it was in black and white “avoid all vinegars” I am type O. Right after that I went to my homeopathic doctor and told him my findings. He told me to follow a gluten free diet. While I was there I asked him to test me for a yeast infection in my body. I felt that since my favorite foods had been pizza and pasta that that could be a possibility. The test came back positive for yeast in my intestinal track, twice the normal amount. For the last 3 months I have been taking a low dose statin for the yeast infection and have been following the food requirements for the O blood type. Previously I was alway fatigued and what I thought was arthritis I have come to believe was inflammation from eating the wrong food. I feel much better and I have been losing weight although I don’t know why. I still eat pretty good I just stick to the list. I mention the yeast infection to give other people with type O blood the heads up if they too eat alot of wheat foods. Get it checked. You’ll have alot more energy when it’s fixed. By the way I’m 61 and you don’t have to be tired just because your 61. Hope this helps someone.

  • I was told about this diet about 9 years ago. My personal trainer at the time got me to test my blood. I found out that I’m type A. He gave me my list of foods to eat/avoid, and I was floored. All the foods on my avoid list were foods that, growing up, I HATED. My parents used to have to fight me tooth and nail just to get me to swallow a small piece of meat. If it were up to me, I would have eaten fish every day. Cheese and eggs (especially mixed together) would give me migrains, and so would beef broth. I then knew this diet was “for real”. I didn’t end up sticking with the diet then, because I was only 18 years old, and weighed like 100lbs if that, so needless to say, I didn’t feel like I needed to follow a diet. Now, after two kids, I care more about my health and started the diet. I feel SOOO good. In only 3 days, I lost 3 lbs, and my goal is to lose 10 more. I’m still learning the diet, so I’m slowly converting, but by the end of this year, I want to be completely on it. I’ve already stopped drinking milk, which is what I feel is the biggest challenge, but I’ve come to find that soy milk really isn’t that bad at all. Next will be cutting red meat completely (and I really love steak, so this will be a bit hard, but worth it in the long run).

  • ok so i was reading the “Blood Type Diet” and saw where it says that “most of the population has type O, thats so not true, i have type 0 negative and according to Science only 8 percent of the United Stated has type 0 blood type. and it says that type A should stay away from red meats, also not true my Fiance PFC Andrulat, US Army, has type A Pos blood type and when he got a liver infection the doctor on base told him he needed to eat MORE red meat because of his blood type so i give on this site sorry bye

  • This eating for your blood type stuff is bull. What about all of the scientific and nutritional proof that a vegetarian diet is the optimal diet for a long healthy life. SATURATED FAT is predominantly found in MEAT, DAIRY, and EGGS. There are countries where vegetarianism is the way of life, and they are FAR more healthy than the average American. The only reason this fad diet works is because it is telling people to stop eating cheeseburgers and frenchfries… well, duh!

  • I’m a type AB and I love this diet. I feel so much better. I love starchy foods (potatos, pasta,corn etc) but since I’ve stopped eating them , the inflamation in my hip joints seems to gone. I’m almost 50 and I’ve tried a lot of diets and this one is the best. It doesn’t hurt to try.

    by TINA BOSTON on 2/7/09
  • My friend suggested this diet to me because so far she has lost 60 lbs and still continuing to lose and she swears by this diet and thought I’d look it up for myself I will be buying the book that she has and will try it for myself because I need to lose additional 40 lbs myself because exercise alone doesn’t seem to be working me even when I’m watching what I eat so this diet DOES WORK! to all those who say it doesn’t – MAYBE YOUR CHEATING thats why it isn’t working for you or maybe your not getting your exercise that is recommended? because it is proven that it does work I seen it for myself!

  • I changed my lifestyle almost 10 years ago after reading Dr. D’Adamo’s early book “Eat Right 4 Your Type.” It has since progressed to “Live Right 4 Your Type” (LR4YT), and has undergone some changes from its earlier incarnations but is more-or-less the same diet. I didn’t lose miraculous amounts of weight or suddenly find myself with tons of energy at the time because I was still young and my body hadn’t been polluted with all the crap your average American east on a routine basis. For a few years in college I allowed the dietary portions of this diet to slip and began eating a lot more dairy (let it be known I am a type O), wheat, processed sugars, and other ‘food’. After graduating I resumed the blood type diet based on the writings contained in LR4YT. Mucus production slowed, my body decreased its intake of overall food, and I felt like I hadn’t in a long time. Currently my lifestyle allows for me to follow Dr. D’Adamo’s suggestions and I believe it to be better for doing so. Things others may be interested about are: the diet promotes heavy consumption of vegetables no matter your blood type (humans are NOT carnivores), the diet does not completely restrict you from eating those foods you so dearly enjoy (I will still eat avoid foods, but sparingly), and it I believe the diet also suggests a varied diet of moderation. There are so many diets people follow and there is not one that works for everyone. I think people should listen to their bodies and eat healthy and lead active lives (read- eat food not processed repeatedly for maximum shelf life, and go out and move your body). For those interested in another great book, look into “Brain Rules” by John Medina who has some great insight into why people need to do more than sit on our asses and drink soda pop… :P

  • Considering trying this diet – I am a blood type A. This will be difficult, because I won’t put my husband and kids on it (my husband is blood type O, needs meat!).

    Any advice from type A’s on the diet? Tell the truth, was it very hard? I can resist meat as long as I can have a little chicken once in a while, which is apparently ok (right?) will have a tough time giving up potatoes!

    by Ann on 2/25/09
  • I bought the book Eat Right for your Type, I would like to follow the diet. I have some few challenges though, Im a type B and living in Pretoria South Africa, the food which is outlined in the book sound very foreign to me. Is it possible to maybe get a suggested diet plan that include food commonly sold in South Africa? Please help I really want to start the diet.

    by Gugu on 3/10/09
  • I am a type ‘O’ and I actually did follow this diet. Although I do not eat any type of meat, I simply did not ingest the ‘avoid’ foods. My skin glowed, my intestinal distress vanished, and my face swelling disappeared. I did not realize how much edema I had until I didn’t have it anymore! Now, I just avoid wheat, and this ALWAYS cures my gut problems! But I may go back on the ERT plan soon. I LOVE the effects on my health!

    by Amnesiantoinette on 3/17/09
  • Hi…on top the blood type thing, i heard abt some doctors who would go further and test specific things in ur blood, and tell u exactly what to eat and what to avoid…
    anyone heard abt this?

    by sabine on 3/18/09
  • Hi -
    Have been on the Blood Type Diet for years now and have gotten my RA undercontrol with diet and supplements! I never did the extra test and it did not seem to make a difference to me. I mainly just started making choices based on the list and eventually my body was “clean” and the avoid list items started bothering my stomach or arthritis.

    by Jennifer on 3/19/09
  • I do believe there is some truth to this “eat right 4 your blood type” Diet. I have stared and I can feel a difference.

  • For SABINE
    I believe the “blood screening” you are referring to is a very thorough screening for full-blown food allergies as well as food sensitivities. The average cost of this screening is about $1,000 for the lab work and the cost of a Dr visit. As far as I know you will need to look for a naturopathic Dr who understands more about food allergies than the average MD.
    We had this testing done for my little brother. He has been a lifelong athlete, works out about 3-5 hours a day, 5-7 days a week. I have two other brothers who have this same athletic schedule. They are both tall and very lean and muscular. However, the third brother, the one we had testing done on, is short and chunky! Obviously their body types are very different and what they’re putting into their bodies affect them very differently.

    No matter which way you look at it, it seems like with that kind of a rigorous level of physical activity, ANYONE would be lean and fit, right? But what we’ve found is that that is just not the case. How is it possible that brother #3 remains chunky, in spite of all that activity? Granted all 3 of them eat crappy food, lots of soda and junk food, pizza, top ramens, etc. They eat good and healthy dinners, but basically, everything else they eat all day every day is a series of junk food. The fact that brother #3 remains slightly overweight and chunky in spite of his activity level leads me to think that he would be obese if not for his athletic training.

    Why is it that two people can eat the same thing and one person gets fat and the other stays the same? It seems not fair, and its not. But its a fact of life. People are different. Even in same family with same set of parents, siblings physical makeup and metabolism can vary greatly. So my sisters and I thought a lot about this problem, and the fact that brother’s #2 and #3 would constantly tease #3 and call him fat, etc. We knew brother #3 felt bad that he was chunky and is old enough that now he’s worried about whether girls will like him if he’s chunky. So, concerned about his self-esteem, we decided to take him to a naturopath and request the screening.

    We already knew of this possibility because one of my sisters had a very high risk pregnancy and delivered a beautiful baby girl. However, although seemingly healthy, my niece was constantly sick. Always sniffly, always had runny nose. Ran fever a lot, and constant diahrrea and almost always had what we though were diaper rashes, but no treatments prescribed from a Dr worked. They were not staff infections, or yeast infections, or even just skin irritations. After a process of elimination, we took her to a naturopath who suggested we have her tested for food allergies. This was a revelation to us. We had never even considered the possibility. In my mind, food allergy meant your throat closed up and you swelled up until you couldnt breathe. I had never considered the possibility that a reaction to food could manifest itself in a variety of ways. We were advised that there was an cheaper (couple hundered dollars) electromagnetic testing that could be done, in which she held a wand (we tucked it in her wasteband as she was very small) attached to a machine that read her bodie’s reaction to different food extracts and different combinations of certain foods. We were also advised of the blood test, although it was pretty much out of our budget at the time. We opted for the electromagnetic test. We had amazing results.

    We found out that the baby was allergic to wheat, dairy, cane sugar and sensitive to corn, and citris or acidic fruits including tomatoes. My sister was breastfeeding the baby, and the Dr advised that she would either need to stop eating those foods herself or stop breastfeeding the baby, as most of what the baby was getting was being passed through her breast milk. After the difficult pregnancy, my sister realized that she may never be able to carry another baby to term, and did not know if she’d have another chance. She decided she would rather radically change her diet and lifestyle and continue to breastfeed the baby. Miraculously, all my niece’s symptoms stopped completely, and my sister, who had been overweight all her life, dropped 100lbs over the next year! WITHOUT EVEN TRYING!! She did not even eat super healthy. But she DID stop eating highly refined foods, because in order to avoid cane sugar and corn syrup and wheat, you have no choice but to go the healthier route for whole grains and different types of grains that are not wheat. These are generally not available at the average grocery store. She had to buy rice and spelt pasta as well as spelt breads at whole foods. Its been about 5 years and she has kept the weight off. She works out periodically and tries to eat as healthy as possible, but has found an acceptable balance between eating healthy and still enjoying eating, such as soy yougurts and ice creams! After consulting further with their new naturopathic Dr, we realized that although she had never been tested, my sister obviously shared some of the same allergies her daughter had, which did not manifest themselves as rashes and runny noses, but instead as lifelong weight gain. The Dr. advised that she did not go back to eating those foods. Interestingly she could have been eating very healthy, like whole wheat bread and fruits and veggies and STILL have gained the weight. Because HER body is sensitive to them. So its important to find out what your body is reacting to.

    That experience is what led us to pursue the blood screening for our little brother #3 a few years later. He wound up with a long list of allergies and sensitivities. With help from us, he changed his diet and immediately, within 2 weeks had dropped 15 lbs. It is amazing actually. His blood screening results came with a small booklet with all the details of his particular results and information about food sensitivies and food allergies in general. Basically, in a natural environment, our bodies are designed to exist symbiotically with our earth. We are not supposed to eat the same thing all the time. If we were living off the land, we would not be eating highly refined foods and too much salt and sugar, and we would have a natural variety in our diet, based on what local foods grow at different seasons throughout the year. It is very common these days, for people to develop food sensitivities over time, by eating too much of one food. Even if its a relatively healthy food, our bodies dont do well with too much of anything at one time. We need to introduce variety into our diet, which can be very difficult to do! But I honestly believe it is key to being healthy. If you eat a variety of healthy food, you will not need to exercise for weight loss, or severely restrict your calories or diet, but for the pure pleasure of being healthy and physically active.

  • Although, my blood type is B, I’ve tried the A meals as well. The tofu cheesecake, tofu omelet and tofu lasagna are delicious. I’ve lost more than 100 pounds. This DIET WORKS!!! I’m skinny again, when I’m at the club, the men just come swarming.

    by Ms.Chen on 4/30/09
  • Yes, I had that blood test that tell you exactly what to eat. Those folks are not there anymore. Any idea where they do the test now?

  • WOW!! I heard this from my sister Geraldine Chen, so i decided to try it out. I was 190 lbs and I am now 101 lbs! I only did this for 3 weeks. This blood type diet is very effective! Although i absolutely HATE the food. I don’t know why my sister would like it. The tofu omelete tastes like my grandma’s feet. And the tofu cheesecake melted and now it tastes like im drinking from the toilet. I’ve noticed some negative side effects too. Geraldine has been addicted to these food and keeps on wanting to eat it with me. Sometimes, she would go to extreme measures to make sure she would have the bigger portion.

  • Give me a break…losing 89 lbs in 3 weeks? What, did you have some body parts amputated?

    by Ms. Chen Doubter on 6/23/09
  • First, get the library book and learn what it is about as it pertains to YOUR blood type. I am A. I learned I might be able to reduce the pain in my body by avoiding a few foods known to aggrivate pain for As. I decided to give it a try and be honest to see if it works. After only 3 weeks I noticed a very significant difference in the pain I was living with due to an arthritic hip and knee. I was able to keep up the plan and live a pain free live now. For As the plan most closely resembles the medditerranean diet so that is how I eat now. The items I had to give up that were most difficult were tomatoes, potatoes, peppers, bananas, oranges and all red meat and most dairy. I’m pain free and enjoying life.

  • I don’t understand how anyone can come up with this BLOOD TYPE food theory. For the longest time since creation, this was not an issue. Don’t tell me that you discovered something that no human soul has discovered. I assure you that GOD knew what HE was doing when HE created the fruits, vegetables, meat, nuts, beans, legumes, herbs, etc., for mankind. It was made for everyone and not for blood types only. Remember Atkinson’s Diet, to me its just another fad. Don’t play god, you are not. We have a lot of tropical fruits in my country, and you have not mentioned anything about them except a general statement.
