Blood Type Diet: Does It Work? | UCLA Center for Human Nutrition


One of the most popular diets that doesn’t work is the blood type diet Now blood types evolved in Human beings for various reasons over the history of man but it has absolutely nothing to do with diet It’s important if you’re going for a blood transfusion that your blood be carefully mMatched for type A, B, O or O+ whatever it happens to be. But this has nothing to do with diet. Now what this diet author did, he sold millions and millions of books was to kind of say– well the diet you need is the one at the time a particular blood type evolved during the evolution of man Well that’s total bogus. These diets don’t work Why was it so successful? Because this was the first attempt at personalized diets. People know that they have their own blood type, so they think– “Oh , well if I follow that diet for my blood type, I’m going to lose weight.” Well the fact of the matter is it’s not based on science and this is definitely a diet myth

    Has he even read the book? Has he tried the diet himself? I doubt it.
    The science of the blood type diet has to do with lectins (certain proteins found in many foods) and their selective reaction with antigens of the blood type. Depending on the specific food and the specific blood type, this reaction either slightly thickens (coagulates) the blood, slightly thins the blood, or has no effect on blood viscosity. This is not new. First noticed independently by William Boyd at the University of Boston and Karl O. Renkonen at the University of Finland, both of whom observed that extracts of certain plants coagulated one blood type but not another. Look it up.
    Dr. D'Adamo extended this research and tested various foods with various blood types. He carried on the research of his father, who observed in mountain spas that some people did not recover their health on a vegetarian diet. He asked why.
    Although the blood type diet does not work for everybody, it may work for as many as 75-80%, across all blood types. Amazon has more than 2500 reviews of "Eat Right 4 Your Type". More than 80% are four- and five-star. According to D'Adamo, of the people who self-reported their results to him, 77-80% used the blood type to advantage.
    Don't you think that the blood type has more significance than killing people with botched blood transfusions?
    "Dead doctors don't lie."
    Is this doc just ignorant, or was there another agenda?
    The real problem the blood type diet presents to some people is that it cannot be patented.

    Clearly no research was done by this guy. Lectin blood type specificity is littered throughout medical journals. The history of the blood groups has nothing to do with the specified foods for each blood group. Good god man. Is he a real doctor?

    I discovered blood type diet 2 mts ago and tried it, so easy and it works. 5 lbs of belly fat I just could not get rid of. I regularly exercise yoga and spinn classes and I ate healthy, but my belly fat keep me looking a like I was pregnant. Inches and wet off in 2 mts and my weight is consistent not egg fluctuating like it did before 134 to 138, consistent thy Ky 132.6 past week. Unbelievable, benefits on my joints, back and neck injury. Cut out chicken and everything according to my blood type B. It works.

    I have had a diagnosed history of stomach ulceritis and IBS for many years. Went to multiple doctors whom recommended various drugs and treatments that only managed symptoms. After several years; I learned about the blood type diet and started implementing it. As type A, I cut out all red meat but continue to eat Chicken, salmon and tuna along with the recommended fruits and veggies. The change in my health has been nothing short of a miracle. For over 5 years now, I take no medications. I have no ulcers today and no indications of IBS!

    With all due respect; you are wrong and I am living proof that the blood type diet works!

I eat the things that my body needs but let’s not just talk weight loss, let’s talk that I no longer get migraines (I would get at least 3 a week) my joints no longer hurt or inflamed, I dont have gas or heartburn anymore! I’m a blood type O we need to stay away from pork well there has been a couple times I’ve had pork in the last couple of months and each time my stomach swells I have gas and I feel so run down again! I only had to make a few changes so you can’t say that I lost weight because I started eating different! Try again and this time try it, you could stand to loose a few pounds!

These parrots repeat what they are told and see only what they are authorized as servants of the medical industry to see, their bound by these medical industries and by their greed and the sales of medication, actually most doctors prescribe medications in return for rewards from these drug companies, prescribing kids medications that ruin them, and many other cancerous products, in fact the same people that own the medical industries own the pesticide chemical industries and the food industries so they are expert at curing cancer etc and all our other sickness, As most of it comes from the food we eat contaminated with the pesticides created by the same scientists? they distribute narcotics through these lovely noble doctors? such a cheating industry but we trust them! we trust them because of their bright long hallways and shiny expensive machines and highly payed staff! they perform miracles of surgery and save so many lives but instead of being happy just helping the suffering? they became a mass profit parasite institution working to create patients rather than decrease them? like the leftwing government purposely increasing the welfare state to increase their own voting population, these people similarly help increase the Prozac taking population? the medical world is similarly crooked and this guys smile and white coat? white like the crooked preist? doesnt fool anyone, He's a glorified drug dealer who only adheres to the parasites framework and is here trying to get merit points? maybe win a holiday from the Prozac people .)

    Dr. Peter D'Adamo is not claiming his "diet" is a weight loss program. One still needs to find the balance between exercise and calories. Just because a food is listed as beneficial for one blood type, doesn't mean one should eat thousands of calories of it. D'Adamo's diet is more about reducing inflammation. Had I known about the blood type diet, I could have eliminated decades of migraine headaches, rashes, and joint aches. This UCLA bozo does not know what he is talking about.

    I used to roll my eyes at this diet but after suffering with so many ailments doing keto, high protein etc I felt weighed down, depressed and bed ridden. Docs wanted to put me on antidepressants and blood pressure meds. My friend thrived with keto and was building muscles so I felt confused. Eventually it came out I was blood type A and she was O. I then switched to the A diet and my body responded immediately. Lost weight, I'm energetic, I have my life back, blood pressure normal. When my type O friend tries my diet, she can't function at all. She hates it and I hate her diet. Seems like those with European descent must follow an agrarian diet. I was unfortunately born in a hot country but I thrive in cooler weather. There must be something to this!

    the way i understand blood type diet is that it has nothing to do with weight loss its just eating the right food that caters to you because of your blood type and by doing that it keeps certain diseases away and brings your body back into better alignment. if you lose a ton of weight while doing it even better.. im O+ and suffer from really bad gastric but ive not used the gastric medication for almost two weeks now since ive stopped eating foods that have inflammatory properties… cutting out wheat, corn, melons and such, looks innocent but it works for me… and you cant say it doesn't work when there are millions of people testifying that it does and it has.. its just not a quick fix because it can take up to a year for your body to get in the right state, that 12 months of you eating the right foods before you are 100%… not two weeks or 1 month…

    My almost 101 year old grandmother is A+ and never ate a stringent diet in her life, just ate in moderation and never smoked and rarely drank. A follow up book called “The Answer is in Your Blood Type” stated the average age of death for a type A was 62, but 86 for type O. Because of type O’s extroversion and lack of a filter, it’s assumed they live the longest. My O+ dad, a very angry and bitter person, died at 66 from oral cancer from heavy smoking and drinking and my A+ mom looks great at 75 and has the social energy of a 12 year old and a lifelong nonsmoker. Just high blood pressure from a wound-up personality.

    GUESS WHAT MR. IMPRESSIVE UCLA , TRUSTED ,EXPERT GENIUS GUY, 20 Years ago, The Blood type diet SAVED MY LIFE. I am a TYPE O NON SECRETOR GATHERER…Little did I know it, but my whole life I was being egregiously violated and poisoned ( And No, I am not Not Celiac) mostly by the lectins in Wheat and other bad food lectins as well that were traditionally and routinely in my diet. At Age 43 , I was a FAT. SICK, MISERABLE, METABOLICALLY INSUFFICIENT DYSFUNCTIONAL , PRE DIABETIC / DIABETIC SLOB… I HAD TRIED EVERYTHING INCLUDING THE ADVICE OF AT LEAST 17 DIFFERENT MEDICAL DOCTORS AND EVEN A 10 DAY STINT AT THE FAMED, HALLOWED MAYO CLINIC… NO ONE WAS ABLE TO HELP ME …NOTHING THEY OFFERED UP AS A SOLUTION WORKED FOR ME…. UNTIL I FOUND THE BLOOD TYPE DIET OF DR. PETER J. D'ADAMO … UPON EMBARKING ON DR. D'ADAMO'S PROGRAM, IN 4 MONTHS TIME OF STRICTLY ADHERING TO THE BLOOD TYPE DIET, I , (WITHOUT EFFORT I MIGHT ADD ) …LOST 70 LBS. OF DISGUSTING FAT AND GAINED BACK 15 LBS. OF LEAN MUSCLE…. MOST IMPORTANTLY , EACH AND EVERY ILLNESS AND SICKNESS SYMPTOM THAT WAS IN MY REPERTOIRE THAT HAD HAUNTED AND PLAGUED ME FOR YEARS SIMPLY VANISHED…POOF!!! GONE!!! A LA HARRY HOUDINI!!! SO, IN CLOSING, AS I SEE IT, ( AND MANY, MANY OTHERS SEE IT AS WELL) YOU ARE DOING THE WORLD A GREAT DISSERVICE BY ESPOUSING YOUR ERRONEOUS BELIEFS AND SHADILY VEILED UNTRUTHS. I AM NOW 63 YEARS OLD AND AMONG OTHER THINGS, I CAN STILL SMASH A BASEBALL OVER 400 FEET WITH A WOOD BAT… I AM ROCKIN AND ROLLIN AND HAVE NEVER FELT BETTER IN MY LIFE … IN NO PART ATTRIBUTABLE TO YOU AND YOUR KIND, …BUT ALL THANKS AND ACCOLADES ARE GIVEN TO THE TRUE GENIUS OF ONLY ONE MAN .,,, I OWE IT ALL TO DR. PETER J. D;ADAMO… A TRUE HERO IN THIS WORLD!!! PS, THE REASON FOR THE CAPS!!! I AM HONKED OFF WHEN SO CALLED PUNDITS LIKE YOURSELF MISREPRESENT THE TRUTH… AND THE UNKNOWING PUBLIC WHO HAVE NOT FOUND THE KEY TO THE DOOR TO UNLOCK GOOD HEALTH BELIEVE IN WHAT YOU SAY! PLEASE DO US ALL A FAVOR AND LEARN THE SCIENCE … IT REALLY WORKS…

    A couple of other things Dr. Dave Heber … Do you think we're all stupid? When I entered Peter D'Adamo's name in my search on Youtube, the very first thing to come up is you????? .. I was like WTF???? is this? The Very first thing to come up was You Ranking down on the blood type diet without a single shred of evidence to back up your blatant lies… Just because you're some supposed big shot Dr. at UCLA… That means absolutely nothing to me or most other folks who are searching for the truth… It is Utterly ridiculous… It is an Obvious and transparent attempt to cover up, (obvious to me anyway) to disparage, to berate, to mock, to besmirch, to discredit, etc. etc. a tried and true vehicle of good health science for the masses to achieve better health and more than likely allowing themselves to be removed from the world of prescription pharmaceuticals… PS, It looks to me like you could benefit yourself by pulling away from the Pasta Bowl!!! If your physique is supposed to represent a model of Good Health, COUNT ME OUT!!!

    I had bouts of bronchitis and walking pneumonia for 13 years. The doctors always prescribed antibiotics and sterrhoids and told me I had weak lungs. The antibiotics destroyed my gut lining and I deal with this issue to this day. I found D'Adamo's Blood Type Book in Jan 2003. I immediately followed his diet, strictly, and never have had another bout of bronchitis or walking pneumonia. Say whatever you want but something in that diet fixed my problems when conventional medicine completely failed me.

    Not true. My mother in law eats for her blood type and lost weight and lowered her blood pressure. You have no idea what your talking about. Oh and by the way there is no such thing as evolution. Have a nice day.

    No evidence. Don't quote the 2014 study of 1455 participants either. That study is false. (1) competing interests (funded by Nutrigenomix Inc) (2) the participants didn't even follow the diet nor did their food questionnaire contain the same foods listed in the book

    A few years ago I started following the blood type diet and not only did I become a healthier weight, my digestion and skin became better.
