  • Twelve Metabolic Types

The autonomic nervous system plays a major role in the classifications of the metabolic types. The twelve metabolic types have been arranged into three groups:

  1. Group A, which includes the Sympathetic Dominant Metabolic types: One, Four, Six, and Eleven.
  2. Group B , which includes the Parasympathetic Dominant Metabolic Types: Two. Five, Seven, and Twelve.
  3. Group C , Balanced Sympathetic/Parasympathetic Metabolic types include Three, Eight, Nine, and Ten

Group A – Sympathetic – Vegetarian Type

Group A metabolizers are classed as Types One, Four, Six, and Eleven. These types have very strong or dominant sympathetic nervous systems. These types have very strong functions of the brain, pineal, anterior pituitary, parathyroid, thyroid, and adrenal medulla glands; heart, bone, muscle and connective tissue, kidneys, gonads (ovaries or testes), and uterus or prostate. Their muscles are usually quite well developed and show good muscle tone. Their hearts normally beat a little fast. Constipation is an ever-present plague. Frequently insomnia is a problem. Tension, hyperactivity and drive are their plight.

Sympathetics do not digest foods from their diet well. Actually, they digest less that 10% of their food intake. They assimilate about 40% of the digested intake. These supposedly vegetarian types do not like heavy meats as they cannot digest them well. These types do best on fruit and carbohydrates. If you go to a health food cafeteria bar you will see a few selections of green salads and about 20 feet of deserts. Sympathetic metabolizers will take a few spoons full of vegetables and 5 or 6 deserts. All one has to do to determine a sympathetic metabolizer is go to a cafeteria and observe those who load up on sweets. These sweets are easily digested and assimilated by them and feed their dominant glands and organs that give them their outstanding energy. Then they hop and jump around like a Ubangee Chief at a White Missionary Boiling.

Group B- Parasympathetic Carnivore Types

Group B metabolizers are classed as Types Two, Five, Seven, Twelve. The parasympathetic nervous system dominates these types. These parasympathetic metabolizers have strong function of the posterior pituitary, hypothalamus, parotid, sublingual (saliva) and adrenal cortex glands; stomach, spleen, duodenum, pancreas, liver, small intestine, colon, lymph and immune systems. Their Digestion is very good. They are not constipated, but to the contrary, tend toward loose stools and diarrhea. They have poor muscle tone. They are in general lethargic, slow, and fall asleep easily. They usually have a good reserve of strength.

Parasympathetic metabolizers can digest most anything (about 90% of their food intake). And they can assimilate about 80%. However, their glands and organs responsible for utilizing these nutrients (their get-up-and-go) are often and usually weak, defective and exhausted. Therefore, they do not utilize but 10% of what they assimilate. Then the major problems of the parasympathetic metabolizer focus and revolve around “storage” of these assimilated foods in form of overweight. It is most difficult or almost impossible for them to retrieve the stored nutrients. Taking the recommended nutrients fro these metabolizers does help a great deal but weight is their dilemma.

Group C – Balanced Sympathetic Parasympathetic Types

Group C metabolizers are classified as Types Three, Eight, Nine and Ten. These types have balanced autonomic nervous systems. The sympathetic and parasympathetic nervous systems work well together in a normal balance of glandular activity and metabolic function. Group C metabolizers have balanced metabolisms, which are neither strongly meat eating nor strongly vegetarian – they fall in the middle. They are both vegetarian and meat eating. Metabolizers in this category have the greatest freedom in what they can eat. Indeed, they enjoy and thrive equally on foods from both the vegetarian and meat eating categories. The balanced metabolizers burn their food neither too fast nor too slow. This is one of the reasons they do equally well on all varieties of food.

Balanced metabolizers generally need such nutritional support as Vitamins A, B-1, B-2, B-6, B-12, Niacinamide, Vitamin C, Bioflavonoids, Vitamin E, Folic Acid, Biotin, Pantothenic Acid, PABA, Calcium, Phosphorus, Magnesium, Manganese, Chromium and Zinc. Each of the balanced Types Three, Five, Nine and Ten needs these supplements but each type needs different amounts and in different ratios. They also require extra amounts of Hydrochloric Acid and Pancreatic Enzymes.

The balanced metabolizers can suffer from the conditions and disorders of either the vegetarian groups or the carnivore groups of metabolizers. They are prone to the following conditions and have the following characteristics, all of course, in moderation and generally not to the extreme.
