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?
The 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).

I just found out about this blood type diet and is so eager to try it. Although I have a gym membership and has been vegetarian for almost 10 years. sometimes i feel i gain weight just by drinking water lol.
i want to lose 15-20 lbs in d next 2 months. please wish me luck.
I think what contributes to my weight gain is my constant alcohol comsumption.
I have tried all different diets that had work but i guess the older you get the slower your metabolic system slows down.
my friend told me about genuine health abs plus.try at your our risk it was only a suggestion by a friend that am yet to try.
And remember if you want to start a diet regime do a detox first with a colon cleanse, watch what you eat and exercise.
good luck and i will keep y’all posted on my progess
My mother-in-law recommended “Eat Right for your Blood Type” to me after my pregnancy. I was struggling trying to lose my last 10lb and having a furious bout will allergies. I am O-Positive. Before reading I thought my diet was pretty good. I ate a lot of vegetable, fruit, whole wheat bread and pasta’s. After reading the book I found I was not doing such a good job. So, I slowly started to eliminate gluten out of my diet. Face it, if you’ve been eating the wrong things for a long time and your condition is not life threatening it takes a lot of discipline to give up the things you enjoy. Needless to say, I am Gluten free. I don’t take allergy shots anymore, and I haven’t had a cold in a year and I lost my 10lbs. I was never able to run without sucking on an inhaler. I am proud to say I ran my first 2 miles inhaler free this year. I always get a cold once a year and I haven’t even had a sign of a cold in a year. My husband, poor thing, is also O positive and has to abide by this lifestyle change as well. He commented to me a few months ago because I caught him eating some Doritos, “That there is nothing wrong with these, they don’t affect me”. My comment back was do you realize that since we have been eating by the “Eat Right for your Blood Type Diet” that you haven’t had a cold or even felt like you were coming down with something this whole year.” He had to stop and think a minute, and then agreed that I was right. He always gets anyway where from 2 to three colds a I told him it is not the immediate effect. It the lectins that Doritos leave behind that make us susceptible to colds, virus, bacteria, and eventually disease. I talk about the Gluten because for me that was the hardest for me to give up and it made such a huge difference. The other avoids for O positive wasn’t hard for me because most I didn’t like anyway and the others if I had it was very seldom or it was no big deal. I have to thank my mother-in-law for recommending it, and thank Dr Peter D’Adamo for an awesome way of life. I do have one question though. I just recently watched “Knife and Fork” a documentary about the western diet. According to doctors and scientist they recommended a wholefood diet for all Americans. Is it good for O Blood Types to have a wholefoods diet? According to the show the amount of protein and amino acids we receive in fruit and vegetables are sufficient for the body without consuming meat. For all the non-believer you need to start believing. It works!!! Most of your aliments are because of your diet.
type o+ currently tryin 2 recover from severe case of c diff & colitis w/ bloody diarreha after antibiotic s. diarreha continues but is black tarry. am afraid of anything I eat now as bloating and much heat n gut. living on h2o, grape juice, and baked potatos. have cut out all diary. i would greatly appreciate more sample diets. am 62 yo w/f. also have had IBS for many yrs.
I’ve been looking for the best way to loose weight and stay healthy. I sincerely think this will work because i’ve tried vigorous exercises but it didnt work. I’ll keep to this because i’m blood type A+
I have been reading as much as I can for the last week and have been on the eat for your type diet (type O) for about 5 days now. I haven’t been good all the time, nor sticking to the diet guidelines perfectly, but I have tried quite hard. I was wondering if it is wrong to have a small bowl of cooked rice with a teaspoon of butter in for breakfast?? I have played around with combinations of different foods and avoiding the not allowed foods. I love the tuna salad I just had for lunch with baby spinach, watercress and rocket, feta cheese crumbled, rosa tomatoes, chopped fresh onion, tuna fish and a generous splash of olive oil, a little salt. Absolutely lovely. I had a banana for something sweet too. I like my food and feel grumpy if I feel like I’m going to starve. Ecstatic that red meat is on my list. Just need some help putting more meal options together. I love beetroot, but am concerned that the bottle variety is soaked in vinegar – and vinegar is forbidden. It’s a learning curve, but I am happy to learn more, feel better and loose a few unwanted kilograms.
My girlfriend and I have been trying this for the last 3 weeks. I’m type O and she is A, so we have to be a little watchful on what we plan for menus, but it has been good. I’ve lost a few pounds and she has lost more.
We both are more energetic and have been working out as well as contuinuing our evening walks.
Hey, I’m 29 years I’m suffer with headache, my blood type is A+. I want to loss my weight, I want to use diet system Please help me. what kind of food I eat.
I just found out that I’m type A, and I just found out about the Diet thing, and I’m not afraid to try it. I see that all the things I’m not suppose to eat, actually, has been effecting my health. So, sometime this up coming weekend, my whole family and I are getting food for our blood type diet, and will be trying it for the next 30 days. I think you shouldn’t be afraid, or just say something doesn’t work with out trying it.. If something you think works for you, than keep it, and take out all the other stuff… You should want to be healthy, and happy. So try something new, and see how your body likes it.
I produce to much calcuim in my body i’m a type O positve what is it that i’m eating that produces to much calcuim could it be to much red meat? I’m 42 years old
I believe this can work because im actually found out that im lactose and tolerant (cant have milk or certain cheeses)because im A Positive. The only problem is i love meat but i guess i can become vegeterian. I tried once….. very hard.
i have been overweight most of my life.
i’m going to try this O type Diet.
I think the blood type diet works, i am type A and I tried this method and it really made me feel. much better.
thank you for all that information that you all have given to me i have spent so much money on me being sick i think if i do the diet i will be fine. rachel
i am o positive and is very much over weight i do not eat every and anything i do believe in eating for your blood type.
Mary Daly. I’m also blood group O and i would highly recommend this diet for the symptoms you have. I also had sinus problems and depression and I found that by changing what I ate, I completely eliminated all sinus problems I had and my depression lifted dramatically especially when I started exercising. It may sound drastic but what D’Adamo suggests about eliminating dairy and wheat really worked for me. I also bersitis, a joint problem in my hips, and the diet really reduced the pain. It may sound obvious but I really quickly discovered that what I fed my body had a direct influence on how it performed and it completely changed my mood. If your getting dizziness I would also suggest getting your iron levels tested as it’s a problem most women experience especially if your blood group O. The high intake of protein in this diet would definitely benefit that. I got an iron transfusion a few years ago to deal with my low iron levels and instantly had more energy and my dizziness was gone, especially right after I stood up. I’m O negative and I completely changed my lifestyle by following this diet. You’ll definitely see an improvement in your sinus problems by eliminating dairy from your diet. Give it go!! I can guarantee that by changing what you eat you’ll notice dramatic changes in your body and after even a week you’ll begin to feel empowered to take further steps to improve your health.
This is ridiculous. I’m type A negative and cannot survive without milk and cheese. I put cheese on everything and love to drink milk. I haven’t missed a day of work in over 4 years, so obviously I’m healthy. I will say that I eat very little meat and love raw vegetables. But the problems with dairy products do not seem to be an issue for me!
Hi I’m 32 years I’m suffer with headache, sinus, itching of eyes, heartburn the doctor once said I have a migrane, alegic to dust I must stop using dairy products my blood tyope is A+. Is it because of the food I ate.
I suffer from very painful knees, hearturn, sinus, dizziness and depression. I am blood group O positive. Is there a hope for me with a paricular diet??
I’m a type A (42 YO male), and for the last week I have been on a vegetarian diet with almost no dairy. The change has been quite amazing. When I eat now, instead of feeling a little sleepy afterwards, it actually feels like I had an energy drink. I don’t get cold as easily, and I seem to be in a better mood! I may never eat meat again!
Good day,
I just want to find out something regarding the info for the bloodgroup A. I am allergic to fish and diary products. What can I replace with those that I am allergic to.
Try a course of probiotics (friendly gut bacteria) or prehaps you have low stomach acid therefore your body wouldn’t be digesting proteins very effeciently. Keep a diet diary for a couple of days and make a note of when you have a problem, maybe thst would help identify the offending food/s. Sugar can give you flatulence as can intolerances to diary or wheat.
Ok, I dont really need to lose weight but something I’m eating is giving me GAS that smells… I dont know exactly what it is I take enzyme pills that help I’m 56 years old and wonder if I’m eating wrong foods. I know if I eat apples or pinapple I dont have this problem at all so I’m guessing my body doesnt produce enough enzymes on it’s own any tips?
