Metabolic Typing —
Discovering Your Personal Nutritional Needs

Without knowing your metabolic type, you are guessing as to what foods and supplements you should take. This chapter explains how you can develop a personalized nutritional program that gives you the results you want.

A person may be following a program of the best foods, the best supplements, and plenty of exercise — but how does he or she know that those really are the best foods for them? Each of us is different and has a different metabolism.

Many of the world’s leading scientists including, for instance, biochemist Dr. Roger Williams, author of many excellent and well-known books such as You Are Extraordinary, and Nobel Prize Winning Physicist, Dr. Linus Pauling, have proven this through their own research.


Basic Metabolic Considerations

Individuals are classified into ten basic types, which are named "Metabolic Types One through Ten." By classifying each person into their own proper type, it is possible to determine accurately what vitamins, minerals, foods, and other supplements would best support his or her own body chemistry. Equally important, it is possible to know what supplements and foods they should not have. With the knowledge of these factors, it is possible to design a program that has the fullest potential. All people fall into one of the metabolic types, that is to say they fall into one of the basic ways the body functions. Each person’s body takes in food, water and air. How a person uses these raw materials to maintain life differs from one person to another. This function of maintaining life is called metabolism and is normally defined as the sum total of all the chemical reactions occurring in the body. 

The Nervous System

The body has two nervous systems — the voluntary nervous system and the autonomic nervous system. 

The Voluntary Nervous System

The voluntary nervous system is that part of the brain and nerves that are under the control of the conscious mind. Activities that you have definite control over, like making decisions, walking, speaking and the like are controlled by the voluntary nervous system. 

The Autonomic Nervous System

The autonomic nervous system is that part of the brain and nervous system that carries on the functions of the body that we have very little or no conscious control over. The autonomic nervous system controls such activities as our heartbeat, respiration and reflexes (like what happens when a person sits on a tack).

The autonomic nervous system regulates the basic life-sustaining functions of the body such as the turning on and off of glands and organs, maintaining the acid/alkaline balance of the blood, saliva, and urine, digestion of food, balancing glandular functions, turning the cells on and off, and stimulating and retarding the body and its parts.

The autonomic nervous system is the master regulator of metabolism. It determines how efficiently and effectively the body uses food, water and air. 

The Autonomic Nervous System Consists of Two Divisions

The autonomic nervous system consists of two divisions. One division is called the sympathetic nervous system and the other division is called the parasympathetic nervous system. Each of these two divisions sends messages in the form of electric current to the different parts of the body. There is a nerve from each of the divisions to each part of the body. 

The Sympathetic Nervous System

The sympathetic nervous system sends messages that in general accelerate or speed up our activities. 

The Parasympathetic Nervous System

The parasympathetic nervous system sends messages that in general retard or slow down our activities. 

Three Groups — Ten Types

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

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


Group A — Sympathetic — Vegetarian Types

Group A metabolizers are classed as Types One, Four and Six. 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.

General Nutritional Guidelines for Sympathetic Dominant Vegetarian Types (Group A)

Of this group, Metabolic Type Six’s require the most nutritional support, the greatest number and strength of vitamins, minerals, enzymes and other nutritional factors that help the vegetarian type. Type One’s require the second greatest nutritional support. Type One’s need the support that slows down the sympathetic nervous system and speeds up the parasympathetic nervous system. Type Four metabolizers need the least nutritional support of this vegetarian class — they are the closest of the three to becoming balanced type metabolizers.

For nutritional support, Sympathetic Dominant Metabolizers most often need: Vitamin D; Vitamin K; Ascorbic Acid; Biotin; Folic Acid; Vitamins B1, B2 and B6; PABA; Niacin; Potassium; Magnesium; Manganese; Zinc; Chromium; Hydrochloric Acid; Pancreatic Enzymes and Amino Acids. Each of the vegetarian Types (One, Four and Six) need these supplements, but each type needs different amounts and different ratios. 

Metabolic Type One

Type One metabolizers come the closest of all the types to being purely sympathetic dominant people. One of the chief characteristics of Type One metabolizers is that they can burn carbohydrates slowly. Their bodies utilize the carbohydrates poorly and they are able to maintain their blood sugar level with very little fluctuation. If anything, their blood sugar level stays a little elevated. With this condition, they can eat mostly fruits and vegetables, maintaining their health and feeling well. These people are what are commonly called vegetarians. They very seldom if ever crave meats (except fish) and when they eat meat, they usually feel groggy and have a loss of energy. These people do not do well on lamb, venison, beef, sardines or salmon. They can do quite well on up to 100% of their diet raw. They should stress the following foods: whole grains including spaghetti, macaroni, breads, cereals; raw (unpasteurized) goats’ milk, eggs; white fish. They may use spices, 2-3 cups of coffee (non-instant), herbal tea, or an occasional alcoholic beverage or sweet dessert (made with unrefined sugar or raw, unheated honey). They enjoy and do well on nuts and seeds; rice; fruits and vegetables like apples, apricots, bananas, berries, grapes, oranges, pears, plums, grapefruit, asparagus, lima beans, beet tops, cucumbers, sprouts, lettuce, collards, dandelion greens, kale, mustard, turnip greens, spinach, and any leafy green vegetable. 

Metabolic Type Four

Type Four metabolizers are people who have strong sympathetic nervous systems but not nearly as strong as the Type One’s. Type Four’s are a little more balanced or non-strict vegetarians. These people usually have a genetic background of their ancestors coming from around the Mediterranean Sea — Spanish, Italian, Greek, Israeli, Arabic, etc. Type Four’s burn or metabolize their carbohydrates and sugars a little faster than the Type One’s. The Type Four’s that tend toward having diabetes can normally control it with diet alone.

To maintain optimum health, Type Four’s do well on fish, chicken, turkey, other fowl, beef (two times a week), almost all vegetables, a little fruit, sprouts, some citrus, eggs, and raw, (unpasteurized) goats’ milk. Most American "vegetarians" fall into this class. Type Six’s generally need about 60% of their food raw. They normally do not need as much nutritional support in the form of nutritional supplements as the Types One and Six. 

Metabolic Type Six

Type Six metabolizers are people who are basically sympathetic dominant. They fall into the vegetarian class of metabolizers. Type Six’s are very poor metabolizers — that is, they take in their food and nothing much happens. Their bodies do not utilize their food and they get very little energy from it and are generally sickly. Their assimilation or utilization of food is about 20% of normal. They almost always feel bad or not up to par. Type Six’s need about 60% of their food cooked. They need a great deal of supplemental nutritional support. They require more hydrochloric acid, vitamins, minerals, enzymes, etc. than either Types Four or One.

Type Six metabolizers should give care to the intake of whole and complete natural foods. All refined, processed, synthetic foods and additives must be avoided at all times. Type Six people do best when they stress the following foods in their diets: adequate amounts of fruits and vegetables including lettuce, green vegetables, onions, radishes, potatoes; whole grains including spaghetti, macaroni, breads; gelatin and other desserts made with raw sugar or unheated honey; natural jams, jellies, ice creams, mushrooms, nuts, seeds, and seafood and fowl, which should be preferred over other meats.  


Group B — Parasympathetic — Carnivore Types

Group B metabolizers are classed as Types Two, Five and Seven. These types have very strong or dominant parasympathetic nervous systems. 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 Are More Prone To:

Acids, cravings for

Alcoholism (to raise blood sugar)



Appetite, excessive

Arthritis; hypertrophic, osteo




Bladder, loss of control



Blood pressure, low

Bowel movements, easy to start

General Nutritional Guidelines for Parasympathetic Dominant Carnivore Types (Group B)

Metabolic Types Two, Five and Seven need some of the same nutritional support as do the vegetarian types, but for the most part, they need entirely different vitamins, minerals and foods.

Type Seven’s need more nutritional support than types Two and Five. Type Two’s have such strong parasympathetic dominance that they need almost as much support as Type Seven’s. Type Five metabolizers are more balanced and their supplemental support is not as much as the Types Two and Seven.

Parasympathetic dominant metabolizers most often need such nutritional support as: Vitamins E and B-12; Niacinamide, Pantothenic Acid, Choline, Inositol, Calcium, Phosphorus, Calcium Ascorbate, Bioflavonoid Complex, Zinc and Ribonucleic Acid. These metabolizers should eat at bedtime enough to carry them through the night. They should not eat leafy green vegetables or take large quantities of the B vitamins. 

Metabolic Type Two

Type Two metabolizers come the closest of all the types to being purely parasympathetic dominant people. One of the chief characteristics of Type Two metabolizers is that they burn carbohydrates very rapidly. Their pancreases work so well that carbohydrates and sugars burn or metabolize so rapidly that these people have a tendency to develop hypoglycemia — low blood sugar. When they eat only fruits, vegetables and sweets, their blood sugar rises and drops many times a day and their energy goes up and down like a yo-yo. When Type Two’s eat carbohydrates and sugars, which are metabolized so quickly, they become very weak and shaky after a spurt of energy.

Type Two metabolizers must have meat — preferably fatty, heavy, high purine meats such as lamb, beef, salmon, and sardines. They are usually the people who order their steaks very rare. By eating these fatty meats, they slow down their carbohydrate/sugar metabolisms. They feel they have eaten something that will "stick to their ribs." Their energy is released at a normal rate and they don’t suffer the ups and downs energy-wise that fruits and sweets cause them to have. Normally, these metabolizers don’t care much for sweets. They do well on root vegetables, cabbage, Brussels sprouts, cauliflower, carrot juice, and beans. They enjoy butter, cream, Danish pastries, cream puffs and foods with cream or butter added. They can do well by adding a small amount of whole grains.

Type Two people do very poorly on leafy green vegetables, candies, fruits, sweets, high carbohydrate diets and sugar pastries. They should limit the B vitamins and intake of potassium supplements. Type Two metabolizers usually have a genetic background from German, Scandinavian and Northern European ancestry. 

Metabolic Type Five

Type Five metabolizers are those persons who have strong parasympathetic nervous systems, but not nearly as strong as Type Two metabolizers. Type Five metabolizers are more toward the normal or balanced metabolism. They can tolerate a wide variety of foods. Type Five metabolizers do well on beef or lamb several times a week, seafood, salmon, tuna, raw (unpasteurized) goat cheese, avocado, beans, peas, lentils, celery, carrots, asparagus, butter, whole grain cereals and breads, some nuts and occasionally Danish pastry and raw (unpasteurized) goats’ milk cheesecake.

Type Five metabolizers are not as prone to hypoglycemia as are the Type Two metabolizers. However, Type Five’s can easily develop hypoglycemia if they indulge in too many candies and sweets. Many Americans fall into this class and do not do well as vegetarians. 

Metabolic Type Seven

Type Seven metabolizers are the sickly, weak, inefficient parasympathetic metabolizers. Their bodies do not utilize their food well and as a result they function very poorly. They almost always feel bad or sickly, functioning very sluggishly. It is difficult for them to maintain adequate nutrition to their individual body cells. Their body chemistry systems are quite inefficient and more than normal supplementation must be maintained at all times. Care must be given to the intake of whole and complete natural foods. All refined, processed, synthetic food and food additives must be avoided constantly.

Type Seven metabolizers are encouraged to stress the following foods in their diets: seafoods, sardines, salmon, brains, liver, heart, meat gravies and soups, non-colored unprocessed (unpasteurized) goat cheeses, beans, lentils, carrots, celery, butter, and cauliflower. Small amounts of Danish pastries, raw (unpasteurized) goats’ milk cheesecake and an occasional alcoholic beverage may be taken. Type Seven metabolizers function best on purine meats such as salmon, tuna, beef, lamb, and wild game. These meats should be preferred over others and used whenever possible and practical. Care should be given to adequately detoxify the bodies of these metabolizers.  


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.

General Nutritional Guidelines for Balanced Metabolizers (Group C)

Balanced metabolizers have different needs and requirements depending upon which type they are. Generally however, they do well on a large variety of food. 

Metabolic Type Three

Type Three metabolizers are balanced metabolizers. That is, their sympathetic and parasympathetic nervous systems are functioning in balance equally well. However, Type Three metabolizers come with bodies that are very inefficient. No matter what foods or supplements they take in, they are generally only going to use about 10% to 15% of them. Type Three metabolizers find it difficult for their individual cells to obtain adequate nutrition. All refined, processed, synthetic foods and food additives must be avoided at all times. Type Three metabolizers of necessity must take larger quantities of nutritional supplementation to maintain their nutritional health than any other type. They must eat food prepared in such a manner as to be easily digested. They should have a wide variety of foods, which enables them to get the wide spectrum of nutrients their bodies require.

Type Three (and Six and Seven) metabolizers are generally those with the poorest health. They have to keep constant vigilance over their diet and supplements. Generally they have inherited weak, defective bodies and very rarely will they ever have good health and feel really well if they are not extremely cautious.

Unfortunately, due to the stress of modern living and agribusiness, more and more Americans who have inherited good bodies have so exhausted and destroyed their bodies that they are now functioning in the Type Three (or Six and Seven) range. It would take supreme effort to rebuild and repair these bodies and put them back into normal optimum health again. 

Metabolic Type Eight

Type Eight metabolizers account for the greatest number of people. More Americans are Type Eight than any other metabolic type. Type Eight metabolizers have fairly healthy bodies. Their bodies can adapt to a wide variety of stresses and yet remain stable. Their autonomic nervous systems also have a wide range of adaptability. Type Eight people need a wide variety of foods each day. This permits them to attempt to obtain a large variety of nutrients required to operate their bodies efficiently. Nutritional supplements, like their food, must cover a wide spectrum. 

Metabolic Type Nine

Type Nine metabolizers are in the balanced class — their sympathetic and parasympathetic nervous systems work equally well. This type is the most difficult to understand. If these people had a choice, they would always prefer cooked food. Working with these people through the years has led to the conclusion that they truly cannot do well on raw foods. Evidently they have mutated to the point that they need cooked food to be satisfied. They generally require 70% cooked food and can comfortably handle 30% raw food. Type nine metabolizers do best when they can eat at Smorgasbord three or four times a week. In other words, if they eat a little of everything, they function best. 

Metabolic Type Ten

Type Ten metabolizers are the people with balanced and super efficient metabolisms. They need a wide variety of foods and supplements, but they do not require a large quantity of anything. Their bodies are so incredibly efficient that they need very small amounts of food. If they eat a normal meal, they feel more than satisfied. They can eat half as much as any other metabolic type. They do well on any food but often prefer raw fruits, vegetables, whole grains and unpasteurized goat cheese.

Recap of The Ten Types of Metabolism

Vegetarian Types

Type 1 — Needs no animal products at all. Can live entirely on fruits, vegetables and nuts. 

Type 4 — Needs some animal products such as fish, chicken, eggs and unpasteurized goat cheese several times a week. 

Type 6 — Combination of Types 1 and 4, but has horrible metabolism. Needs more food to make up for lack of absorption. 

Carnivore Types

Type 2 — Needs meat up to 14 ounces a day, preferably beef. Has little or no energy unless they eat meat. 

Type 5 — Needs meat to feel good, but less often, perhaps 2-3 times a week. 

Type 7 — A cross between Types 2 and 5 but with a horrible metabolism. 

Balanced Types

Type 3 — Has horrible metabolism. Only absorbs 15% of what he or she eats. Feels so bad that they often wish they were dead. 

Type 8 — Normal balanced metabolism. Can eat and benefit from all foods, provided they are wholesome. 

Type 9 — Needs 70% cooked food in diet. Hates raw food. 

Type 10 — Super-efficient metabolizer. Needs very little food and sleep, yet feels terrific.


How To Order Dr. Kelley’s Self-Test for the Different Metabolic Types

Dr. Kelley developed his Self-Test for the Different Metabolic Types to help bridge the gap of research to practical application. He realized that the overall state of health of this nation could no longer be maintained acceptable unless the nutritional needs of the people were brought into immediate and sharp focus. No one (doctor or patient) knows what a well-balanced meal is. Doctors have not been trained along these disciplines, nor do they have the time or inclination to educate themselves in these areas.

In order to make the most efficient use of research data, it must be related and applied directly to each individual to meet his specific needs. The problem then arises as to which data is significant for each patient. Dr. Kelley had to develop a system to accomplish this. It was decided that the most practical system would be an extensive questionnaire: Dr. Kelley’s Self-Test for the Different Metabolic Types. The test is bound in a book that contains hundreds of health questions. It includes complete instructions so you can score the results yourself (the results are compiled on an as-you-go basis during the completion of the questionnaire).

Taking the time (it takes a few hours) to complete the questionnaire will tell you whether you are a meat-eater, a vegetarian, or have a balanced metabolism. It will tell you which types of meats, fruits, and vegetables you should eat. Furthermore, it will tell you what supplements you should take, and, perhaps even more important, which you should avoid.

When you complete the questionnaire and follow the directions at the end of the book for scoring your answers, you will know where your body, at the present time, is functioning. There are three main metabolic types (Vegetarian, Carnivore and Balanced), and a number of sub-types (three in Vegetarian, three in Carnivore and four in Balanced). Each person will know exactly which of the three main types they are functioning in and also which sub-type.

After one follows the nutritional guidelines at the back of the questionnaire for their metabolic type for a few weeks or months they will want to take the Self-Test again to determine if their metabolism has switched to another type. Everyone should recheck their metabolic type every six months to a year, because it can change. If and when it does, one’s diet and supplemental program will have to be changed accordingly.

As one improves their blood chemistry, it’s possible for their nervous system to go into balance — giving them a balanced metabolism. This can take years, or it may never happen. However, I wouldn’t worry about it if it doesn’t happen. As long as you’re healthy and functioning normally — that’s what counts.


Note: Please see Book Order Form, page 171, to order Dr. Kelley’s Self-Test for the Different Metabolic Types.  


Metabolic Type Chart

Metabolic Efficiency



Metabolic Inefficiency

This is what we call the Metabolic Type Chart. It shows all 10 metabolic types and their relationship to each other, their sympathetic or their parasympathetic dominance and their metabolic efficiency.

On the left side are listed the sympathetic dominant types 1, 4, and 6. On the right side are listed the parasympathetic types 2, 5, and 7. And in the center column are listed the balanced types 10, 8, 9 and 3; these have a little of both sympathetic and parasympathetic dominating.

These 10 types are arranged on the Metabolic Type Chart on what might be called two sliding scales — one of them running horizontal and the other running vertical.

The horizontal scale runs from the extremely sympathetic type 1 to the more balanced but still sypathetic type 4 to the balanced type 8 to the parasympathetic type 5 to the extremely parasymathetic type 2. Ideally one should have a more balanced type of metabolism with good qualities from both sides.

Striking a balance between sympathetic and parasympathetic isn’t all that is desirable. It is also important to have a good, strong metabolism capable of utilizing raw materials with maximum efficiency. The vertical scale shows the scale from the exceptionally strong metabolizer type 10 to the good metabolizer type 8 to the poor sympathetic metabolizer type 6 to the poor parasympathetic metabolizer type 7 to the poor balanced metabolizer type 9 to the poorest metabolizer of all, type 3. The type 3 metabolizer only assimilates about 10% of what he or she eats.
