Why Measure?
Measuring body fat and
muscle mass before,
during, and after nutrition
and physical training
programs allows for a
benchmark in which to
see a starting point,
progress, provide
guidance, and attain more
effective results.
DEXA scanning provides
extremely accurate
measuring of body fat
along with bone and
muscle mass. The exam is
precise, non-invasive,
accurate and reliable. It is
considered to be the "gold
standard" in the U.S.

Why Measure Body Fat?
Have you ever started a diet and or a
training program only to find your weight
actually does not change or even goes
up? Or perhaps you've had a spa
treatment or a hot jacuzzi and seen your
weight drop?

It is important to realize that although the
Scale may be a good instrument to
measure relative overall changes in your
body weight when you are not making
any major lifestyle changes, it should not
be relied on as a source to direct your
training and nutrition programs. The
reason is that the scale, no matter how
accurate in measuring actual weight,
does not reveal what it is actually
measuring. So, the scale weight shown
is actually a combination of muscle,
bone, and fat mass along with anything
else that's in/on your body.

The problem with relying on the Scale in
directing your training / nutrition program
is that it can give misleading results and,
in turn, provide poor guidance. First, any
given weight can mean different things
for different people -- even people who
are the same height! For example, one
person weighing 150 lbs. and 5'10" tall
might have a body fat percentage of
10%, or 15lbs. fat, and 135lbs. lean body
mass (the mass of the body minus the
fat) and another person the same weight
and height might have a body fat
percentage of 25%, or 37.5 lbs fat.
Clearly, the Scale says these people
(who are the same weight) are identical
and they are not! The person with a 10%
body fat percentage is an athlete and
would need an entirely different diet and
exercise program than the person at
25% body fat (notice we did not say than
the heavier person!).

In another example, after starting a low
impact aerobics and light weight training
program, a person might see their weight
only drop a little and perhaps get
discouraged and stop training. What
might actually be occurring is that they
are losing significant fat mass while also,
at the same time, gaining muscle mass
(and potentially bone mass). The effect is
that the Scale only sees the NET result
on weight and the person has no idea
that they are actually losing much more
fat than they are realizing by looking at
the Scale. In this case, the individual
would have been much better served by
having a DEXA body fat scan done
before starting their new program. A
scan 3 or 6 months later would have
revealed the significant changes in fat,
muscle, and bone mass and provided
increased motivation and direction for
future training.

We advise our clients that before starting
any sort of training / nutrition program
that they obtain a real "snapshot" of
where they are in terms of body
composition: fat, muscle, and bone
mass. Additional "snapshots" can be
captured during the program to help
provide direction and, after a duration,
for example 6 months, to gauge overall

Why Should I Measure My Body Fat

Getting an accurate measure of one's
body fat percentage is one of the most
important things to directing and
measuring any exercise and/or nutrition
program. Imagine going on a long
journey without a Map or GPS and
having to drive with your eyes closed!
That's a good analogy for someone
embarking on a nutrition/exercise
program without knowing his or her true
fat/muscle/bone percentages. And, to
further the analogy, relying on a Scale as
a guide on this journey would be like
trusting a tourist to give you the
directions (see Scale article to right)!

The goal of most nutrition and exercise
programs is to lose fat while at the same
time gain muscle. Optimally, the two
programs work together to maximize this
goal. In order to optimize the program
though, it is vital to see where you are in
terms of body fat percentage and lean
body mass (the mass of the body minus
the fat). The results of the DEXA body fat
analysis will accomplish this and help
determine the proper nutrition and
exercise program. The results can also
determine if a person's weight loss goals
are realistic. For example, if someone
weighs 180 pounds and has a body fat
percentage of only 10%, then their goals
might be more oriented toward muscle
development and endurance than weight
loss. In another example, if someone has
a high body fat percentage, then their
goal might focus on losing fat (see
recommended body fat percentage chart

In summary, testing body fat helps a
person develop appropriate and
targeted nutrition and weight loss goals
to maximize their health. Measuring body
fat analysis by DEXA is the best way to
accomplish this. The results can help you
determine if your nutrition and exercise
program is appropriate by seeing if you
are losing body fat and gaining muscle
mass in the best way possible.

BMI vs. Body Fat %
BMI, or Body Mass Index, is an
appoximation of body fat based
on height and weight. It is a poor
way to measure body fat
compared to an actual Body Fat
measurement using the DEXA.
The reason for this is that BMI
assumes that everyone of a
certain height should be within
the same weight range. This can
be extremely misleading as seen
in the article on this page titled
"Why Trust A Scale". The cases
of two different people of the
same height and weight but
dramatically different body fat
percentages vividly illustrate the
failings of BMI (which sees these
people as equals in terms of
body fat).
Healthy Body Fat %
The amount of fat determined to
be healthy varies based on Age
and Gender according to the
World Health Organization
) and National Institutes of
. The American Council on
provides some other
categories for comparison. Fat
percentages vary depending on
the source, so the numbers
should be used as a general

One thing everyone agrees on is
that there is a certain amount of
Essential Fat which is essential
for body functions such as
regulating temperature,
protecting body organs, and
providing needed energy for the
body. Essential Fat percentages
also vary depending on gender
(male vs. female), with women
requiring a much higher level of
essential fat than men.

Although not a problem for most,
it is very important that any
weight loss goals do not involve
dropping below the person's
essential fat or required fat
