Blood type O - Vegetarian

  1. 15 years ago

    Dr. Kelly,

    I've been reading with great interest your 'guidelines for blood type O'. I'm in the process of deciding whether or not to be a vegetarian, primarily for health reasons. I'm blood type O and it says that this type is the 'hunter, meat eater' type, and that this type is quite well suited to eating meat.

    I've been put off meat over the years by the fact that so many chemicals are used in its production. We're told that these chemcials can cause cancer, although it seems everything causes cancer these days. I also feel that its a drain on the worlds resources to produce so much meat. Producing grains and cereals etc is so much more efficient.

    My question is whether or not its healtheir to be a meat eater or a vegetarian, particularly being Blood Type O? Can a person with blood type O acheive the same level of performance and energy being a vegetarian? If it is possible to achieve high energy levels being a vegetarian, what foods are best to eat to satisfy the need for proteins that O types require?

    Thanks for your time!

    Hello Irene,

    Excellent questions.

    I am also a blood type O and was a very strict vegetarian for almost fifteen years while remaining extremely active with regular exercise, running, and mountain biking. Since there are world class athletes in many different sports who claim to be vegetarian, it is apparent that vegetarians can often achieve the same levels of performance and energy.

    I gave up strict vegetarianism about five years ago after noticing a gradual, but continual, loss of muscle mass. Since then my protein choices include fresh, deep ocean fish (especially salmon, halibut, and cod); raw, organic, free-range chicken eggs almost daily in a protein drink; organically raised chicken, beef, or lamb; wild game such as deer or elk; organic seeds and nuts; and organic goat cheeses. My muscle mass has been restored and has, actually, increased significantly.

    In response to your last question, I would strongly suggest that you at least include organic, free-range eggs if you choose NOT to eat meat. In addition, you may wish to add organic goat's milk and cheeses as well as the organic seeds and nuts. Sprouts are an excellent source of protein and minerals. Vegetable juices made with organic produce is also very good. Include lots of green vegetables (about 2 ounces per glass).

    You will notice that soy products are not included in the list (you can use fermented soy products such as miso, tempeh, and tamari as condiments) nor are milk or milk products (including whey). I never recommend milk or milk products. They are much too difficult to properly digest.

    Hello Irene,

    I have not found the Blood Type B diet to be as successful as the Blood Type O and the Blood Type A diets. If you follow as much of the "General Dietary Recommendations" (look in the articles section on my website - ) as you can, you should be able to make some positive changes.

    Regular exercise is also important.

    Hello Lata,

    It is extremely difficult to say for sure without a complete history and examination, but I suspect you have a hormone imbalance with a relative deficiency of progesterone in relation to estrogen.

    My first recommendation would be for you to see your MD, preferably one well versed in the diagnosis of endocrine system function. The results of this examination should give you some major clues as to the cause of your problem.

    Next suggestion would be for you to have a saliva test to evaluate your hormone levels. Home test kits are available via the Internet at
