Biochemical Types by Dr. Fuller-Looney

Posted by Alexander Harper on




What exactly are Biochemical Types?  This refers to different types of biochemical actions that take place in four different human categories.  A Biochemical action refers to the chemistry of the body such as signaling, energy, metabolism and digestion of foods and what the body does with its nutrients and protein. These types are not related to nationality, race or diet.

Why would we be different types?  This takes place even within families.  To best explain this you would first need to know that at the time of conception when you are even yet an embryo you are given an individualized workbook.  This workbook is coded in your genetic material.  Your embryo has an estimated 20,000 to 25,000 genes carrying 3 billion bits of genetic information
that makes up your instruction book.   For the rest of your life, nothing new will be added to this makeup, only nutrition and oxygen.  Anything happening in a living body, the proteins are either making it happen or regulating it as in biochemical processes.

Dr. Lewellys Baker of John Hopkins believes that we are born with a dominant gland that influences our body’s biochemical functioning.  Your dominant gland determines differences in body chemistry balance, metabolic function, and energy usage.  Your glandular type, like your structure, is programmed by your genes.  Your glandular type affects your body’s usage of basic micronutrients – air, water, protein, fat, and carbohydrates, along with micronutrients such as vitamins and minerals – they create the energy and building materials necessary for cellular regeneration.  Each person has slightly different ways of using these raw materials and needs different relative amounts of them: some require more protein; others need more fat or carbohydrates.

How long have we known about this typing?  Let us review some of the work that has been done on body types to date.  This has been work started and improved upon by many doctors, scientists and health practitioners.  My favorite professor (now deceased) Dr. Roger J. Williams who coined the name “Biochemical Individualism” is the one who gained my interest in the 1960s.   I have tired to take it to another level for the last thirty some years of my practice by using scientific processes and imaging on the DXA.  The body skeletal, fat, fluids, and muscle of the individual can be measured and further assed through blood, urine and saliva for profiling.  The Egyptians and India (Ayurvedic) taught on it for more than 5000 years.  You have heard the statement, “what works for one person does not necessarily mean it will work for you”.

What are the names of the different types?  I refer to them as numbers to keep it simple but there is a major gland connected to each type.

  • Type One depicts thyroid or parathyroid type
  • Type Two depicts gonad or hormonal type
  • Type Three depicts adrenal or suprarenal type
  • Type Four depicts neuro (nerves) or pituitary type


Is it true that there are digestive enzyme deficiencies connected to each type?  Let us go back to the fetus and recognize when digestive enzymes come in to being.  It is in the 9th to 12th week the fetus creates its ability to produce digestive enzymes on call.  However, they are not turned on until their own DNA turns them on.

A newborn only makes the digestive enzymes for mother’s milk and this will hold true until they are around 18 months old.  When the teeth come in for chewing and the gut is developed with proper bacteria it is only until they are 36 months before they can breakdown sugars.  I think you can recognize that we give our babies food before they can break them down and this can lead to many complications.  This does not make the types but creates more gut imbalance.

  • Type One portrays poor carbohydrate digestion & requires supplemental carbohydrate splitting enzymes.  There are various carbohydrates in most food and therefore there are many different digestive carbohydrate-splitting enzymes required.
  • Type Two portrays poor fat/lipid digestion & requires supplemental digestive lipase enzymes.
  • Type Three portrays poor protein digestion and requires various supplemental protease enzymes.
  • Type Four portrays poor dairy and starch digestion and requires supplemental lactase and amylase for the sugar and starch splitting enzymes.  They tend to have sensitive stomachs.

We tend to be drawn to or crave the food we cannot properly breakdown.

The most recent research that has come recognizes that we fall into three base type gut microbes called Enterotypes.  These Enterotypes match up to the biochemical types and are not related to race, native country or diet.  Sadly, the numbers of the biochemical types and the Enterotypes do not match. Try not to get confused.

  • Type One – thyroid/parathyroid – carbohydrates problems – Enterotype 3
  • Type Two – hormonal/gonad – fats & starch problems – Enterotype 1
  • Type Three – adrenal/suprarenal – protein problems – Enterotype 2
  • Type Four – pituitary/nerve – dairy & starch problems – Enterotype 1
