Core Premises - The Healthexcel System of Metabolic Typing®

Why is the knowledge of one's Metabolic Type® [1] important? ... Because, according to Healthexcel's concepts, without knowing what it is, no rational basis exists for the selection of proper diet and nutritional supplementation, since how foods and nutrients behave in a given individual's metabolism cannot otherwise be known. This conjecture is based upon logically sequential premises that comprise the core of Healthexcel's unique paradigm of balancing body chemistry, maximizing metabolic efficiency, and building health through The Healthexcel System of Metabolic Typing® [2]:

  1. The human body is genetically designed and programmed to be healthy
    • Every one of the body's approximately 37 trillion+ (37,000,000,000,000) [3] cells "knows" exactly what to do and how to do it properly, as per its genetic "program" found within every cell

  2. The Healthexcel System of Metabolic Typing® views the body as comprised of many different levels which are organized in a hierarchical fashion based upon complexity and function, whereby each higher level is protective of each lower level:
    • organism (highest, most complex level) --->
    • system --->
    • organ/gland --->
    • tissue --->
    • cell --->
    • nuclear --->
    • sub-nuclear

  3. Health requires:

    • Homeostasis through Adaptation, i.e., the maintenance of Biochemical Balance and Metabolic Efficiency (biochemically, physiologically, and metabolically) in a state of dynamic equilibrium throughout all the various levels of the body

    • The proper and timely quantitative presence of nutrients at the appropriate levels in the body

    • The proper and timely qualitative utilization of nutrients at the appropriate levels in the body

      [All metabolic processes require the presence of the right amount of nutrients, in the right balance, at the right place, at the right time, and in the right form (one that is optimally utilizable by those processes)]

  4. Systemic efficiency (e.g., immune system) is based upon Organ/Glandular efficiency (e.g., thymus gland), which is based upon Cellular efficiency (e.g., thymus cells), which is based upon the optimum quantitative and qualitative availability of energy to the cells (e.g., through cellular oxidation), which depends on the ingestion, digestion, absorption, transportation, assimilation and the timely (quantitative and qualitative) utilization of the genetically based proper balance of biochemical constituents (nutrition) provided at the right place, the right time, and in a form that is optimally utilizable

  5. There are trillions of biochemical reactions that take place daily (e.g., a billion methylation processes every moment we are alive) as part of the innumerable life-supporting processes of metabolism. But they occur neither independently nor without the direction of Fundamental Homeostatic Controls...

  6. ...Therefore, the potential for sufficient adaptation to stressors, continual homeostatic balance, and thereby good health is a measure of the body's ability to manage stressors (spiritual, mental, emotional, structural, biochemical, environmental) through its capacity for the creation, maintenance, and control of energy via the dualistic, diphasic, Fundamental Homeostatic Control Processes / Systems / Mechanisms [4], of which Healthexcel recognizes thirteen. They are:

    • Autonomic Nervous System (master regulator of metabolism, neuro-endocrine/hormonal balance)
      Sympathetic vs. Parasympathetic [5]

    • Carbo-Oxidative System (conversion of nutrients to energy via intermediary carbohydrate metabolism, involving Glycolysis, Citric Acid (Krebs) Cycle, Beta Oxidation)
      Fast Oxidation vs. Slow Oxidation [6]

    • Lipo-Oxidative Processes (involving fatty acids/sterols balance, cell membrane permeability, aerobic/anaerobic metabolism)
      Catabolic vs. Anabolic [7]

    • Steroidal Hormone Balance (DHEA/ Androgens/ Estrogens Pathway vs. Preferential Stress Pathway)
      Cortisol vs. DHEA

    • Neurotransmitter Balance (brain chemistry/function)
      Excitatory vs. Inhibitory Neurotransmitters

    • Electrolyte/Fluid Balance (hydration/dehydration)
      Electrolyte Excess vs. Electrolyte Deficiency [8]

    • Acid/Alkaline Balance (6 potential acid/alkaline imbalances [Metabolic Acidosis, Metabolic Alkalosis, Respiratory Acidosis, Respiratory Alkalosis, Potassium Excess Acidosis, Potassium Depletion Alkalosis], resulting from 7 causal factors [autonomic, carbo-oxidative, lipo-oxidative, electrolyte/fluid balance, respiratory function, endocrine efficiencies (kidneys, adrenals, ovaries, testes, thyroid, posterior pituitary, parathyroid), and the chronic dietary imbalance with respect to acid/alkaline pH of foods (the least impactful)]
      Acid vs. Alkaline [9]

    • Prostaglandin Balance
      Series 1 + Series 3 Prostaglandins vs. Series 2 Prostaglandins [10]

    • Methylation
      (Over-methylation / Under-methylation)

    • Immune
      (Th1 vs. Th2 vs. Th17)

    • Endocrine System (Endocrine Type as per dominant energy gland)
      Pituitary vs. Thyroid vs. Adrenal vs. Gonad [11]

    • ABO Blood Type
      Type O vs. Type A vs. Type B vs. Type AB [12]

    • Constitutional Elements (constitutional qualities of foods interacting with the constitutional qualities of the body)
      Vata vs. Pitta vs. Kapha [13]

  7. The critical importance of nutrition in the question of health vs. disease is grasped through the understanding that every nutrient and every food have specific stimulatory or inhibitory effects on one or more of the Fundamental Homeostatic Control Mechanisms listed above

  8. Genetic inheritance (in setting metabolic "design limits"), along with the impact of environmental and lifestyle factors (that literally "turn on" and "turn off" genes), define one's Metabolic Type® (all aspects of biochemical individuality—spiritual, mental, emotional, structural, physiological, biochemical—as expressed through the Fundamental Homeostatic Controls above), thus forming the basis for the determination of individual nutritional requirements

  9. Different Metabolic Types require different balances of foods, micronutrients (vitamins, minerals, etc.), and macronutrients (protein/fat/carbohydrate ratios) in their dietary intakes to meet the dictates of their biochemical individuality for obtaining and maintaining functional peak performance and optimal health

  10. Failure to meet the genetically based nutritional requirements for the Metabolic Type lays the foundation for dysfunction, failed defense, insufficient adaptation, sub-clinical health complaints, and ultimately degenerative disease

  11. The Genetic Type (i.e., genotype, the Metabolic Type one is born with) can functionally change due to stress, environmental factors, improper diet, stimulants, chemical abuse, illness, etc., to a different Metabolic Type, therefore one's Functional Type (i.e., phenotype, the Metabolic Type one is currently functioning as) can be different from one's Genetic Type (genotype)

  12. The Functional Metabolic Type (phenotype) defines and dictates the current way the body reacts to biochemical stimulation (foods, micronutrients, macronutrients)

  13. Different Metabolic Types React Differently To The Same Nutrient(s)
    • What is acidifying in one Metabolic Type will be alkalinizing in another Metabolic Type
    • What is stimulating in one Metabolic Type will be sedating in another Metabolic Type
      [see #18 below]

  14. Two People With the Same Metabolic Type Can Have Different Diseases —
    • How degenerative conditions manifest is largely determined by one's genetic "weak link"
    • Two individuals may have identical nutritional imbalances, but one may develop diabetes, while the other may develop arthritis

  15. The evaluation and determination of biochemical, metabolic individuality (Metabolic Type) and thereby the determination of individual ecological lifestyle requirements and patient-specific (not disease-specific) protocols is the purpose of The Healthexcel System of Metabolic Typing®

  16. Diseases (and all adverse symptoms) should not be viewed as entities for which disease-specific or symptom-specific treatment/therapy is required, for in actuality, dis-eases are the expressions of underlying biochemical imbalances in one or more of the Fundamental Homeostatic Controls in the Metabolic Type they are manifesting
    • This biochemical reality demands that the person who has the disease (i.e., the Metabolic Type) should be treated ("patient specific")—not the disease that has the person ("disease specific")

  17. No diseases or adverse symptomatology can exist without the involvement of an imbalance in one or more of the Fundamental Homeostatic Controls as expressed through the Functional Metabolic Type

  18. Any given disease may arise from opposite biochemical imbalances in different Metabolic Types. (Two people with the same disease may have opposite biochemical imbalances). Therefore...
    • ...A successful, standardized, nutritional/biochemical treatment (allopathic) for any given disease—one effective nutritional solution/remedy for a given condition that is correct for all people with that condition—is not possible

  19. Any given nutrient can have opposite biochemical influences in different Metabolic Types (one's food is another's poison), depending on which Fundamental Homeostatic Control is being affected or is dominant. This phenomenon was coined The Dominance Factor in 1983 by WL Wolcott[14]. Therefore...

    • ...What can correct a condition in one Metabolic Type, can worsen the same condition in a different Metabolic Type, or have insignificant to no effect on a third Metabolic Type

    • Thus, the allopathic (symptom-treatment) approach using nutrition to treat disease has no logical basis; chance, not scientific rationale, will dictate success or failure of nutritional allopathy (pharmaceutical nutrition) in the treatment of degenerative conditions

    • Furthermore, all scientific research as regards the effects of nutrition on human metabolism that is not performed on subjects of a homogenous Metabolic Type will always result in variable and inconclusive results (This is why all results of nutritional research conclude that the nutritional substance tested improved a condition in some, had negligible effect on the condition in others, and worsened the condition in a third subject population)

  20. Nutrients behave differently on different levels of the body
    Differences in nutrient behavior are seen in terms of their:
    • Stimulatory/catabolic/acid effects, or
    • Sedative/anabolic/alkaline effects

      due to their influence(s) on:

    • Hierarchic Organizational Levels
      [For example, Phosphorus is acidifying at the Systemic level via stimulation of the Sympathetic System but is alkalinizing at the Cell level via decreasing the rate of carbohydrate oxidation thereby lowering venous plasma CO2 and carbonic acid], and

    • One side or the other, of one or more of the dualistic, diphasic, Fundamental Homeostatic Control Systems (inhibiting or stimulating sympathetic or parasympathetic, fast oxidation or slow oxidation, anabolic or catabolic, acid or alkaline, etc.) [For example, potassium is sedating and alkalinizing when stimulating the Parasympathetic division of the autonomic nervous system, yet is acidifying when increasing the Carbo-Oxidative rate]

      Note: The acid or alkaline property of a nutrient or food is only one of many potential determinants of overall systemic pH. Determining influences include but are not limited to: autonomic (sympathetic/parasympathetic), carbo-oxidative (fast/slow oxidation), lipo-oxidative (catabolic/anabolic), respiration, electrolyte balance, organ/gland influences (adrenal, kidney, pituitary, thyroid, gonad), and finally, chronic ingestion of acid or alkaline foods. It is not so much the acid/alkaline nature of a food as it is the ultimate influence on the dominating Fundamental Homeostatic Control Mechanism that determines systemic pH

    • There is no nutrient that is good for everyone. There is no nutrient that is bad for everyone. Whether a nutrient is good or bad, or whether a nutrient (or food) should be employed for a certain condition does not depend on some inherent quality of the nutrient, but rather on the ultimate effect of the nutrient on the dominant fundamental homeostatic control system in the given individual's Metabolic Type. [For example, antioxidants for someone with an aerobic imbalance (oxidation out of control) would be "good" by contributing to resolving the imbalance. But antioxidants employed on someone with an anaerobic imbalance (such as someone with anabolic/anaerobic cancer lesions) could prove deadly!]

  21. When adversities or imbalances occur, they originate from a certain level—spiritual, mental, emotional, structural, biochemical, physical, environmental and at the systemic, organ, tissue, cellular, nuclear, subnuclear levels. Thus, because:

    • Any given problem may arise from opposite biochemical imbalances in different Metabolic Types (two different Metabolic Types could have the same disease), and ...

    • Nutrients may behave differently on different levels (calcium is catabolic at the cellular level and anabolic at the tissue level), and ...

    • Any given nutrient may have opposite influences in different Metabolic Types (potassium is alkalinizing in an Autonomic Dominant and acidifying in a Carbo-Oxidative dominant), ...

  22. . . . Without identifying the level of origin of a problem through understanding one's Metabolic Type, predictable, reliably effective nutrient selection may not be possible.

The Healthexcel System of Metabolic Typing® does not treat disease , but rather seeks to provide each individual metabolism with everything it needs to build health and balance body ecology through properly evaluating, identifying and addressing each person's biochemical individuality, thus unleashing the body's natural, inherent and powerful capabilities for restoration, rejuvenation, and radiant good health, programmed into every one of the body's 37 trillion cells—a state far beyond that of merely being free of symptoms.

End Notes

[1] Metabolic Type® The sum total pattern of all genetically based strengths and weaknesses, as influenced by nutrition, lifestyle, and environmental factors, as expressed in the myriad of physical (external and internal), psychological (mental, emotional, behavioral, personality), diet-related, and functional characteristics through the Fundamental Homeostatic Controls, that define biological, biochemical, and metabolic individuality and thereby dictate individual responses to and requirements for nutrition as well as therapeutic protocols to unfold full genetic potential and manifest optimal health.

[2] Metabolic Typing® The specific, systematic, testable, repeatable and verifiable methodology and technology developed by Healthexcel for the analysis, evaluation, interpretation and understanding of objective indicators and "body language" (the body's means of communicating through the myriad of physical, mental, emotional and behavioral characteristics, its energy status, i.e., the state of biochemical and metabolic functional efficiency and homeostasis of the body's cells, organs, glands and systems) through which an individual's specific responses to and requirements for nutritional substances may be known to create an individualized Metabolic Type Ecological Lifestyle Program to meet all genetically based requirements as well as eliminate all stressors and blocking factors that undermine function of the Fundamental Homeostatic Controls, to:

  • Determine one’s Metabolic Type®
  • Restore Functional Efficiency
  • Achieve Peak Performance
  • Obtain Optimal Health
  • Unfold Full Genetic Potential.

[3] 37 Trillion is an extraordinarily large number when considered as the number of cells that comprise the human body. What an amazing logistical challenge to supply nutrients and oxygen to every one of those cells! To get just a sense of the situation, imagine if you will, 37 trillion seconds of time in place of 37 trillion cells in the body. If you started right now marking off seconds until you came to 37 trillion, do you know how much time would have passed, by the time you ticked off 37 trillion seconds? ...
37 trillion seconds=1.17 million years!

[4] Dualistic, diphasic Fundamental Homeostatic Mechanisms We live in a "relative" universe, where every action must have an equal and opposite reaction. The play and display of all universal activity is through the interplay of opposites: up/down, wet/dry, fast/slow, north/south, forward/backward, left/right, night/day, hot/cold, creation/destruction, protons/electrons, dark/light, cohesion/adhesion, centrifugal/centripetal, positive/negative, anion/cation, anabolic/catabolic, acid/alkaline, etc. This relative dualism manifests in human metabolism at every level of hierarchical organization, as well as in the fundamental homeostatic controls that regulate every aspect of metabolism. It is through the proper and balanced operation of dualistic, fundamental, homeostatic control mechanisms that physiological, biochemical, and metabolic balance and efficiency are maintained.

[13] Constitutional Elements. The significance of the constitutional elements of foods relative to the constitutional elements of individual metabolism is drawn from Ayurvedic and Chinese medicine. This consideration of metabolic individuality does not concern specific balances of vitamins and minerals. Rather, it pertains to the proper application of herbs and foods. For example, nature always provides more than one herb for any given condition. But, if an herb of a certain constitutional quality is prescribed, say, for insomnia, for someone of the same constitutional quality, that quality will be intensified (the constitutional imbalance will be worsened) and the desired result will be lacking, overshadowed by exacerbation of the constitutional, the more fundamental imbalance. All the ancient systems of medicine recognized the wisdom of treating the person who has the disease over the disease that has the person.
