Genotype Diet

 By Mizpah Matus B.Hlth.Sc(Hons)

genotype-dietThe Genotype Diet is an expansion on the concept of the Blood Type Diet which was created by naturopathic physician Dr. Peter D’Adamo.

Dr. D’Adamo classifies people into six distinct genetic body types based on how certain genes and physical characteristics are known to occur in combination. He claims that customizing the diet and lifestyle to suit each genotype is the key to achieving weight loss and optimal health.

Although we can’t change our genes, we can influence the environmental aspects such as nutrition, exercise and how we respond to stress, which will in turn affect the way that the genes are expressed; either supporting health or contributing to illness.

The Genotype Diet Basics

The book includes a comprehensive test including questions about blood type, fingerprint patterns, physical measurements, family history, and other health parameters, which enables you to determine to which of the six genotypes you belong which include:

  • Hunter
    Tall and athletic, with a square jaw. Prone to inflammatory diseases such as allergies and rheumatoid arthritis. Blood type O.
  • Gatherer
    Emotional temperament and usually have a high BMI. Often have a history of crash dieting and have problems with appetite regulation. Blood type O or B.
  • Teacher
    Naturally flexible and enthusiastic nature. Susceptible to bacterial infections. Blood type A and sometimes AB.
  • Explorer
    Muscular, adventurous and intelligent. Sensitive to caffeine and medications. Any blood type but often Rh-negative.
  • Warrior
    Charismatic and highly strung. Often age prematurely. Blood type A or AB.
  • Nomad
    Very tall or short. Quiet, optimistic and rational nature. Often have sensitive digestive systems. Blood type B or AB.

Recommended Foods

The specific foods recommended vary depending on which genotype you belong to. Each genotype has a list of foods that are beneficial for that specific type.

General dietary structures and composition of protein, carbohydrates and fats will also vary for each type. For example a ‘hunter’ will thrive on a diet that contains generous servings of red meat whereas a ‘gatherer’ will do better on a predominantly vegetarian diet.

The health benefits of specific foods for each genotype are highlighted and D’Adamo explains the reasoning behind the tailored approach to address particular aspects of health for each type.

The online site provides recipes for each genotype. Examples of recipes for each type include:

  • Hunter – Grilled Steak With Red Onion and Peas
  • Gatherer – Asian Stir Fry
  • Teacher – Turkey Parmesan With Arugula
  • Explorer – Pasta With Turkey, Carrots and Cilantro Pesto
  • Warrior – Pan Seared Tuna
  • Nomad – Honey Barbecue Burgers

Exercise Recommendations

As with diet suggestions, exercise recommendations are specific to each type. ‘Nomads’ are advised to engage in gentle exercise such as yoga to help to reduce stress and balance their sensitive constitutions. The naturally athletic ‘explorer’ types should perform more strenuous activities that help them to break a sweat.

Costs and Expenses

The Genotype Diet book is available for $24.95 US however if you wish to access additional features such as recipes, diet calculators, message boards and access to Dr. D’Adamo and his team of experts, you will need to sign up for the online program which costs $4 per week, billed quarterly, at a cost of $52 per quarter.

You may cancel at any time and receive a refund for the unused portion of your subscription, other than a minimum 5-week charge of $20, which is nonrefundable.


  • Customized program to suit specific health issues and body tendencies.
  • Supported by a large number of scientific studies.
  • Provides exercise and lifestyle advice in additional to diet recommendations.


  • Necessary to sign up for the online program to access recipes. The book provides food lists only.
  • Meal preparation may be difficult when members of a family are different genotypes.


The Genotype Diet is supported by scientific research though it appears that many of the changes that are observed in regard to health and weight regulation may be due to general diet and lifestyle improvements.

Nonetheless if you like experimenting with different ideas and learning about the science of nutrition and health this program may provide you with new inspiration to make some beneficial adjustments to your current diet and lifestyle.

  • Rachel

    I fit into like three categories.


  • Paul

    I have had hypertension, an enlarged heart and cirrhosis of the liver from obesity (max BMI 48+). After eighteen months on an individualized version of the Genotype diet, my GP is plannig to reduce my hypertension medication. I have lost about 80 lbs with little exercise – as my stamina is still low. The weights: max over 400 lbs, current 320 lbs, goal 220 lbs.

    GP was pushing the services of a bariactric clinic, but I prefer what this diet has done instead! That is some potent Kung-fu!

  • Diana

    I’ve been following the GenoType Diet since 2007. I am a Warrior. If I didn’t find this diet, I’d be 100 lbs heavier than I am LOL! It got rid of horrible morning vice grip headaches I was having after only 2 weeks on it. Dr. D’Adamo has studies to back up his science, many from PubMed.

  • Edna

    P.S. I’ve lost 83 lbs on the blessed thing and am going for 7 more. Just saying. It rocks.

  • Edna

    I have been on the GenoType Diet since Thanksgiving (appropriate!) 2008, so for 2 years and 5 months. I was on the Blood Type Diet before that, since 1997. I will be on the GenoType Diet for the rest of my life. Why? Well, I agree with every word in Sarah’s post of October 11, 2009, so I won’t repeat it. I’ll just say, when you find the right diet for you, you won’t feel starving, deprived and ruled by cravings. The right diet for you will make you feel steady, satisfied, in balance, energized and strong. The GenoType Diet is that diet for me.

  • Grolec

    I have had similar results to Sarah mentioned in the comments below. I have been following the recommendations with few exceptions and have noticed a drastic increase in energy. Even if I have not slept much the night before, I can make through my work day without difficulty and caffeine (something I struggled with severely prior to the dietary changes). I originally started with the “Blood type diet” just over two months ago and have recently been implementing the recommendations for the hunter profile found in the “Genotype diet”. I have never had weight issues, but have always had problems with my energy level. I have been limiting my wheat, corn and dairy consumption and increasing meat intake instead along with recommended vegetables. I sometimes work very long hours at times seven days a week. In the past it was critical that I slept between 7 and 8 hours every night to properly function the next day. Now, I am able to perform my job even if I have only received half that amount. I am not endorsing going without sleep (as it is something needed to maintain good physical and mental health), but sometimes my schedule requires it. Since I have benefited from this program, it is clear which side of the fence I am on. For those straddling the middle trying to decide whether this plan is right for you, I hope this as well as the other comments on this page is of help to you.

    I have a nursing background, read this book thoroughly, and found the scientific basis quite believable. Humans have around 30,000 genes, which are responsible for all our millions of inherited traits – yes, personality as well, not just physical traits – so it is quite possible that a single gene could be responsible for a tendency to enthusiasm AND the immune system’s response to bacteria, for example. But Dr D’Adamo is talking about traits, not absolutes – we are all heavily influenced by our cultural environment as we grow up. Hence, a naturally enthusiastic person could easily have this trait stifled by their upbringing. As with the majority of medical research, I suspect Dr D’Adamo has had to work with data sampling, meaning that if 70% of subjects showed a correlation, then the theory is proven. (70% would be a strong correlation, by the way). Again, this means there is always subjectivity – but that is where science is up to, so it is all we have to go on. The genotype book is brilliant, in my opinion, because it quite simply encourages the reader to try a particular food and ask himself how that food makes him feel. That is the real key to optimum nutrition, as of course we are all different in so many ways. Naturally, you don’t need a book to do these kind of self-studies, but it often helps to have a framework to start with. So I would recommend this book – but approach it in an intelligent, questioning manner and don’t be afraid to deviate from the text where you find something that personally suits you better.

    He averiguado mi genotipo, y me ha dada cazador, pero no me coincide que no soy alta, solo mido, 1.55. Puedo ser de este genotipo?
    (I found out my genotype, and has given me the hunter, but I’m not high line, just my height, 1.55. I can be of this genotype?)

  • wendy

    Huh? Where’s the scientific research…????

  • edgardo rivera

    El libro esta muy interesante por que te explica practicamente 6 tipos de dieta. Todo ser humano es diferente pero se puede adaptar a una de las dietas que se explica en el libro.

  • yunilda

    is very good but i need in spanish,please

  • diana

    I tried figuring out my genotype but fit in 2 or 3 categories… how can you filter it or get it so you know exactly what you are?

    • None

      By your blood type

  • Hector

    I just ordered the book.I have a serious condition,an auto-immune issue, which the book was spot-on about. I will check back after trying it out for a while.

  • Sarah

    The blood type diet was good, but this is AMAZING!! Everyone who I have helped figure out their Genotype is thriving beyond hopes and expectations. I have tried every diet/ food lifestyle from blood type O diet, to being vegan for 12 years to raw foods, alkaline, food combining, and macrobiotic. Being on the Hunter diet has given me the energy, clarity, focus, strength, agility, flexibility, and endurance I have always known I should have. It is worth every minute of extra care, work it takes to do it.

  • John

    I almost died on this diet. It is complete brainwash. Stay away. For more information search blood type diet on wikipedia. They are all about deceit. Don’t do it!

  • Patrick

    I found a lot of the information in the blood type diet to be useful, but limited–eating for my genotype, much less so. Yes it is more expensive to eat less common foods, and harder to find a lot of things–but it is possible to eat this way–even in Southern New Jersey! I have not had an antibiotic, or needed to see a doctor for I don’t know how long–since I used to eat out of a box. I have not been sick, except for mild symptoms that my body takes care of, for over 3 years. I think this diet is great for people that take full responsibility for their health.

  • Melissa

    I think some of his information makes sense, especially after seeing some research online related to some of his discussions and other scientists input. However, the food lists are VERY restrictive, unless you have easy access to ostrich, kudzu, moose, purslane (what is that?). I don’t have the money or easy access to the “superfoods” listed. And easy access, affordable foods are on many of the “toxin” lists, such as bananas, tilapia, even wheat flour. Very unrealistic…. or if I had my personal meal planner and lots of money….I can dream, right?

    • richard

      I’m an Explorer, your toxin list seems like maybe explorer as well

      well as long as there organic, for me organic bananas are good, and talapia is okay for me like if I had quinoa with it,organic white/pinto beans or amaranth with it, the explorer can have red rife wheat(neutral) and actually the forms of wheat teff,100% sprouted wheat and spelt are super foods for the explorer. Kamut wheat can be tolerated as well, well for me anyway. I hate the seafoods list the Explorer is the only one the Tilapia is a bad food for.

  • amy

    Absolute nonsense. How is there any link between enthusiasm and a sensitivity to bacterial infections? These groupings are completely arbitrary. How on eart could they deduce a whole diet plan based on this?

    Nobody on this planet at this stage knows enough about the human genome to make these inferences.
