I get questions sometimes from readers about the Eat Right for Your Blood Type diet plan. Published in 1996, Eat Right 4 Your Blood Type suggests that your blood type dictates your diet based upon ancestral styles of eating.
Basics of the Blood Type Diet
The basic reasoning is this: people with the same blood type share a common genetic heritage, while those with different blood types do not. Therefore, according to the author’s reasoning, people with Type O blood have different nutritional and exercise requirements than those who are Type As, and they are also susceptible to different diseases and health issues.
For example, according to the plan, people with blood Type O have emerged from caveman hunter ancestors, and therefore they require a high animal protein/meat diet.
The author also suggests that certain blood types should avoid some foods at all costs, because to eat foods that are genetically inappropriate causes lectin deposits that agglutinate your blood. In other words, substances that naturally occur in the foods you eat cause blood clumping that diminishes blood flow and clogs vessels and organs.
Unfortunately, the reasoning in this popular diet plan is flawed and not backed by research or studies.
The result is that people who adhere to this type of an eating plan may be eating foods that do not contribute to good health – no matter what your blood type. Furthermore, the people that have experienced positive results from the plan may simply be cutting out some processed and allergenic foods that anyone would improve from, regardless of their blood type.
About Blood Type
There are eight basic blood types. The most common type, O+, is present in about 39 percent of the population.
This is followed closely by A+ and B+. Your blood type is determined by the type of antigens existing on the surface of the red blood cells.
These antigens determine whether blood type is A, B, AB, or O. The other factor that types blood is the Rh factor, which is expressed as + or -.
Blood type is genetically inherited from both parents; however, it is slightly more complex than just directly passing on one or the other blood types of the parents.
For example, according to the Red Cross, a child with both parents having the AB blood type can have A, B, or AB. A child with parents who both have a blood type of B may have either Type O or Type B blood, and so on.
Blood type is important for blood donation. For example, someone with Type A blood can’t donate to someone with Type B. This is because when the body receives an incompatible blood type, it sees the foreign blood as an invader.
This leads to an immune response that causes clotting. How the blood type affects our body’s response to the foods we eat, however, is much less clear.
Debunking the Diet
One of the claims in the blood type diet is that Type O is the very first blood type that existed, present among early hunters. Microbiological research, on the other hand, suggests that the original blood type was A.
Since the blood type diet begins with such a flawed premise, it is not surprising that its hypotheses and recommendations are flawed, as well.
One of the biggest flaws in the diet I see is this: The author suggests that the human species as a whole does not have an ideal diet.
Rather, he states that subgroups within this species (in this case humans separated by blood type) each have distinct ideal diets that vary extensively. This is not something found in nature.
In fact, if you look at the animal kingdom, every species has an ideal diet that suits the entire species.
For example, consider gorillas or cats. All gorillas or cats do best with a certain diet, and that doesn’t change wherever you’re feeding one. Why should people be any different?
Every human being has the same anatomy and digestive tract, and therefore the way we process the foods we eat are roughly the same. While genetic inheritance and upbringing may give rise to certain things such as susceptibility to disease, allergies, food sensitivities, and many others, reactions to food have more to do with individual genetic tendencies.
That’s why you can and should determine and eat the specific foods do best for your body. But to apply those to a broad group of people based on blood type is false, and it can mislead people into eating foods that aren’t best for humans as a species and avoiding those that are.
Another claim the blood type diet makes is that lectins from specific foods only cause agglutination of specific blood types. Research seems to show the opposite. Very few plant foods contain lectins that react with specific blood types; however, animal foods are more likely to be blood type specific.
Likewise, lectins are in virtually every food human beings eat – plants, animals, grains, nuts – so avoiding them is nearly impossible unless you eat a grossly restrictive diet.
Humans have been eating lectin-containing foods since the beginning, yet many of the health issues of civilization (diabetes, metabolic syndrome, etc.), have only come about in relatively recent human history.
Many experts also refute the blood type diet, saying that it lacks solid backing in research.
The bottom line is this: the blood type diet lacks solid, controlled studies to back up the author’s reasoning.
Likewise, much of the diet’s reasoning is based on a faulty premise. It also doesn’t fall in line with the laws of nature whereby a species as a whole has a general, ideal natural diet, based on its anatomy, digestive tract, etc.
How to Eat
I am an advocate of plant-based diets, which are tailored to the human digestive system and meet human nutritional needs ideally. I believe anyone, regardless of blood type, can benefit from an alkaline plant-based diet rich in enzymes and nutrients to achieve optimal health.
You can keep a small amount of animal protein in your diet, if you would really like to, but this should be limited, no matter what your blood type.
If you eat too much meat your body will become overly acidic.
See which foods your body digests the best and that you feel the best on, and avoid the ones that don’t specifically work for you. Keep meals more simple, for better digestion.
YES!
I have been following Natalia Rose’s Detox 4 Women approach for 14 months, and have just discovered your book and I am incorporating some of your philosophies like GGS a few times a week, etc. My concern which has been only a recent concern is when I viewed Gil Jacob’s video “When Veganism Doesn’t Work”. I am a Type O, but I haven’t eaten any meat since last July. I do eat the occasional fish and I do eat raw goat’s milk or sheep’s milk cheeses a few times a week at dinner. Do you have any thoughts here? I don’t feel as good as I felt when I first started this regimen. I discovered your book through a written interview from Gil Jacobs by the way. Thank you and I love your book and recommend it to my friends because of your approach; I love the first phase Blossoming Beauty for people who are coming off a SAD.
I really like Natalie Rose’s book, The Raw Food Detox diet .. my fav is her ambrosia salad with liquid gold elixer dressing. I can’t follow her diet for more than a few days as I’m starving .. I’m type O and I do feel that I need to eat animal protein to feel satisfied.
I also like the glowing green smoothie here (minus the celery). I like to take parts of eating plans and devise my own diet :-)
Thank you for this! I was told by a holistic medicine practitioner that I should eat lots of meat because I have type O blood, but I was having a lot of digestive issues at the time including constipation and bloating, and I knew that more meat would not help. Not to mention, if I eat meat more than twice a week, I feel less energetic than when I stick to a vegetarian diet. Thanks as always for looking out for our well being Kim!
That’s great Jenny! Yes you must always customize for your specific body, and nourish yourself the way that works best for you. xx
Out of all the “diet plans” I have seen over the years. Yours, Kimberly, makes the most sense. I still eat animal protein on occasion (hard to cut out completely when you have a family of meat eaters) but I try to make sure our food is 100% organic, grass-fed, or range-free whenever possible. I juice daily or have vegan-based protein shakes. It is challenging in the world we live in today but I am so much better for it. You have inspired me to eat close to the earth.The way it should be for optimal health. Thanks for all that you do to inspire others and promote a healthy society. The world needs more people like you!
Thanks Shawn! It sounds like you have struck a good balance for you and your lifestyle. Keep up the great work. xx
What is your recipes for vegan shakes? I want to do this, but need help, I too come from Hunters and Meat Eaters, this is a tough diet, yet feel better already, only on my 3rd day, but it is working and I am 60 years old. Thank you for this post, seems most like “me”.
I really enjoyed this post. I certainly agree that people have evolved since the caveman days and have the same digestive tract so there are basic principles that make sense for us all. Are you familiar with Ayurveda? If so, I am curious to hear your thoughts on the Ayurvedic principles of eating for your body type (dosha). Thanks!
Hi Laura, I am. Again, I personally think that you have to individualize, even beyond dosha. It can shift with what is going on in your life, the time of year, so many dozens factors. As a Vata Pitta I am meant to eat/not eat certain foods, but I have found that I am vastly different from other Vata Pittas, and those dietary restrictions are not necessarily helpful to me.
Customize for yourself! xx
LOVE this article. Thank you!!
A friend of mine followed the recommendations in the blood type diet and got her bloodcount up from 7 to 11 without using meds. She would have become much more conscious of what she was consuming, but the guidelines in the book did seem to help her.
Like I said, I think the general guidelines can make people more conscious of diet overall and avoid processed and allergenic foods, so improvements are not necessarily indicative of the actual success of blood type specific dieting.
Nice!! I used to follow a Type A diet (which fortunately was mostly vegetarian) but soon realized this had no scientific evidence whatsoever. I think soon people will begin to realize that the popular paleo diet (one I also used to follow after btd) is a fad after all…Dr. McDougall, Dr. Esselstyn, Dr. Campbell and most importantly the Primitive Nutrition series on youtube helped me realize this :) Oh and yes, you too, of course!!! hehe
That’s great Stephanie. Dr. McDougall is one of my long-time favorite doctors.
Hi Kimberly you mention “research” to support your argument. Could you post sources for me to review? Thanks.
Hey Kimberly, could you do a post on chronic dehydration and ways to reverse it? I would greatly appreciate your thoughts on it!
Brilliant as always. Thanks Kim! I love it when you debunk diets for us :)
If I recall correctly, Weston A Price said we should eat based on the diet of our ancestors. Much easier to do if the ancestors of your parents (and up the line) come from one area. What if one ancestral lineage is from S. America and the other from Western Europe? Those two groups ate very different staples.
If both parents have type AB blood they could, as you pointed out above, have kids with type A, B or AB blood. If you believe the Blood Typing Diet ancestral theory, then three different diets would need to be followed in that one family. Yet… the kids all come from the same ancestry so why would they need three different diets?
I was curious and did a quick search for blood type by ethnicity. There are some groups that had a very high predominance of one blood type over another. Many were spread among the four main blood types. I’m curious if the ideal diet is similar in ethnic groups in which one blood type was shared by 90%+ of the group.
Thanks for this, Kim! I am a type O- and never like being told that I should subsist on an all red meat diet. :)
Although I’m not a scientist, I feel that the Blood Type diet is a good diet for me. My blood type is O and I am not supposed to eat dairy, caffeine, refined carbs (bread), and sugar. I feel great on this diet, but .. I am lazy and revert back to say, eating a sandwich when I should eat a salad and protein.
I don’t think one eating plan fits all .. eat to suit your lifestyle and health. Life is too short to not eat a slice of pizza :-)
Your information has literally been the key to my self worth and self confidence and I am interested in going into the health and wellness industry with the message of how directly connected health is to self esteem and confidence and I would really loved to know how you got started and your advice on how someone like me can continue to spread this message as well.
I was born with a physical difference known as Amniotic Band Syndrome which has caused me to have missing and disfigured fingers and so my message will be geared towards those women with physical differences who in a sense don’t feel like they “deserve” to be healthy or happy.
Thank you Kim! Bless you and keep doing what you do!! ;-)
Thanks so much Kim for posting this!!! I have been so confused as to which diet really is best for me. I have read the blood type diet and found it really interesting but as Sue posted just above, I am an O blood type but my Mum is an A, my Dad is a B and my sister is AB so it made it very hard to follow a diet specific to me when all the corresponding diets conflicted. I’ve also followed a Paleo diet as this pretty much corresponds with an O type diet as well. It cuts out Grains – specifically wheat and Dairy which I am intolerant to so this made sense to me but I’ve read your book and seen how a vegan diet can really heal sickness and give more energy. Your reasoning also made a huge amount of sense to me as my Mum has eaten a vegan diet for 9 months and said she feels great but I wasn’t sure if that is because she is an A type blood.
Can I ask if you know of any of your clients who are an O blood type that have thrived off a vegan diet? I’d be really interested to see how it affects them. Thanks again :D
Wonderful words of wisdom as always. I love eating the Beauty Detox way. I feel fantastic and I can’t imagine ever going back to eating meat after being vegetarian for more than 3 years.
I always look forward to your post.

Hmmm…all I know is when I ate all the beneficials off the lists (A+) I lost a great deal of weight, my skin cleared up and I felt amazing. I had many people tell me I looked amazing and wanted to know what I was doing. Prior to this my eyes were always puffy and my face looked disfigured and tired looking. I did not look or feel my best.
Blood type diet was a game changer for me. I will always use that list for my fruits,vegetables, grains, nuts, seeds.(Alkaline)
Also feed my type O son, husband based on the beneficial fruits, vegetables, grains, nuts,seeds and avoid the red meats…positive results. I just know it works when I avoid the avoid foods from the fruits, vegetables,nuts, seeds lists.
I agree. I have suffered with many immune and blood disorders I also ballooned up to almost 300 lbs thanks to the drugs I was being given. Once I started Dr. D’adamo’s Blood type B food list, I immediately lost weight, 3 LBS the first day! and started feeling better, getting up at 8 am instead of 11, feeling alert, less foggy, sores that no doctor could explain on my feet started to clear up…I do not care what research says….I care what my body says….and man is it talking!!! besides all this research seems to result in a lot of commercials asking if you’d like to file a claim because you’ve been harmed by some pill, the research said was fine to take! Ha research is not written in stone. And “Popular opinion” is changing all the time.
I AM a 100 percent believer in the blood type diet I first came across the diet in 2004 I was seeing a dermatologist for my adult cystic acne And the dermatologist couldn’t help me cure it I heard about the diet found out my blood type was A+ and I was eating honey tangerines and oranges every two weeks when I would get paid from work I also had cystic acne on my scalp so when I read that oranges interfere with absorption of minerals it hit me like a ton of bricks it was causing me to have a hormonal imbalance because of the lack of minerals being absorbed immediately I eliminated organges and tangerines and my skin immediately cleared all the way up and I have help many blood type A people on my job and customers clear up their adult cystic acne by eliminating oranges and orange juice
Yeah, Monica, you got it right! I am an o+ and never tried to follow an eating plan around my blood type. I have been following a more vegan diet the last 17 mos. and honestly can say I don’t feel as good as when I was consuming animal protien. I know there is a detox stage, but after a year w/out animal protien, I don’t feel any better. In fact, I feel weaker and have lost a lot of definition in my muscles despite continueing the same workouts. I wish I could thrive on a vegan diet but I’m beginning to believe that this is not the best for everyone. I believe a diet should be based on bioindiviuality. I think Weston Price’s study proved this. He hoped to prove a vegan diet in ALL groups promoted longevity but was surprised to find that this was not true.
Kim,
Thanks for this post. I needed to be reminded to eat the foods that my body has resonated with based on past experiences. I think I’ll start keeping track of that more often…
Do you think you could write a post on the chakras and how to clear them using nutrition/yoga/meditation?
Thanks,
Kristen
Thank you for publishing this. I have been upset about what was supposedly bad for my blood type (tomatoes canoloupe etc) but eating it anyway. This feels like a huge weight is being lifted off my shoulders
This is so true. Blood type controls the production of antigens on the surface of red blood cells and therefore has an impact on the immune system and blood composition. But there is no reasonable thought process that could link this to your digestion because your rate of respiration does actually influence how your body digests different foods or its macronutrient requirements! Nice one Kim.
I do not eat anomal protein for many reason besides being acidic , but recently heard that many legumes fruit vegetables and nuts are acidic also so what to do now
I discovered that I was not lactose intolerant, but in fact soy intolerant thanks to the blood type diet. I also learned that I don’t digest corn or wheat well, all without doing elimination diets, but by following the diet recommended for blood type B.
I was vegetarian for 9 years and ate well but always felt tired and often sick. I’ll never be someone who eats a great deal of meat, but honestly feel more energetic and mentally agile when some of my protein comes from animal sources, as much as I wish it didn’t.
I can’t agree that all humans have the same basic nutritional needs – it doesn’t take a laboratory to tell you that three women eating the exact same foods for a week won’t necessarily have the same physical reactions, just spending time with friends, cooking and eating together.
I’m an O, but didn’t know my blood type when reading the book years ago. I was convinced I was an A since I’d been vegetarian for year and when I found out I was an O, I was sure my test got mixed up with someone else’s. Needless to say, I ignored the book and continued eating plants. I went vegan a little over a year ago and never felt better. Thanks for sharing that the book is not based on good science!
oh my goodness, this sums up my experience so well! i thought someone had mixed up my blood tests as well. i still get some bloating eating vegan, do you have any ways to work around this?
Hi Kim! Thanks for everything! You are amazing! Any good recipes for Walkame? In the new book? I saw it on the BDS shopping list and tried it and loved it!
Thank you for this post!
I have studied cultural nutrition and am now working on the nutrition guidelines for schoolchildren in the US. Whenever I here about the blood type diet or the paleo diet my response is always “please remember that our hunter gatherer ancestors rarely ate meat and that the meat was much different than it is now”. As you said, there are some things in these diets that are common sense (not eating refined grains or dairy), but the fact of the matter is that eating plant based diets are the best for us as humans. Even if you do choose to eat meat, organic grass fed (or even wild meat) is best! I love your glowing green smoothie, it sure hits the spot. Along with the your recipe I juice a beet (red or golden) in place of one of the apples with it now as well. Hopefully our government will begin to listen to science rather than money for the health of our schoolchildren . I recommend The China Study to all those I work with.
Kim, what blood type are you?
A healthy gout diet is important to help prevent recurring gout causing some serious health problems. Natural Dieting Plans
We all know that the goal of Big business is to make money so lets keep the people sick so that can keep coming back for more drugs, instead of following a plan that will not cost too much money. This is really bad medicine to keep people on laboratory chemicals instead of teaching people to eat healthy from the start to prevent cancer and diseases.

Hi Kimberly,
According to the Blood type diet book, I should not be consuming coconut oil or sprinkling cayenne pepper on my food if I am a AB+ blood type. What are your thoughts on this?
Thank you!
I am an o and totally struggle with getting off the btd. I have been on it for 8 years and felt pretty good except the last two years, I am struggling to keep the weight off.
Also, a celiac individual.. I am confused about what to eat anymore. :(
Yeah its necessary to know that which diets suits your body or which not.
I’m an o+ and I have never been sicker than when I was a vegetarian or when I was a vegan. Right now I’m on the Paleo Diet and have never been more happy or healthier. I”m also an avid sprinter and my performance has increased since using this diet. While I am unsure about the blood type diet, many people rave about it. and I find it interesting how the healthiest I have been has been on a diet that happens to follow the rules of the blood type diet.
What was your diet mainly comprised of as a vegetarian and vegan?
I started on the Type “O” way of eating back in the year 2000. Slim, few wrinkles, 2013 I will be 90 years old.
No complaints.
I am A+ and most of the foods I enjoy are on the banned list. I am morbidly obese, but I do not like the vegetarian lifestyle that the A Blood diet plan outlays, any ideas? I’d like to stick to it but I would have been better as an O bloodtype.
RM, I can feel your pain. I am an A+ as well, and used to be a big time carnivore. I’ve always had an itch for going vegan, but never really had the guts to do it as I love meat so much… I read the blood type diet book a few months ago and decided to follow it. As you probably know, the animal protein intake is very limited… limited to a little chicken once or twice a week, no dairy, etc.
I now drink soy milk 100% organic (my old self would fall off her hair just by reading to this post), I quit eating beef (and oh those wonderful grilled cuts), pork, bacon… you name it. I eat one or two eggs, once or twice a week tops, and try to base my diet on the approved vegetables and fruits. I also eat a lot more nuts and legumes now (beans and lentis have become a part of my weekly routine). Yeah I break it now and then, but I haven’t felt better in my life.
I have more energy, I sleep better, I feel lighter (I also do some yoga a few times a week) and that “brain fog” many people talk about is gone. I am a happy person. I am starting to look better, and slowly losing weight (I eat a lot of carbs: breads, buckwheat noddles, rice, rice noodles you name it — even some PB). All those foods that I always thought were the cause of my upset stomach I’ve come to realize were not the problem. It was all the foods I wasn’t supposed to be consuming and yet I did.
It hasn’t been hard to stop eating meat. It’s been more hard to find somewhere to eat when I don’t cook at home that provides meals w/o meat. But I don’t even crave it at all (seems impossible huh?) Every now and then I get out and receive that delicous smell of a nearby grill, and drool for 10 seconds then off I go. Try it , you can always go back if you don’t like it ;)
You could definitely see your enthusiasm within the article you write.
The sector hopes for more passionate writers such as you who are not afraid
to mention how they believe. At all times go after your
heart.
I haven’t felt really “good” most of my life. I work in the medical field and the suggestion of getting a live blood microscopy was completely frowned upon. A friend convinced me to go saying, “what could it hurt”? I made an appointment, for her sake, and found the entire processing fascinating. I was eating the opposite of what my body required and tolerated. I’m not easily convinced unless I see can see the proof for myself. Been on my new A positive blood diet now for over a year and have never felt better. Weight is in check, I have energy, and it’s helped with my attitude and improved my “brain fog”. This may not work for everyone, but it’s given me new life and I’m not switching! BTW, ran into a nurse at a clinic who looked absolutely fantastic – I could see she dropped a lot of weight, but it also look like she had some “things” lifted; she was gorgeous. I complimented her and pushed for answers as to her secret for looking so fantastic. She said, “please don’t tell anyone, but I had a live blood microscopy which revealed I was eating incorrectly for my blood type so I decided to go for it and switched my diet”! In the medical community, this is not something we speak of as it’s considered “quackery”, She is proof positive this blood diet really works. She’s completely changed and, no, she had nothing “lifted”! LOL
I’m type B and have only been following the plan for a month. I feel better than I ever have. It’s indescribable how great I feel, just amazing!
Thanks!
All these responses just prove that every “body” is different. The answer seems to be to stay away from processed foods and choose either blood type diet or solely plant based or a combination of both as long as it keeps you healthy and feeling good, Research is great and necessary, but it can be “cheap info” if not conducted properly, I.e control groups, long term vs short term and esp amount of people in the study!
Interesting post. I run a not nearly as popular nutrition site as Kim’s. I will say that I advocate the Blood Type Diet (BTD) as many other folks on here. I experiment on myself first so I can speak from experience, and as a blood type O it’s worked fairly well for me. But there are certain areas where I disagree with BTD, and it’s part of knowing yourself and what works best for you. For example, even though I eat meat, I try to make it count for only 1/3 of my meal portion. You should still eat plenty of veggies. And Kimberly’s advice on the detox/plant-based bit is excellent. I’m a big fan of juicing … particularly in the summer. Cooked veggies “feel” better in the winter. Following this route and exercising regularly has me looking 15 years younger than my age. But big props to Cayley. I’d like to know her secret!
Actually, this blog is inaccurate when stating that no other animal in nature has specified diets amongst different subcategories of the species. Some monkeys are omnivorous, and others are strictly vegetarians; we mimic these animals.
Which monkeys are omnivores and which ones are herbivores? I think monkeys are mainly opportunist that eat just about anything they can find, just like humans.
One “species” of monkey versus another “species” of monkey – they are not all the same species.
I blog frequently and I seriously appreciate your information.
This great article has truly peaked my interest.
I am going to take a note of your blog and keep checking for new details about once per week.
I subscribed to your Feed as well.
For about two years I did the type o blood type diet. I felt better, but I think because I started to cook for myself more. This became a nurturing activity that I’ve grown to appreciate. I ate more fresh veggies and lean meats, I cut out flour and most dairy and started to bake and experiment with gluten free snacks and breakfast foods. I did find that many of the foods allowed for my type was food I already consumed. After watching Forks over Knives I really started to think about changing my diet. It struck me that as an O type, and the longevity of folks back then, well they really didn’t live long. It probably was not due to their diet, but it made me think that changing from blood type to plant based is not such a bad idea. I seem more bloated after not eating meat, I have had some on occasion but not as much as I was having. Interestingly enough, I really didn’t eat much meat before i started the blood type diet, especially red meat, so this swing is back to more what I used to eat. I did loose some weight on the blood type diet, but I think it was because of taking out the flour and eating more fresh foods. I’m so glad I can eat avocados again :)
Thank you for posting about moving back to the plant based type diets….I was reading about the Blood Type O diet and was very very sad….I love avocados.
Undeniably believe that that you stated. Your favourite justification seemed to be on the net the easiest factor to remember of. I say to you, I certainly get irked at the same time as other folks think about worries that they plainly don’t recognize about. You controlled to hit the nail upon the top and defined out the whole thing with no need side effect , other folks could take a signal. Will likely be back to get more. Thank you
I did the thin deluxe diet, and lost over 100 pounds in less then a year. I was eating 2 fruits a day, 4 – 6 cups of veggies, 3.5 oz protein at lunch and at dinner. I have to say this diet gave me my life back. I wish I could post my pictures.
I found out while doing the Thin deluxe diet that I was allergic to wheat & dairy. I never felt better then while I was on that diet. I lost so many inches. I now will never go back to eating like I used to eat.
I’m now eating all fresh veggies and fruits juicing, and am healthy. I’m following your blog, and find it interesting.
I love your blog Kimberly
Thank you for being here for all of us with your information.
That sounds like the HCG diet protocol.
4 cups veggies a day
3.5 oz protein, twice a day
2 fruit.
Totals 500 calories. Of course anyone will loose tons of weight on that. I did. But I could never have been on that low calorie without being starving. The HCG drops release 2,000 calories of stored fat from your fat stores , so you can eat 500 calories and feel full.
Thanks for your marvelous posting! I genuinely enjoyed reading it,
you’re a great author.I will ensure that I bookmark your blog and will often come back very soon. I want to encourage continue your great posts, have a nice holiday weekend!
I disagree on the myths of the blood group diet. The blood group diet works beautifully ! I was eating the opposite of what i should have been and ended up getting thyroid with goitre enlargement. I had to have a surgery to remove the enlargement and all because i was eating the wrong food. Not enough iodine and a lifestyle based in Gluten , fresh vegs & Fruits. I was a vegan but owing to health issues i followed the Blood type diet and my life changed.
I got rid of sluggishness only due to the blood type diet. I would recommend that people should adopt the type of diet that suits them the most.
Im a fanatical reseracher, I have to read everything I can on something before I do it, My Mom told me about the BTD, and Ive been at the end of my rope lately, so Im ready for something to work. Im sluggish, Cant concentrate or focus, I just gained 12 lbs in just over a month and I havent done anything different…except turn 35! I know getting my Thyroid checked is the next step, since everyone in my family is Hypo, Im sure it was just a matter of time. Ive done the Daniel Fast a couple times, which is a highly restrictive vegan diet. I dont do well on it at all. I get so tired and bloated that it hurts, I obviously need protien and lots of it for energy, and to keep the bloating at bay. I love beans but they hate me, the o postive diet plan cuts them out …makes sense. But to cut out all dairy and eggs? This will be the true test since its my go to when Im too tired to chew when I get off work. This is a ray of hope for me, I hope I can join all of you with rave reviews. Thank you for the insight.
After many years of looking for the perfect diet I finally came across The Blood Type Diet and it was the
absolute piece to the puzzle and life changing…… sometimes the answer isn’t in science but realizing that we are all different and what works for one doesnt work for others….
I’m so glad I read this. I was starting to panic when reading the B diet as I’m quite allergic to seafood and really don’t like any meat except Chicken. I love everything on the “do not eat” list and pretty much don’t like everything on the “eat” list. Peanut butter being one of the biggest items! I resigned to the fact that I would just be “unhealthy” according to the Blood Type Diet. Thanks to you… in a matter of half an hour of researching the Blood Type Diet… I have hope again. :)
me too… I didn’t eat vegetables and prefers chickens and meats all the time, wheat for breakfast and my daily dish includes all listed in the avoid list type for my blood type, B. Kind of relaxed when I’ve found this blog as I just can’t believed I’ve been poisoning myself since forever. thank you~~
Blood type diets for O , specifically say not to eat raw broccoli. That it has a toxic effect. Not just on thyroid/goiter, as the other cruciferous veggies, but that it is actually a poison in high ‘raw’ doses. So suggests not to you in juicing.
your thoughts?
Right away I am going to do my breakfast, later than having my breakfast coming yet again to read additional news.
I am A+. When I read the BTD for my blood type, it blew me away. It was so spot on that it was scary. I really don’t do diets. My system is so sensitive that I couldn’t do them anyway. The BTD is not really a diet. In my opinion, if it works for you, do it. Kimberly, I respect your opinion, but the BTD isn’t selling any products. That, in itself, peaked my interest. I think that it is all personal; to each his own. If it makes you feel bad and you eat it anyway, that’s your business. If it makes you feel better, then go for it, that’s your business too. What works for one person will not always work for everyone. That is a proven fact. It is also proven that when it comes right down to it, it is always about the money. Someone posted that doctors will never cure everyone, mainly because they would go out of business. I believe that, in fact, I have spent so much money on consultations, follow-ups and procedures that were completely unnecessary. I’ve been hospitalized just for the money. I was told this by a nurse in ER once. She was absolutely correct. My hospital stay was just a way for the hospital to make money. I did not learn a thing from that stay in the hospital. I was referred to my primary physician who treated a middle ear infection with antibiotics. What a waste of time and money. We know our bodies; all we need do is listen to them.
I’m have B Type blood, and after having headaches for years, I read that B types should never eat chicken, which I did very often.
I stopped eating chicken over a year ago, and for the most part, no more headaches. I used to eat corn and other corn products, like popcorn, and would always gain weights. After learning again that B types should avoid all corn products, I did, and I dropped 20 pounds, and now weigh in at 157, which is perfect for my height. And, I feel great, and have tons of energy, and take NO medications at 61 years young.
So, this blood type diet (it should be called a lifestyle, as its not really a diet) is the real thing, and should be taken seriously.
Were you eating natural chicken and corn products? When I hear chicken and corn I think hormones and GMO. I would blame those before saying a “Blood Type Diet” works…
I have O+. I invreased mu lean meat/red meat intake by 50% and completely cut grains and dairy out of my diet considering that it is highly toxic to O’s. it’s amazing how much weight I have lost and how I am in TIP TOP health for the first time in 25 years of my life. I have no more digestive issues as well. I had numerous gastrointestinal and stomach issues prior to the diet. Now they are non existent. It’s not a diet.. It’s a life style.
We have an A, two O’s and a B in our family. I had begun to develop crippling arthritis in my hands. The
BTD cured it in 3 days. My 9 year old had suffered from terrible allergies until we got her on the BTD.
My husband has lost weight he couldn’t seem to shed by getting off meat…he’s an A. It all makes sense
to me. We are not all the same. You would not give an O type a transfusion with A blood….why would you
not believe that different blood types need different foods. I don’t believe anything I read…I try it out.
I was a vegetarian for years and felt like a ghost. I’m an O and I now eat animal protein and not grains.
I’m alive again. My A husband has stopped eating meat and looks ten years younger. Proof is in the
results. People should try it before they make up their minds. It’s spot on in my opinion….from experience.
A lot of the people posting comments here can’t see the forest for the trees! Of course you lost weight on the blood type diet: in no blood group section does the diet mention potato chips, fast food, or fizzy drinks! I bet most of you would have lost as much weight regardless of which blood group specific aliments you would have eaten. As someone here mentioned, they gave up popcorn, because they were a type O. Well, popcorn, especially accompanied by considerable amounts of salt or other additives, is unhealthy for everyone, not just the O blood group. So giving it up is obviously going to lead to living a healthier life! If one followed the A blood type diet, they would probably have to stop eating from KFC. And THAT is what makes one lose weight! A diet based on blood groups is just as efficient as one based on hair color: what’s to say people with darker hair aren’t supposed to eat more meat? After all, the first people, and hence “the hunters” had dark hair and dark skin.
I’m a type O and have been a Vegan for two years. Giving up meat has been beneficial to me but also giving up a lot of what was on the list seemed to do wonders for me. No grains at all, I cut out beans and the fruits and veggies mentioned as avoids as well as the nuts. I was told by my doctor I’m not a soy guy but I use tofu and tempeh as my food proteins and have to this point been fine. I also eat cinnamon and nutmeg and haven’t experience any problems. So like you said, striking a balance
I have been vegan as well, out of ethical reasons. But if you cut out grains, most of the beans and nuts (considering a vegan does not eat milk and eggs in addition to the rest avoided by vegetarian ) I wonder what you can eat to keep up with necessary Kcal (intelligent calories, not only sugar based), not to mention the rest.
Kimbery i appreciate you’re position, but you are wrong in regards to all humans being able to eat the same diet simply because we all contain the same digestive track. that would be like saying everyone can drink the same amount of alcohol because we all have a liver. Isn’t the avocation for avoiding certain foods based on blood type similar to avoiding certain foods because of sensitivities or allergies? I would love to see your explanation on how the consumption of white rice (the main carb and grain staple in most asian and latin cultures) effects each group differently, being Hispanic, i know the heavy consumption of white rice lead to massive weight gain, people attribute that to genetics. But then i have asian or pacific islander friends who consume white rice throughout the day and are insanely lean. Is that because they eat more fish? ha.
as i said, i appreciate your opinion but as for myself, following the blood type diet i cut out all gluten from my diet for a long time. on a two week vacation where pretty much everything i ate was pasta, pizza, and or bread i became insanely sick. turns out i have Celiacs disease. Now i dont know if thats coincidence or not, but it turns out that the blood type diet has been right for me. also, following it, i have dropped from 230 pounds to 169 pounds in a little under a year.
I have learned new things from the blog post. One other thing I have recognized is that normally, FSBO sellers will reject you. Remember, they can prefer to not ever use your products and services. But if anyone maintain a gradual, professional partnership, offering aid and remaining in contact for around four to five weeks, you will usually manage to win a discussion. From there, a house listing follows. Thanks
I do not believe you have sufficient evidence to debunk this. Some of your reasoning are just silly. Certain breeds of animals DO require different diets for optimum health, and furthermore, I believe it is fairly obvious not all humans process food the same way (eg. some people are diabetic, celiac, lactose intolerant, etc.) This does not give evidence in support or against the diets for bloodtype. I consider myself a healthy person and when I eat they way I feel my best, it’s actually almost exactly the suggested diet for my bloodtype. I think this needs more research.
Jane, Kudos on the website very nice, But I do have a couple of concerns.
I suggest your research ” Otzi ” who happens to be the oldest remains of a preserved human……Discovered in the early 90’s . And quess what his his blood type is?
Ohhhhhhhhh your minus whats behind the sinus . :-) Also if everone’s anatomy is the same, can you please explain why drugs and medications interact differently . what might cure Tom, could kill Harry. I just saw on your last comment you addressed this kinda. But I do suggest that you use more discernment in the future.
Best regards,
Troy
Let”s see, I’ve tried only two different diets in the past decade, and following my blood type (O) for the past two months has been absurdly beneficial. I’ve lost 30 lbs in the past 60 days, have a lot more energy, less pain from my fibromyalgia and overall, just feel a lot better. And mind you, this loss of weight, etc. has come with ZERO working out/exercise changes, just the diet change alone. So, yeah, maybe for a few non-believers it seems outlandish or whatnot, but, for a person that doesn’t really put any weight into ‘fad’ type diets, I was a bit overwhelmed by the fact that this has been so very successful.
I think you are missing the point about the blood type diet. Yes it has flaws , but how can it be possible that blood types behave the same biochemically? Liike different ethnicities are sucseptable to different diseases. I think this idea is fascinating. I am o pos, and have slowly been converting to the o diet before i even heard of it. Like as if my body is craving healhier foods suited to my own metabolism and boichemical makeup.
Yes we are all the same species. But we are also individually unique as finger prints prove. And to go deeper still, we cannot exclude our gut flora in relation to blood type. I believe that the main blood abo anti bodies have formed to fight e coli. Why else are there abo anti bodies? Certainately not to only fight fetal bleeds often seen in child birth.
So since i believe the whole gut flora /blood type interaction, i think the blood type diet is a fascinating hypothesis and should be government funded. It could be the next best thing since rhogam!
I also believe diabetes and other metabolic diseases have been around since humans have walked the earth. It wasnt till recently we gave them names.

I gave up eating red meat and poultry about 25 years ago, for ethical reasons. I still ate fish and seafood but started getting my protein from beans, dairy, etc.. I have followed Eating For Your Blood Type off and on over the years and know others who have experimented with it. I’m an AB blood type and found that the food I had gravitated to, was for the most part, foods that according to this diet, would agree with me. One day my mother was cooking a turkey and I was literally salivating. I hadn’t experienced that kind of reaction in years, so I went with it and had some turkey. I started to include turkey in my diet occasionally and then the same thing happened with chicken – CRAVED it. So, I ate that as well for awhile. Now they both repulse me once again so I don’t eat them. I also worked for a Naturopathic doctor who was an O Type. She wanted to go on a vegetarian diet, but after cutting out red meat protein, began to suffer from declining health. She went back on a red meat diet, and her health improved notably. I guess what I’m getting at, is I don’t think this diet was intended to be the be-all-and-end-all, but rather a guide. I like the Blood Type Diet, personally, and think there is plenty of truth in there, but it doesn’t completely fit me, nor do I think it was intended to. Listen to your body. If it works – great! If it doesn’t – find other sources of information. ♡
Well.. I must disagree with for a simple reason: both my wife and I tried this diet in 2004 for 8 months, the results: I lost 6 kg (was slightly overweight) and my wife lost 8 kg (was slightly overweight) and most importantly we were full of energy, we use to wake up before the alarm clock (and have s–). We stopped it after a while simply because we were craving the foods we weren’t eating.. but today we’re back on it and fully convinced.
The blood type diet changed my life. I was eating very healthy before but had numerous health problems. Since I started the blood type diet 2 years ago I have been able to overcome my health problems. People do not digest all foods the same way. The paleo diet made me very sick! Many people I know were able to overcome health problems after following the blood type diet. Personal experience and seeing others recover from sickness has made me understand that one does not fit all.
Killer whales off the cost of New Zealand adapted to eating sting rays. That’s the only place in the world they eat them. Different pods eat different diets, so saying that animals all eat the same diet is just ignorant
Im blood type o and tried many diets when I ate according to the type o diet I lost 40lbs in three months and never felt so happy,energized lighter in my life.I got married and went back to my old ways and gained 80lbs and now I ready to change my bad eating habits for good this time. I realized just cause im happy doesn’t mean I can just eat whatever I want

Thank you!
Do cats and gorillas have different blood types? I don’t know if it is only humans who do. So is this a valid argument if they don’t have different blood types? And where is the evidence that the statement that cats and gorillas the world over eat the same diet? What kind of cats are being discussed – big cats, domestic….
Furthermore, implicit in the statement: “the author suggests that the human species as a whole does not have an ideal diet” is that there is an ideal diet for humans. However, as humans range over such a large variety of ecosystems, not all diets are the same. The Bushman of the Kalahari eat differently to the Inuit to the people of the Amazon. So how can it be argued (even if implicitly) that all people should have the the same diet?
The discussion of blood type and Rh factor is deliberately objuscatory. The Blood Type Diet makes it clear that Rh is not relevant to the issue.
Whole populations of humans can develop particular commonalities in blood that are not seen in other human populations, for example, sickle cell anemia in Africa. While this is not related to blood type but more a response of the human organism to the selective pressure resulting from the combination of a mosquito borne disease and bood cell disease causing the “ill” to be successsful at surviving because they do not succumb to malaria. It does show that there is not a one size fits all when it comes to the funtion of blood in the human species.
in regards to blood types, yes cats and gorillas have different blood types. Gorillas, similar to humans and cats have more than humans.
I am O+ and this diet does not suit me at all! I cannot tolerate red meat…takes me forever to digest it. I CRAVE avocados (on my No NO & NO list) and eat 1/2 of an avocado EVERY day on a large salad. I also drink a mocha every evening which I make with skim-milk (also on my NO list) to no ill effect. Eat whatever works for you as long as it’s healthy in general. I am very healthy and have tons of energy. I do a vigorous workout 6 days a week. Never felt better and I am 69 years old. I DO feel better since making large salads the bulk of my evening meal and going gluten-free (actually rarely eat any grain) however.
i’m an O-, and veggie/vegan for about 15 years. A friend just started the btd and is cutting out nightshades and most meats, she’s an ‘A’. I’ve never felt better or had more energy than when I was vegan. Just out of curiosity, I’m adding more protien (eggs and nuts) to my diet and cutting out the many fries and tostitos we’ve been eating due to our gluten intolerance. I’ve been losing weight of course, anyone would by avoiding deep fried foods. But I’ve been getting extra tired as well. I refuse to eat animals, so I may chalk it up to experience and go back to being mostly vegan and GF, since that gives me the most energy.
I’m a O type had many health problems before changing to a vegan diet, won’t be changing back to the O diet that’s for sure !!!
O Negative is actually the oldest blood type, not A positive. I stay away from gluten as I have an intolerance and currently a vegetarian but have noticed a decline in my health since becoming a vegetarian, so I may incorporate some fish back into my diet. I have to say this diet is spot on for me and others I know who follow it.
My daughter is b+ ve .she is suffering from eczema. I want to know if blood group and eczema is related to each other if yes how i can take care of her and please let me know what food to give her and what to avoid we r vegetarian
