Metabolic typing Fundamental Homeostatic Controls (FHC)

  • Metabolic type consists of nine Fundamental Homeostatic Controls (FHC)


This clinical model was initially developed by Francis M. Pottenger, M.D. in 1919

  • All organs and glands in the body are connected to the brain (hypothalamus) via Autonomic Nervous System (ANS)
    • ANS controls involuntary activities of the body (heart rate, blood pressure, digestion, repair, immune systems, etc.
  • ANS has two divisions:  Sympathetic and Parasympathetic systems.

Sympathetic dominance

  • The general action of sympathetic system is to mobilize the body’s resources under stress; to induce the fight-or-flight response. It is, however, constantly active at a basal level to maintain homeostasis.
  • More specific, sympathetic system “dominates”:
    • posterior hypothalamus
    • anterior pituitary
    • thyroid
    • heart
    • adrenal medulla (adrenalin, heart rate)
    • kidneys
    • bladder
    • uterus
    • prostate
    • testes
    • ovaries
    • skeletal system
    • cardiovascular system
    • neuro-muscular system
    • urinary system
    • reproductive system
    • calcium metabolism

Parasympathetic dominance

  • The parasympathetic system is responsible for stimulation of “rest-and-digest” activities that occur when the body is at rest, including sexual arousal, salivation, tearing up, urination, digestion and defecation.
  • More specifically, parasympathetic system “dominates”:
    • anterior medial hypothalamus
    • posterior pituitary
    • parathyroid
    • thymus
    • tonsils
    • paratoid
    • lungs
    • adrenal cortex (cortisol, stress)
    • pancreas
    • liver
    • gallbladder
    • spleen
    • stomach
    • intestines
    • appendix
    • bone marrow
    • digestive system
    • immune system
    • lymphatic system
    • respiratory system
    • excretory system
    • protein metabolism
    • carbohydrate metabolism
    • fat metabolism


First researched by George Watson, Ph.D.

  • Conversion nutrients to energy via glycolysis, Krebs (citric acid) cycle, beta (triglyceride=fat) oxidation
  • Approximately 20% comes from glycolysis and 80% from CAC (Krebs, Citric Acid Cycle)
  • The successful completion of CAC depends on the availability of proper amount of oxaloacetate, is which  carbohydrate metabolism byproduct, and Acetyl CoA, which mostly comes from from beta-oxidation of fats.

Slow oxidizers

  • Slow oxidizers are those whose metabolism is skewed towards more production of Acetyl Co-A from fats than oxaloacetate from carbs.
    • Slow oxidizers need to decrease protein and fat and increase carbohydrates in their diet to slow down Acetyl CoA and accelerate oxaloacetate production
    • Nutrients that stimulate oxaloacetate production (Group 1)
      • potassium
      • magnesium
      • chromium
      • copper
      • iron
      • manganese
      • B vitamins
        • B1, B2, B3 (niacin), B6, C, D, PABA, Biotin, Folic Acid
      • Low fat, low purine proteins
      • High carbohydrate

Fast oxidizers

  • Fast oxidizers are those whose metabolism is skewed towards more production of oxaloacetate from carbs than Acetyl CoA from fats.
    • Fast oxidizers need to increase protein and fat and decrease carbohydrate in their diets to slow down oxaloacetate and accelerate Acetyl CoA production.
    • Nutrients that stimulate acetyl CoA production (Group 2)
      • calcium
      • iodine
      • phosphorus
      • zinc
      • choline
      • inositol
      • bioflavonoids
      • Vitamins A, E
      • B vitamins:
        • B3 (niacinimide), B5 (pantethine), B12
      • High fat, high-purine proteins
      • Low carbohydrate


Was originally developed by Emanual Revici, M.D. in 1940s. Described in his book “Research in Physiopathology as a Basis of Guided Chemotherapy.

  • Catabolic/Anabolic balance is balance between fatty acid (negative polar groups)  and sterols (positive polar groups).
  • In a wide sample of the population with out chronic disease, the urine pH will fluctuate around a median of 6.2

Determining imbalance by urine ph

  • Measured at 8 am, 1 pm, 5 pm, 9 pm for three days
    • Too Anabolic – urine pH consistently below 6.2
    • Too Catabolic – urine pH consistently above 6.2
  • A healthy person’s urine will have approximately 50% of their readings above, and 50% below, 6.2 pH, not counting readings that are at or very near 6.2 pH.
  • Revici found that his sickest patients were the ones whose urine pH deviated the furthest from the balance point and were the most consistently in one direction or the other.
  • Acidic is referring to urine pH below 6.2 pH, alkaline is for urine pH above 6.2
  • In more severe cases the imbalance can be spotted in the first day – or even the first test.
    • For instance, an 8am alkaline reading or a 9 pm acidic reading, especially if they are severe, would be a strong indication of the particular imbalance.
    • That is, a 5.5 pH at night or a 7.0 pH in the morning would be examples of strong imbalances.

Anabolic imbalance

  • Excess of sterols to fatty acid.
  • Results in a loss of selective membrane permeability towards a decrease in permeability
  • It is characterized by a shift into anaerobic metabolism (fermentation)
  • Results in acidic tissues and body’s systemic alkalinity as a defense against tissue acidity
  • Clinical indicators of anabolic imbalances are:
    • high cellular potassium
    • low cellular calcium
    • high urinary surface tension
    • low specific gravity
    • low urine ph
    • low sedimentation rate
    • low indican
    • high eosinophils
  • Some symptoms of anabolic imbalance are:
    • osteo arthritis
    • hypertension
    • constipation
    • tachycardia
    • increased oxygen capacity of blood
    • somnolence (drowsy increased sleepiness)
    • increased (higher output) urination (polyuria)

Catabolic imbalance

  • Access of fatty acids to sterols
  • Results in a loss of selective membrane permeability towards an increase in permeability
  • It is characterized by a shift into aerobic metabolism, resulting in out-of-control oxidation with excess of free radicals and peroxide formations
  • Results in alkaline tissues and body’s systemic acidity as a defense against tissue alkalinity
  • Clinical indicators of anabolic imbalances are:
    • low cellular potassium
    • high cellular calcium
    • low urinary surface tension
    • high specific gravity
    • high urine ph
    • high sedimentation rate
    • high indican
    • low eosinophils
  • Some symptoms of anabolic imbalance are:
    • rheumatoid arthritis
    • hopertension
    • diarrhea
    • bradycardia
    • decreased oxygen capacity of blood
    • insomnia (loss of sleep)
    • decreased (low output) urination (oliguria)

Blood type

Developed by Dr. D’Adamo

  • Lectins are small proteins found in small quantities in about 30% of our food
    • Although cooking and digestion inhibit the activity of lectins, some do find their way into the boodstream
    • Certain kinds of lectins will bind to certain kind of blood cells – A, B, O or AB
    • This will cause agglutination (clumping) and further destruction of blood cells
    • Lectins are blood specific and each lectin causes problems for people with only certain blood type
  • Lectins can interfere with digestion and absorption and cause:
    • nutrient deficiencies
    • food allergies
    • IBS (inflammatory bowel syndrome)
    • Diabetes mellitus
    • theumatoid arthritis
    • psoriasis
    • infertility
    • intestinal gas
    • immune deficiencies
    • fatigue
    • headache
    • achiness
    • diarrhea
    • irritability
    • anemia
  • According to metabolic typing author’s clinical experience (William Walcott) blood typing is more about what foods to avoid than what food to eat. Even the developer of blood typing diet abandoned his system in favor of Genotype diet.
