Bio-Impedance Analysis (BIA)

Bio-Impedance Analysis (BIA) measures certain parameters in the body relating to the tissue and fluid compartments of the body.  A normal distribution of tissue and fluid in the body is associated with the proper functioning of the body, a normal immune system, and factors associated with cell membrane health, normal aging and longevity.  An abnormal distribution of tissue and fluid in the body can be associated with lowered function on the cellular level, dehydration, loss of muscle mass, body toxicity and premature aging.

The body is electrical in nature and the BIA measures our level of functioning, health, and vitality on the cellular level.  BIA testing is FDA approved.

 

 

Understanding Your Body Bio-Impedance Analysis Results

 

Phase Angle:  Phase angle is an indicator of cellular health and integrity.  A low phase angle is consistent with an inability of cells to store energy and an indication of a breakdown in the selective permeability of cellular membranes.  Cell membranes have a high lipid content therefore this reading gives an indication of your cell lipid status.  A high phase angle is consistent with large quantities of intact, healthy cell membranes and body cell mass.

Fat-Free Mass:  Fat-free mass, also referred to as lean body mass, is the total amount of nonfat (lean) parts of the body.  It consists of approximately 73% water, 20% protein, 6% mineral, and 1% ash.  Lean body mass contains virtually all the body's water, all the metabolically active tissues and bone, and is the source of all metabolic caloric expenditure.

Fat Mass:  This is the total amount of store lipids (fats) in the body and consists of subcutaneous fat and visceral fat.  Subcutaneous fat is located directly beneath the skin and serves as an energy reserve an as insulation against outside cold.  Visceral fat is located deeper within the body and serves as an energy reserve and as a cushion between organs.  Everyone needs a certain amount of fat in their body.  The ideal fat percentage is dependent on age and gender.  A certain amount of fat is necessary for the normal body functioning, and a normal balance of body fat in relation to lean muscle tissue is associated with good health (especially in the aging process).  Excess fat in relation to lean body mass can greatly increase the risk to a variety of serious health conditions and concerns, such as:

A greater muscle mass increases metabolism because muscle require a greater amount of caloric fuel for maintenance.

Base Metabolic Rate (BMR):  This is the number of calories consumed and metabolized at a normal resting state over a 24 hour period.

Body Mass Index (BMI):  This is a measure of a person's weight relative to their height.  Please be aware this classification has limitations as it does not take frame size into account.  

Total Body Water:  Water is contained in lean body mass.  Total body water consists of two compartments-intracellular water (ICW) and extracellular water (ECW).  It is the amount of water contained in the body and is a measure for evaluating basic hydration status.

Intracellular Water (ICW):  This is a measure of the amount of water contained within the cell.  Healthy cells maintain their integrity and hold their fluid inside the cell membrane.  Water is needed inside the cell to hold in water-soluble nutrients such as vitamins B and C.  The optimum amount of water that should be inside the cell differs according to gender and age.  As a general rule, 2/3 of your water should be inside the cell.

Extracellular Water (ECW):  This is a measure of the water outside of the cells.  This water stores some nutrients and also helps to remove waste from inside the cell.  As a general rule 1/3 of your water should be outside the cell.
