Clinical Relevance of BIA
“BIA is a simple in-office test that converts
easily obtained electrical measurements
into information about the patient’s body
composition and fluid distribution ...”
Robert Rakowski DC


STEP 1
Total Body Water/Fat
Free Mass




This marker refers to the
hydration of the patient.
Must be higher than 69%
for a test to be valid.
If <69%, patient should be
put on hydration protocol
and retested in 24-48 hours.
Higher is typically better


STEP 1 (CONTINUED)
TBW/FFM




Percentage of fat-free mass
that is water
Values below 69 indicate
dehydration
Accurate even when subject
is significantly overweight
TBW/Total Weight



Percentage of total weight
that is water
Declines with age
Shows dehydration if person
is significantly overweight.


STEP 2
Phase angle


General indicator of cellular
health
Provides info on cell
membrane potential at the
tissue level

•Lance Armstrong is
monitored with the BIA during
his preparation for the Tour
de France.
•Dr. Jeff Spencer uses a
variety of Metagenics
products to keep his team
leading the world.
Cellular health tends to be
correlated to a person’s phase angle
Lance
Armstrong
Suboptimal


STEP 3
Intracellular Water




Healthy cells maintain their
integrity and hold their fluid
inside
>60% is optimal.
Changes with age
Extracellular Water


Water volume outside of the
body cell mass
Higher values may be
related to fluid retention


STEP 4
Fat Free Mass vs. Fat




Determine the amount of
metabolically active tissue in
the person.
Optimal range depends on sex
and age of person.
BIA can determine both
subcutaneous fat (Love
Handles) as well as visceral fat
found around the organs of
the body.
Advantage over calipers to
assess true health status.


STEP 5
ECM/BCM





Ratio of extracellular mass
(non-metabolically active) to
body cell mass (metabolically
active)
Low value is desirable
Upward shift suggests
imbalanced weight loss.
Downward shift suggests
balanced weight loss.
Use Body Composition
Protocol to shift.


STEP 6
Body Mass Index




BMI correlates with a person’s
health.
Studies show even moderate
BMI shifts mean health
consequences.
Lower is better
Alter using Body Composition
Program.


STEP 7
Basal Metabolic Rate





BMR- is the amount of calories
a person burns during a 24
hour period while at rest.
More lean body mass will
increase the BMR
Higher is typically better.
Each person is very unique
Essential in establishing a
proper body composition
program.
