Blood Type Diet Review: Does it Work?

Is your health tied to your blood type?

Top Rated Diets of 2017
What is it?

The Blood Type Diet is a weight loss diet that recommends eating certain kinds of foods depending on one’s blood type. It’s claimed to be a scientific way of eating that says your genetics have a preferred way of eating to support overall health.

Blood type also helps determine what kind of reaction the body will have with stress, disease, and food. The belief is that the reason why not all diets work for all people is because selecting a proper diet depends on your unique genetics. Our review experts have analyzed many diets and the most effective one for weight loss is the 18Shake Diet. It combined a fat burning diet pill and an appetite suppressing meal replacement. When combined they help maximize weight loss with only natural, stimulant free ingredients. Learn more information about the 18Shake Diet by visiting the link here.

Blood Type Diet Ingredients and Side Effects

Depending on one’s own blood type, there is a specific diet plan outlined:

• Type A: Vegetarian diet that is rich in fruits, vegetables, legumes, whole grains, beans, and preferablyfresh and organic foods. This is because people with this blood type have an immune system that is susceptible to damage. Tai chi and yoga are advised as forms of exercise.

• Type B: There is no allowance for lentils, corn, wheat, buckwheat, lentils, sesame seeds and peanuts. It emphasizes eating eggs, green vegetables, dairy, and any kinds of meats other than chicken.

• Type O: This diet is rich in protein and offers all kinds of meats with a limit of dairy, grains, and beans. Supplements are also advised to help improve stomach issues that are caused by this blood type. Jogging, martial arts, contact sports, and biking are advised for an hour a day. Weight gain is caused by gluten and other foods which are limited.

• Type AB: This diet avoids alcohol, cured or smokedmeats and caffeine. It’s advised to eat dairy, tofu, seafood, and green vegetables. Those with this blood type have low stomach acids which make it harder to digest foods. It’s also claimed that people with this blood have a much higher risk of things like cancer.

There are issues with this diet which Web MD has highlighted:

“a major review concluded that no evidence exists to support benefits of blood type diets”

“It’s likely that you would lose weight, though, because the diet can be very restrictive”

Depending on the blood type, there are some extreme restrictions. This can promote side effects and deficiencies if one is not careful. There is also no evidence that this diet is based in real science. A review by the Belgian Red Cross in Belgium found:

“Blood type dietslack supporting evidence”

Yet another clinical review by PLOS One found:

‘Blood-Type’ diets is associated with favorable effects on some cardio metabolic risk factors, but these associations were independent of an individual's ABO genotype, so the findings do not support the ‘Blood-Type’ diet hypothesis”

Due to the lack of proof behind this diet, it’s unlikely that one has to eat for optimal health according to their blood type. Overwhelming science adds how this diet is not necessary. To see which weight loss diets were rated as the best for weight loss, visit the link found here.

EDITOR’S TIP: Combine this diet with a proven meal replacement such as 18 Shake for better results.

Blood Type Diet Quality of Ingredients

One’s specific diet will be determined by their blood type. Certain people will be allowed only a strict vegetarian diet with no allowance for meats. Other diets have restrictions which only allowed a certain amount of foods with recommended supplementation.

However, no evidence has proven this to be an effective way to schedule one’s meals. The registered dietician Katherine Zeratatsky mentions:

“There’s no sound scientific evidence that the so-called blood type diet is any more effective or any more beneficial for weight loss than is any other diet”

There are potential restrictions on this diet which can have negative effects. Web MD has also stated that in terms of weight loss:

“any weight loss on this diet has not been linked to your blood type”

No information is provided by the creator of this diet to help show how specific food choices were selected per one’s blood type.

No proof is offered either by those who promote this diet. Click this link for a comprehensive listing of the highest rated weight loss diets.

The Price and Quality of Blood Type Diet

There are multiple books available but the one often cited sells for $12.21 on Amazon.com. Other pricing depends on the cost of whole foods one has to purchase depending on their specific diet plan. Web MD has also stated:

“The diet may quickly become expensive, too, since the author recommends you by organics as well as his own line of supplements”

As mentioned there are multiple reviews and clinical studies performed which have shown this diet to be not only unproven, but also potentially lacking in certain nutrients.

There is no link between blood type and what kinds of foods are optimal for health and weight loss. Blood type is not a determining factor on what one should be eating. Due to this lack of proof, it makes the Blood Type Diet a poor quality diet.

Business of Blood Type Diet

The main version of the Blood Type Diet is featured in a book written by a Dr. Peter J. D’Adamo, a naturopathic physician. The main book which explains this diet is called “Eat Right for Your Blood Type”.

The field of medicine the creator practices is called naturopathy, and it’s an alternative medicine which often recommends herbs, acupuncture and other unproven techniques to promote health.

It’s considered pseudoscience and is not accepted in any true medical school. Though one can have a doctor title if one has a degree in this, it’s not truly an accepted profession in the medical community. These forms of alternative medicines have no proven science and that’s why it’s not allowed in true health based organizations.For a comprehensive list of the best weight loss diets, click on the link cited here.

Customer Opinions of Blood Type Diet

Here are some select quotes taken from customer reviews:

“Another Dangerous and Poorly Substantiated Fad Diet”

“it looks like this diet isn’t really backed by any scientific proof”

“There is absolutely no scientific basis for the claim that blood type has any benefit whatsoever”

“I have come to realize I can’t follow it I have been sick for 2 ½ years now”

People often mentioned how it’s incredibly difficult it is to follow this diet, as certain blood types are more restricted in food choices than others. For some it was difficult to suddenly stop eating all kinds of meat. It leads to difficulty selecting what foods to eat, as there are many banned healthy foods.

There are also issues people had with the lack of science to back up the claims made. Many who researched found that there is no proof that this diet is both safe and effective. There were also problems with those who tried this diet and could not sustain it for long. Some experienced nutritional deficiencies and ill health with repeat use.

A few users who made sure to get their medicals done noticed how there were negative health markers.

Conclusion - Does Blood Type Diet Work?

The Blood Type Diet has a very specific recommended diet depending on what one’s specific blood is. While this seems to be based in science, there is no available proof that shows this has any weight loss or health benefits. Many clinical studies and dietician reviews have shown it to be an unproven diet. There is no evidence that blood type has any effect on what kinds of foods one should select. Users have also mentioned how this diet is hard to maintain, and people were disappointed to find there were no health benefits. There’s simply no reason to ever use this diet as it was created by a doctor who specializes in an unproven form of alternative medicine.

Our review experts have found that the 18Shake Diet is the most effective overall for weight loss. It offers a meal replacement that can suppress appetite for hours alongside a fat burning diet pill. When combined they help to maximize weight loss without the use of artificial additives, stimulants, colors, preservatives, or any cheap and unwanted fillers.

The Blood Type Diet is a great way to stay healthy and very easy to follow, it is not restrictive once you get used to it because you won't want to eat the "avoids" any more. I have dropped a pants size without even trying and do not have to work hard to maintain my health.

This diet is the closest way to the way I eat normally. I've tried every diet from Atkins to Weight Watchers and I always came back to this diet. It makes me feel healthy and balanced.

This diet is ver similar to the way I like to eat naturally..I am an A blood type and I've tried other diets from Atkins to Weight Watchers and I always went back to the Blood Type Diet because I felt good, and balanced and was able to lose weight.

Eight years ago I was 80 lbs heavier than I am today. Had skin, breathing, aching joints, brain fog, high blood pressure, yeast problems along with other problems. When I first found BTD, my doctor had me taking water pills (which only made me feel worse) and was ready to put me on blood pressure medicine. I didn't want to be a pill popper for the rest of my life. BTD fell into my life, more than once as I kept trying to avoid it. Once I got onto the diet (only took less than two weeks to convince me) I knew that this was the way of life for me. Started cooking from scratch again and eliminated all processed foods and stuck with the foods that Dr. D suggested. After seven years, Dr. D came along with the Genotype diet. For over one year now I have been a gatherer on this way of life and things have improved even more. I know a lot of people are sceptical of this way of eating. Don't knock it till you have tried it...and if if isn't working for you...you aren't following it properly.

The BTD family members and Dr. D and affiliates are not scammers. We are just ordinary people trying to get on with our lives living it without pain and suffering from the foods that we ingest. Have you read all of the garbage that gets put into our food nowadays. That is what is making us sick. Unless you take your health and food into your own hands...your doctor will be seeing you regularly.

I have suffered from mild acne for 30 years.... the BTD completely cleared my skin. I have mild arthritis from years of distance running, and I have found some relief in following the diet.. I hope to find more! I had been a vegetarian for 15 years ... the acne was going on during this time.. and my cholesterol was sky high at 250 something.... once I started on the O diet, it DROPPED to below 150. I personally loved being a vegetarian, but I feel SO much better eating Dr. D'Adamo's way...

It works as far as it goes. I have been on it for a couple of years, but find that the information about what to eat for my blood type is incomplete and the information is not readily available. You need to use common sense as far as how strictly to follow it. It confirmed what I know about myself from previous experience so there must be a basis that is sound. I don't think it is the whole story however.

SCAM ALL THE WAY, STAY AWAY. Look it up on wikipedia, they'll tell you. The forum is full of scammers and dumb followers. They all get you sick and try to make you buy more. Dr. D'ADAMO is one sick person!!!

I have and it's all brainwash with a diet. Don't do it!!!

posted Dec 6th, 2008 12:23 am



Excellent plan for dealing with disease. D'adamo's new book, The Genotype Diet, addresses weight loss more specifically.

posted Oct 19th, 2008 2:06 am



Works better than any other diet that I have tried. I started it 7 years ago because of health problems. In that time I have tried other diets, but always return since I get sick on the other diets and I do not like being sick.

It has greatly reduced headaches. I only get hives when I eat foods not recommended for my blood type. Digestion is greatly improved.

This isn't a diet! It's a lifestyle change for great health. I've been overweight all my life and the only way I ever lost weight was to exercise 2 hours a day and hurt my body. I couldn't even kneel down without major pain. I tried this "diet". What a difference. Eating whatever I want that I'm allowed for my type I loose about a pound every week or two without trying. It's easy! No injuring exercise. I walk and bike ride when weather permits. Then I loose more! The best thing is my joints don't hurt! I can do anything now with no pain!

This diet isn't necessarily about weight loss. Both my sisters swear by it today, they have been on the diet for a year. Up until they both started this diet, they were in and out of the doctor. One was on Nexium for acid reflux, and the other was soon to be. When they were prescribed the purple pill, they were told they would never get off. Today both haven't any heartburn or acid reflux problems, and they have only needed to go to the doctor for the usual checkups and things. This diet is strict for both, but they live by it today, and because of their success, the rest of our family is taking thier lead and following. Even some of their friends have followed. The only really big problem with this diet is that some of the foods are hard to come by unless you have a Whole Foods or the likes near by. Kroger isn't so good at carrying some of the types of products these diets recommend.

All I can find are diets in regard to a, b, o types. I am a A neg. Do I follow the A type diet?

there are two diets I would like to see reviewed: the pH balance diet and the metabolic typing diet. Thnx

I have. It worked better for me than South Beach. I lost about 20lbs. Ive always had a lot of food sensitivities and reading the book made sense for a lot of those. I've always had trouble with diets because of my sensitivities. I can't eat a lot of grains, milk, soy, etc. So it helped me find a way to eat well and feel much healthier.
