Debunking the Blood Type Diet

by Moin Uddin Ahmed Tipu

The Blood Type Diet (AKA Eat Right 4 Your Type) claims there are certain foods and lifestyles better suited for different blood types. Is there any merit to this? And why do we have different types of blood in the first place?

Nobody evolved, dude. It's impossible without an Intelligent Being setting it into motion. But I believe God is more capable than that…which means He created everything within a fixed period of time…He didn't just send it spinning. Sorry, but I'm so sick of people talking about evolution like it's a fact. It's IRRATIONAL AND ILLOGICAL.

I’m a ten year vegan and type O negative. So are all my family, who have seen a lot of benefits from cutting out red meat.

Mr. KeepItReal March 23, 2020 - 7:11 PM

Your making claims you can’t substantiate.

HikerInPa M April 2, 2020 - 7:51 PM

And you are a expert in what….. Please stare your degrees!!!!! Otherwise shut up

HikerInPa M April 2, 2020 - 7:53 PM

YouTube should shut down channels like this. This guy has noooooo expertise in this field

'n erd April 12, 2020 - 5:51 PM

hmmm, I thought type O was the first blood type, then A evolved, then B than As started dating Bs and AB was born.

Shawn Johnson April 22, 2020 - 8:29 AM

Blood type diet is true! I shouldn't be eating meat.

Michael Kris April 27, 2020 - 3:54 AM

Where is the debunking?? You just repeat that it “doesn’t work” but you present no evidence. Maybe there is a lack of evidence on the other side… but you present absolutely nothing contrary to that belief system. Also, eating for my blood type A+ has changed my life. I can personally attest to the effectiveness of the diet. But, I guess that doesn’t mean anything from the scientific perspective?

Nick Latino May 8, 2020 - 9:01 PM

Your blood type does affect your diet. I'm blood type O+. And since eating less red meat, I've gotten reynaud's syndrome and bad gas. I've gone back to eating more red meat in hopes that those symptoms go away.

Ronald Gideon May 23, 2020 - 2:54 AM

No you shouldn't. Also I do not believe it is for dieting it is to simply eat the foods that are good for your body. To help in the way you feel and your energy levels etc.

Ronald Gideon May 23, 2020 - 2:56 AM

Simply like putting gas in your car. You use regular gas not diesel or your car would start to fail and not work as it should.

Pablos Rubenstein May 24, 2020 - 8:24 AM

Ive got the book. Its called "eat right for your blood type".
I have noticed may foods that cause me harm, and the foods in my blood type. I think it has a beneficial effect on how my body feels. I liked it and think its good.

Brenda Breslin July 6, 2020 - 9:00 PM

The Blood type diet, makes sense. Some people can't digest certain foods. Or have a severe allergic reaction to something.

Sarah Abiola July 28, 2020 - 2:16 PM

I did this to loose weight before going to Africa in 2011. I did it as a sceptical person but since I worked in a lab and have thyroid issues I would check my blood work every week…things were getting to normal. I went from 315 lbs on feb 2011 to 290 by may 2011. I would prefer it to be an intermittent life style change for to get healthy as long as you stick to your plan. It does work

anonymos 7 July 28, 2020 - 3:09 PM

It works .

Vagos V July 28, 2020 - 9:29 PM

There are unique blood types and there are specific foods that go better for each. Its exactly the same with the car engines
Stop libtardizing everything. People are NOT the same. Our evolution was influenced by the environmental counterparts our ancestors lived. Each human race has its pros and cons…!!!! ! ! !

JEx7hi3h August 17, 2020 - 7:02 AM

Chicken has blood type b agglutinating lectin.. therefore its bad for people with blood type b.

Alex Rimican September 9, 2020 - 5:09 PM

Saying that there’s no evidence, without giving any evidence himself, sound like ludicrous hypocrisy.

Trying to bring some fake knowledge here.👎

It's the reason why not everyone thrives on the exact same diet. People may argue that the diet itself has not been subjected to a rigorous double-blind studdy considered the gold standard for reasearch.. that might be true but the double blind studdy is a paradigm much better suited to a clean get-in get-out trial of a single therapy or intervention, like a drug or a specific medical procedure. The logistics of testing the theory of eating according to your blood type would be staggering thousands of patients would have to be enrolled their diets carefully regulated. Would people actually stick to tge prescribed diet? And even if they followed it to the letter, because it takes so long for health effects to develop in people, the experiment would have to be carried out for years. What would be required to test the diet a theory that involves hundreds of foods-times four one separate test for each blood type? If the lack of a larger-scale, double blind, placebo-controlled studdy of the blood type diet bothers you, you may also want to know that it is generally agreed that upwards of 25 percent of all pharmaceuticals lack similar proof.. You should also know that they actually did do lab tests with hundreds of different foods, lectins and anti agglutination protiens ect, and the effect those foods had on the different blood types and their effects on metabolism and digestion.. The science is on the website along with 30 years of ongoing reasearch that includes thousands of dieters who documented the levels of improvement they'd experienced from their perspective, supplemented and fortified by hard hand data like lab tests and physician reports from those same individuals. This isn't bs mate, there is definitely truth in it.

The only thing I learned from this, is that there's about as many blood types as there are genders, except the blood types actually exist.

GenZPhilosophy September 22, 2020 - 2:07 AM

I’ve been doing the blood type diet for a while and nothing changed with my health

sus2731 October 17, 2020 - 4:02 PM

Fast forward 7 years and 8 months in the future and we have Covid-19…and guess what?…..blood type seems to be important to know who would develop more serious symptoms…..

Actually I have found that eating for blood type O has worked for me tremendously

The society-approved carnivore's (typically white male) have a hard time digesting the fact that eating meat isn't always healthy :C

O ML June 9, 2021 - 10:58 AM

Very well done video. I loved this diet for many years even though I never lost weight, and destroy nicely my health following it. Finally I gave up.

Tamanako July 25, 2021 - 6:08 AM

Possible Correlations: blood type as % of total population:

Countries with the majority of their populations having a strong meat eating culture: Australia, Sth. Africa, most Latam countries (Argentina, Brasil, etc) all also have most of their populations as Group O.

Mediterranean countries (Spain, Italy, France, etc) have a balanced diet culture, meat+vegies. Most of their populations are more evenly balanced too in thier blood grouping composition O, A, B, AB

Mid-Asian countries who have a strong vegetarian or dairy culture also have most of their populations as Groups A, B and AB. Less of meat lover Group O vs the rest of the veggielover groups.

One could say there could be a strong correlation certainly and blood groupings may actually be driving the diet preferences of a larger population. Meat eating may work ok for some, vegetarian diets may work for others.

el-sig July 31, 2021 - 6:00 PM

This vid is terrible!
Did this guy even read up on any of this at all?! It seems all that he's going by is the fact that some scientists have criticised the theory. What about those who support it?

C Callender August 8, 2021 - 7:09 AM

His evidence that it doesn't work is even worse than D'Adamo's evidence that it does work. I am B blood type…and since I cut out chicken, corn and wheat…my joints don't hurt like they used to. So that's plenty of evidence for me.

B Perez August 23, 2021 - 8:15 AM

Joyce S December 4, 2021 - 9:24 PM

It is science based, that different bodies require different nutrients . Now a strict following of it? No… individual. Some feel better on vegetarian meals, and some have died or gotten very ill from it. Know your body, qnd know 1 formula is not for everyone.
