    I attended a session where a naturopathy doctor gave a talk. She mentioned this diet during her presentation.
    She had decided to try it. I don't remember the breakdown of each blood type, but hers suggested she eat mainly vegetarian, beans, grains, veggies, etc. She followed it to a t and had great results. She lost weight, her skin glowed, etc. During a conversation with her mother, she discovered that she was mistaken about her blood type. Here she was supposed to be eating the opposite, heavy on the meat, lower on grains and dairy.

    Bottom line, as most have already pointed out, there is no real basis for this diet.

    The most obvious problem is when they try to tie in blood type with its evolutionary history, they had their history wrong(at least last I checked). They don't know for sure which blood type emerged at which time and where, and without knowing that for certain, the diet falls apart.

    My sister-in-law gave me this book a few years ago. I didn't follow it. It didn't seem scientific at all. Plus, it would be a pain to cook in my household since we have more than one blood type in the family.

    Type A blood: A meat-free diet based on fruits and vegetables, beans and legumes, and whole grains -- ideally, organic and fresh, because D'Adamo says people with type A blood have a sensitive immune system.

    Yeah right, I tried a vegan diet. Not only did I feel miserable and bloated, I also gained from it. Next to that I got a gluten intolerance, so no grains for me either! But fact is I do have a sensitive immune system and should eat only fresh food, can't have much of the processed foods. I don't know, I 'm not sure if this would work for everyone, guess just like with every other diet...

    A few years back, my mom told me about this diet, and I'd shrugged it off as unscientific, which it is.

    The really funny thing is that since I've started moving towards more whole foods, higher quality meats, eating more red meats, more fat and fewer carbs, etc, I've been feeling fantastic. This is apparently how someone with an O blood type is supposed to eat. Because we're cavemen or something ridiculous.

    I'm only saying this because it's funny. This is not evidence for the blood type diet. It's just a coincidence. There is no science to support it.

    How funny. I am Type A and happened to grow up eating like this without knowing about this diet. I was so strong, felt awesome, and looked dynamite. Then I got married. Making two types of meals became a PITA. So here I am on MFP to lose weight and bring sexy back. I miss the first 30 years of being so healthy!!

    just for the record, it is NOT my plan to use this system to lose weight, i will still be using calorie tracking to that end, I am talking about cutting out a few items, like dairy, and red meat, on a short term basis. I have recently been noticing that for myself, I have been getting sick more than usual the last little while, and the main idea that I am working on from this dietary regiment is to strengthen my immune system. we don't eat a lot of processed stuff in my household anyway, so no big deal on that score. the main thing will be the dairy, and red meat since they are connected to processes within the body to weaken immune response. I am a born and raised meat-n-potatoes guy, but am becoming more and more aware of how the htings I eat affect my health. I will keep posting to this thread about my progress(or lack thereof) while I am following the system, and you can either follow it, or not, whatever. Everyone of us needs to find our own path, and the foods that work best for us. Maybe I am currently eating in a way that isn't what is best for me, maybe not, but without checking, i'll never know, and for 12 weeks, it can't hurt.......not like supersize me!

    just an afterthought for all the people who are claiming "no scientific support" anecdotal evidence of results from a practicing naturopath is a starting point....the accumulation of more data can happen when there is enough anecdotal evidence to support a FUNDED scientific inquiry. Some of the most important discoveries humans have ever made started out as the casual observations of someone in the field, and were met with skepticism in the early going.....just sayin

    Eating for your blood type is just as valid as eating for your hair colour.

    I have the book and tried it for three weeks. I did lose some and felt better, but had

    A hard time not drinking coffee and cutting mostly carbs. I think it's good for a jump start, but hard long term.

    Type A= no meat. No thank you.

    No meat? Native Americans were only type A before settlers arrived. The 'no meat' thing wouldn't have worked out very well for hunters and fishermen, lol.

    there's no scientific basis in it. just eat at a calorie deficit and you'll lose weight.

    blood groups come from having specific antigens on the red blood cells. That doesn't change how the body processes food. It doesn't correlate with any actual factors that affect how the body processes foods (e.g. tendency towards diabetes). I'd be interested in which blood type they say should eat dairy, because only people who are descended from traditionally dairy farming/herding populations can digest lactose. I'm not aware of any correlation between blood group and whether someone's ancestors were dairy farmer/herders or not. If there is then it's due to genetic drift and nothing to do with actual blood type. I'd imagine that there are huge numbers of people who, according to the blood type diet should eat dairy products, yet have not inherited the ability to digest lactose.


    Not all lactose intolerance is the same. There are actually three different types:

    1)Primary lactase deficiency – this is the most common form. If you have this it is simply because you are not the descendant of cattle herders.

    2)Secondary, acquired, or transient lactase deficiency – in this case, you may be a descendant of a cattle herder but your ability to secrete lactase has been hampered due to a small intestine injury – possibly caused by acute gastroenteritis, diarrhea, chemotherapy, intestinal parasites or other environmental causes.

    3)Congenital lactase deficiency – is rare. It is an autosomal recessive genetic disorder that prevents lactase production from birth which prevents babies from digesting breast milk. It is most common in Finland.

    So technically if you breastfed without any problems, your relatives have a history of drinking milk, and you haven’t suffered from any severe intestinal injury then you should be capable of digesting dairy products. But many people aren’t. And many others become less tolerant as they get older.

    I read the book. It did nothing for weight loss, it did, however convince me to start drinking coffee in my thirties and for that I am forever grateful! (Aka addicted and I love it!)

    Hey, I'm only new to MFP really but I read through and felt the need to respond. I would have seriously had my doubts myself if I had not chosen to focus on a plan to eat for Blood type myself. I didn't do this to specifically loose weight. My partner has gained 2 Kidney transplants in his life and may not get a third. We discovered our blood type is the same and we may be compatible meaning that I may be lucky enough to have him in my life longer.

    Oddly 6 months ago, we both got sick and decided we didn't feel like eating meat anymore which is not like me at all. While doing that we chose to take a look at following guidelines for eating for our Blood type and connected with Asian friends who are knowledgeable with cooking to keep your blood healthy and Chinese medicine.

    3 weeks ago my partner went into the hospital to see his specialist, the doctor was shocked at his results. My partners first problems occurred when he was 11years old and had his first transplant at 13. His doctor said to him "My gosh I don't know what you are doing but your bloods have never looked this great...Keep doing exactly what you are doing!".

    I don't know if you are looking at this for health or to slim down and I didn't use a book just researched online and received help from my friends. We know we still have a lot of weight to loose but have been loosing slowly. We didn't do this to loose weight though. Now that I have recipes regularly in our daily diet, I'm focusing on loosing weight by cal count and fitness.

    Hope that helps x

    The story of the naturopath was just for entertainment, I thought it was amusing but that is not what I based the "no scientific support" on. I have actually read various breakdowns how inaccurate some of the science behind the blood types is (as someone mentioned about Native Americans and type A blood)
    If you want to do it, go ahead, but why ask if you don't want to hear opinions.

    All in all, none of the diets are particularly bad ones. I suspect that many people would benefit from eating any of them if switchng from your SAD. I dont' believe that benefit has to do with blood type.

    People eat processed food and live to be a hundred- the ones who maintain a normal weight, that is.

    If processed foods were bad for you, the FDA would get rid of the bad ones quickly.

    Don't we wish. It's past time to get rid of nitrates.

    Source? Just asking because I thought it was Type O and I'm curious. PubMed says O, though.
