Metabolic Typing

Are we metabolically different? So says William Wolcott in his book, The Metabolic Typing Diet.
A discussion from the Native Nutrition Yahoo group as well as my nutrition consulting coursework prompted me to look into MT. I was curious: could we actually look at nutritional therapy for people based on their individual metabolic types and could there actually be major differences? So, here's my opinions on what I've researched so far...

Wolcott (2000, p. 17) mentions: "When optimum energy is available to your body on all levels -- to your cells, organs, glands, and systems -- then optimum (balanced and efficient) functioning, or good health, is possible." He feels that depending on your metabolic type, the foods (macronutrients: protein, carbohydrates, and fats) that make your body run efficiently will not necessarily be the same foods that help someone else. This metabolic type is dependent on several factors: autonomic, endocrine, oxidative, acid/alkaline, prostaglandin, electrolyte, blood, consititutional, and catabolic/anabolic types. All of these factors affect how quickly your body metabolizes what you eat (as well as what you drink, feed your skin/hair, breathe, etc.)

To boil it down to a nutshell, after you complete the questionnaire in the book, you end up fitting into one of three categories: Protein Type, Carbo Type, or Mixed Type (a little of both Protein and Carbo Types). This seems a little too simplistic for me, but perhaps it is that simple? I am concerned that with all the various factors mentioned in the previous paragraph, there are only three types.

Dr. Ross Hauser has also created a metabolic typing diet using animals (lions, bears, otters, monkeys, and giraffes - oh my!) to identify varying optimal levels of protein, carbs, fats, and even vegetarian tendencies for one type. You can take a test online at to see which type you are. I fell into the otter category (modified high protein diet with emphasis on greens). I think otters are cool animals, so it's fun that I eat like one! My DH turned out to be a monkey with a balanced diet, and he generally doesn't need to eat as much protein as I do.

Interesting stuff... I definitely have more to read!

  1. yes, yes and yes. I took that quiz and I am a lion - lots of protein and fat. It is so true.

  2. I eat like a lion, but I know my body needs greens or else it's not happy. So, an otter I am!I've noticed fat keeps me warm, better blood circulation. Go fat!

  3. Hi Erica,

    I'm glad you found Metabolic Typing! I'm an MT advisor and have had great results with it. There's much more to it than taking the test in the book. The three simple "carb, mixed, and protein" types factor in proportions, but not the specific foods that influence the oxidative and autonomic nervous systems. If you're interested in getting the most out of MT, I recommend that you take the advanced test, and considering your educational background, you may also want to look into becoming an advisor as well.

  4. Thanks Vin! Yes, I've realized that there is definitely more to it than just knowing the type one is. I would consider becoming an advisor AFTER I finish my immediate need to conquer Physiology!
