I gave this a 4 because it fits the book title, and it's not fair to give it a 3 when I did not read the other blood types all the way through. I'm sure they're just fine. My type O diet is interesting. So, I need to eat lean red meat and anything else I can hunt down and kill, because it's the primitive homo sapiens blood type. Great. However I am also a cancer survivor who gave up red meat. And what meat recommended! Lamb, venison, liver, veal, heart, mutton, buffalo - all stuff I wouldn't have put down my neck when I did eat meat. Rabbits? Baby calves and baby sheep? I'm good on the no dairy, but have you ever seen kelp in the produce aisle? If I need kelp I can roll about 22 miles away/44 round trip and go to Whole Foods or Trader Joe's, but my carbon footprint would get a bunion. I glanced at the other types. How come mine is the most expensive and exotic? Primitive diet. Not sure there's any meat around here the owners would be happy to have me wrestle to the ground and butcher. And it would probably wreck my pedicure. I'm also over 60. My blood type O requires high-intensity physical activity (the equivalent of running down that baby buffalo, I guess). I can choose between aerobics 3-4X a week for an hour each, stair climbing (same), martial arts, calisthenics, roller skating, weight training. The author offers the heart rate mathematics. I can almost do the math, but I can't do the time. So as Captain Barbossa says, they're more guidelines. Type Os were the epitome of focus, drive, and self-preservation; hardy and strong. And then, as if all this wasn't painful enough, the example of a fine type O is Ronald Reagan. If I see that name in any other context any time soon, I'm going to go primitive, all right, providing Cro-Magnon woman had a rich profane vocabulary in her fur backpack.

The hypothesis is false. Logically the theory of this book did not make sense to me. I also could not find any scientific argument for this diet either, in fact, I found evidence claiming this diet is not valid. Read here. http://news.utoronto.ca/popular-diet-... Anytime your switch your diet and/or exclude a food group, your body will change. The Eat Right diet excludes food selections. The book maintain "O" blood types become healthier on a high protein, low carb but makes no mention of how detrimental animal fats are to heart health and blood pressure as well as colon health. Additionally, I know O blood types who cannot digest red meat and become ill. Since I'm allergic to dairy, all but one of the four diets apply to me, A, and this is not my blood type. It was an interesting read but the science and practice is faulty. Eat a well-balanced, healthy diet, get plenty of rest and exercise, laugh and love a lot. This is the key to a long and healthy life.

This book was amazing for me as it replicated the results of my RAST blood test for food allergy. For instance oranges were killing me and Dr. D'Adamo says that Blood Type O should not eat oranges. That is just one example. I am allergic to wheat too but addicted to it. It contains something that is a pain killer and I forget at the moment what it is but it also causes arthritis as in Rheumatoid Arthritis. Wheat is super bad for me but when I am off it then I dream about it and crave it. But I keep trying. In fact most all grains are very bad for me and there are many veggies that I can't eat. My allergist told me never to eat tomatoes. Most people should not eat tomatoes as they contain something that causes red blood cells to agglutinate. You don't want your red blood cells sticking together as this can cause a stroke.

He says that I am a meat eater and he is right. I do try to cut back on the red meat as my iron level is very high but it is an intense craving also. I often eat a hamburger with no bun. It tastes so much better without the bun!

Right now I am trying to do the KETO diet and there is nothing about it in this book but the ideas are similar. If you feel bad I recommend reading this book and giving it a try. I refer to it often.

Super interesting theory. Humans started off with O blood type and were meat eating/hunting and foraging, then moved north from Africa and started farming to birth A blood type, agrarian. A type is more vegetarian and fit for more social structure. Then B blood type came about after and moved out east, India and such. Then AB blood type is the most recent. He did a lot of studies with blood and interactions with food compounds and based a lot off that. I can't remember how much was actual human applied, which is more important to me, but also hard to account for ALL the factors that go into assimilation of food. So, supposedly, O type is more meat eating, A type is generally vegetarian, and B type is the only one that handles dairy that well. AB type obviously has a mix. He really breaks it down to every food, which is pretty intense to narrow that down to me. I think it's hard though, because I think some is genetic/race, some could be blood type, some is environmental, some is locality, and some could just be straight up human adaptability, which is supposedly the cause of the blood type shifts to start with. Interestingly, a lot of the guidelines for A blood type (myself) were mostly right on with what my diet and likes/dislikes already were.

I don't usually like reading fad diet books but this one is totally unique. It lists foods that react badly in your system depending on what blood type you have. Seeing that I suffer from indigestion regularly I thought I'd have a look. Apparantly some of the foods that I eat nearly everyday are ones that I should avoid so I'm a bit dissapointed but hopefull. I will definately give it a go as I eat very healthily but still feel slugish and bloated sometimes. The reason why I gave it five stars is that when at the back it listed all the ailments that certain blood types are more suseptible to, according to me they are all correct. That can't just be a coincidence as it applies to my sister too as she has a different blood type. Good food for thought.

Wow! I believe this makes sense, but I think it would be very hard to stick to. I am O+ (the meat eater blood type) and I have been a vegetarian for almost 25 years! But I have also suffered from migraines for about 25 years(which also correlates with hormones changes) but still, it really makes me wonder? I may just have to go eat some steak....GROSS!

This book has changed my life. As a way to try to drop pounds, I'm implementing its strategy and giving up many foods I love that inhibit weight loss for type B blood type like me: corn, chicken, tomatoes, lobster, shrimp, clams, crab and anything with wheat in it. The book's premise is that, whatever your blood type, there are certain foods that are highly beneficial in digestion, some that are neutral and others that are toxic. I'm left with most fruits, vegetables, white fish and dairy products as good for me. Two weeks into the plan, I'm feeling good.

The only problem with the book is that many of the foods that are good for people (for instance in my case lamb, rabbit, venison, mackerel, sturgeon) aren't exactly stocked in the grocery cases). Also, even health food stores don't carry many of the recommended beneficial cereals, breads, grains, pasta and spices.

I understand what the author is saying but, for me, this just didn't ring true. The foods that are supposed to be the very worst for my blood type are some of my favorites and have never given me a lick of trouble.

Or it might be that I am on the cusp of becoming fully vegetarian that doesn't have my mind open to this.

I first read this book in 2000 and I read it often, even now to remind Me of what food works for me and what doesn't. My blood type is A+ and I became a vegetarian 20 years ago and I've been an Vegan for over 10 years now. I've never been on a diet and I don't see this book in that category.

I have always recommended this book to friends and I recommend it to anyone who has problems with losing weight or not even that, but who is always sick or never feels well especially after eating.

Give it a try, what have you got to lose.

You are what you eat and if you don't feel right after eating certain foods you shouldn't ignore it.

Fascinating take on lectins and how they affect the body based on blood type and thus trigger different immune responses and disease processes. I felt like it rang true for me and my experiences and would be interested to see how I’d feel following these general guidelines. It’s not to put people in a box but rather to help navigate different health issues.

This is interesting and I'm giving the diet a 4-6 week trial to see if certain health issues improve.

I have been reading bits and pieces of this book because it was recommended, many of the foods discouraged for my blood type are foods that I already knew bothered me, and I had already tried another diet which helped me lose weight but didn't help lower cholesterol. I thought maybe this diet would help with that. However, I never bought the history of the blood types as explained in the book, and I have finally had time to research the whole lectin idea, that certain foods caused cell clumping in people based on their blood types. When I got to this section of the book, it really bothered me that the author reported that the general public would not be able replicate his seemly simple tests on food lectins with blood or be able to accurately read the results of such tests if they tried. That seems pretty fishy to me. Why could Mr. D'Adamo see something, but no one else would be able to see it properly? I've been reading as many articles as I could find about this, and it seems like no other dietitians or scientists have been able to replicate his research either. So I am going to wrap up reading the book. I give it 3 stars as I haven't read the whole book nor even tried the diet so it doesn't seem fair to rate it too low. I take from it encouragement to eat a more varied diet as following my recommended food list to some degree has gotten me to eat some foods that I don't often eat.

This theory was overthrown quite some time ago.. plus the research I made myself also proves it's wrong. Like the "fact" that supposedly all B type people tolerate lactose. I for one seem to have no problem with it, but my nephew can barely eat a a chocolate bar. The only reason I won't give this 1 star is because non of those diets will harm You.

I was mesmerised by the idea at first when I saw that most of these claims are aligning with myself and my girlfriend. I checked this with few of my friends and one of them found it to be almost EXACTLY OPPOSITE of what he tolerates, has allergy for etc.

All in all,
Wouldn't THAT be convinient - to have a list of foods that are genetically good/bad specifically for You. I'm sorry to say, but Bollocks! No such list can be made at that time.

Rated it five because it somehow helped me... I don’t know for others but most of the things explained made sense to me... like for example, there are food that I naturally hated eating (way before I even found and read this book) only because every time I eat it, I notice that it upsets my stomach,make me feel extremely bloated or sluggish etc.. so I avoid them as much as possible. Same thing with food that are a favourite of mine, not sure why they’re my favourite but all of it are listed on my blood type’s highly beneficial and the ones I hated are the ones I need to avoid.. (checked my husband’s and it’s the same) so no wonder🤔... I love this book! I highly recommend it!

Found this very interesting. I'm not 100% sure it's all correct, but I followed it for a few months and felt great! Lost a little weight too, without even trying. I just had a hard time avoiding some of my favorite foods since they weren't on my beneficial or neutral list. The idea behind the diet is fascinating. I'm type A, and I was amazed at how much of the advised exercise and common health problems truly fit me! It seemed worthwhile to try it. It's been several years since I read it and put it into practice. I keep thinking I need to pick it up again. Now they even have an app to help with the diet!

Interesting read. I have read a number of diet books and haven't read anything that had to deal with my blood type. I gave it a whirl and will say that I feel so much better and have lost weight while eating according to my recommended eating list. I think that the book is well written and well researched.

Great book that outlines various examples of blood type diets as well as different behavioural patterns of those who have specific blood types. It could do with more blood type examples but it is only an information book rather than a list of everything you may want to know about your specific blood type but regardless very informative and interesting to read.

4 Blood Types, 4 Diets, Eat Right for Your Type by Dr. Peter D'Adamo is a groundbreaking study of how understanding blood type and eating according to the specific needs underscored can provide a roadmap that can maximize the health of the body and support longevity. Each blood type has a specific chemical make up. Blood types, or O, A, B. or AB have specific requirements that allow the body to operate in an optimal fashion. The book provides food suggestions for each type, including teas, spices and condiments that can help maintain a healthy weight. It also discusses which vitamins and supplements to emphasize or avoid, what exercise is appropriate for each type and how to recognize the impact of stress on the body. Dr. D'Adamo is a well-known naturopathic doctor, researcher and lecturer. The correct diet according to blood type can maximize health, reduce cravings and ward off disease.

I found the book fascinating! Especially all the information on how blood types developed. The fact that it seems most people, including doctors, think this is all nonsense or at best, just not true.....doesn't surprise me as that's the way with all information. I spent time reading lots of the reviews and it seems that IF the diet recommendations are liked by the reviewer.....then it's okay. But if the diet doesn't meet with their approval.....then it's not okay. Ha.

Since I'm Blood type A, and I prefer to eat grains and vegetables over too much meat, sure I agreed with it. And my husband is O and he prefers meat.. My my!

Bottom line, anybody with chronic health problems should give any diet changes a try. My husband was deathly ill for a long time . Finally found out he had Celiac Disease. Quit all gluten products. Healed immediately!

I find the anthropological basis of blood types and proposed correlation between the optimum diet for a given blood type based on its evolution and good health and elimination of inflammation. Interestingly, the foods listed that I, as a type O should avoid, are foods that I either don't much care about or are foods my naturopath already has told me to avoid (in my case sugar, alcohol, wheat, other grains). She recommended I read this book some years ago. I recommend this book as part of your library as you work to maintain good health, which usually helps stabilize hormone balance and mood. I wish there had been more complete scientific references in the book.

Interesting health perspective. I've been intentional over the years at paying attention to how my body feels after eating so it was a pleasant surprise that a lot of the foods I've eliminated or have never cared for are listed as items to avoid. On the other hand there are a few foods that I really love and to me are healthy that are suggestions to stay away from. I don't think I'll be totally avoiding them just from this book but I'm curious to look more into the science of why and if needed act accordingly.

When I think about my health, I really try to view it as an overall picture. It's not just about what I eat, what time I eat it, or how many calories I burn in a day. I like to know how the foods I choose to eat affect my body. This book presented me with information that hadn't occurred to me. I found the information easy to understand and I appreciate that this book isn't about strict dieting or really dieting at all (or at least to me) but more about ways to choose foods that will benefit you more based on your blood type.

Would highly recommend.
