Anyone heard of the blood type diet? What's your take?

Skepdic has a takedown:

In short: the author has never performed studies to test his theories, and his theories are built upon shoddy information.

This^^^^ No case study = fail.

It's hogwash. Almost any "diet" works if you stick with it. I choose to eat the things I like, in normal portions, in a way that I can sustain for the rest of my life. What happens when you go off those diets? Have you learned anything about the proper way to eat? Can you maintain it for the rest of your life?

My mom swears by it, and constantly tells me since I'm an AB I need to avoid chicken and oranges. Two of my favorite foods, um EFF that noise. She has been avoiding certain foods for years just because of this BS. She is still 50 lbs overweight.

There's your anecdote.

I'm sorry, I didn't watch Twilight, but I bet there is a better way with just a eating above your BMI and below your TDEE.

I prefer the DropTheDeuce diet...if it sinks, you're on target....

Is bood high or low in calories?

In all seriousness if you don't want to don't unless certain foods are giving you problems.
I'm blessed with A negative blood and my doctor has mentions that is the big contributing factor in why beef gives my stomach horrendous pains. Mostly because he can't determine any other reason, and he's seen others with A negative blood have similar issues. I've cut beef from my diet and my stomach feels a lot better.

sorry that was kind of irrelevant. /shrug I think my point was sometimes blood can effect digestion or something to that effect. idk.

It's like a horoscope for nutrition.

Awesome.
My mom tried this diet back in the '80's. After that, she tried a diet where she filtered everything through red light first.

Like just passed it by the light or literally ate under the red light? Because there is scientific evidence that changing perception of color of food impacts rates and amounts of foods eaten.

Junk science.

Can't use the word science !! It's as unscientific as you can get.

Taking a consensus from the group here is proof positive there's money to made for just about anything you can think of without actually having to back up those claims, lets face it, a broken watch is right twice a day

I think it's ridiculous to choose diet based on blood type.

According to that, I should eat plenty of meat and avoid grains.. but I went vegan almost a year ago and have never felt better. Large amounts of meat aren't healthy anyways. I think people should do whatever makes them feel best, not what some blood type theory says. Try different things, and choose your diet based on what you can maintain long-term. What makes you FEEL best is what you'll be able to stick with for life (and therefore maintaining weight loss once goal is reached). Good luck finding what works for you.

According to the books I've read the blood type that we've all derived from our ancestors had to do with their diets, essentially. Basically, type "whatever" was in the colder regions, regions where mostly grains, fruits not dairy-eaters, i.e. The book I'm reading now talks about how to "eat instinctively." The author uses the horse and lioness as an example. He points out how horses eat oats in the fields rather than chasing squirrels or rabbits in search of meat and vice versus for the lionesses in the wilderness. Not everyone buys into every diet concept( how could we?).
What works for one may not work for another of course. It is always good to try new things until we find what does. Don't you think?

I'm confused how people in the 1700's would have known their blood type in order to eat in a specific way? Pretty sure it's not at all relevant....

I understand you are relating what you've read, I am address the information provided to you - not you directly - but that is a silly point. It's far more than instinctive eating. Carnivores have sharp teeth for tearig meat, certain digestive tracks for breaking down meat, predators have certain adaptations to help them hunt better, whether its eyesight, speed, etc. Herbiovores likewise. Even taste buds are adapted to attract animals to what they need to survive. Prey animals have specific adaptions to help them avoid being caught. They are specifically built for what they eat, it's not a matter of choice. A horse could not eat squirrels. It would be a huge amount of energy expenditure for them to catch one for little reward. Likewise a lioness cannot eat a herbivore diet.
It's not even close to the same idea.

You are literally comparing apples to oranges by saying, "What works for one may not work for another" using a comparison between a HORSE and a LIONESS. I guess what works for one mammal may not work for another, if that's what you mean?

Hello - I've been on the new lifestyle of eating for about 2 weeks; I've lost almost 5 pounds; I went to Dr. D'Adamo's website and did some analyses as I am A+. If you go to his website, he has loads of info with regard to your blood type ..... I took it a step further and purchased his Genotype book - lots of Q&A with regard to family history, body type, measurements (not the typical stuff - more like hip-leg ratio, finger print analysis - lots of good stuff)l, I also purchased his online program (one time purchase) called SwamiXpress - based on your genotype, it provides you with recipes and a guide back based on your allowable (beneficial) foods. As an A, I follow a more vegetarian based plan because we do not digest proteins well; I've always consumed more than enough protein so this was a change to choose from plant proteins; I've felt so much better, healthwise. I do count my calories on MFP, but am concentrating on more of the quality of food that I eat. I am a 56 yr old gal with hormonal weight gain over the past year or two - I've tried so many plans with little success and don't consider it a diet, but a new way of eating. I would recommend this to anymore - it just makes good sense and to work with your genetics, not against them. Any other questions - let me know.

Don't waste your money. There's nothing to this, scientifically. If there was, everyone with thread blood type would have he same food allergies, but they don't. Also, people with different blood types can have the same food allergies. That should be impossible if this "blood type diet" malarkey was true. It's just a money making scheme. It works based on the placebo effect.
