BODY FAT MONITORING SCALE
MODEL #7851
Congratulations! You have purchased a precision health monitoring
product that should provide you with years of accurate use. To assure you
obtain the best performance please read the following set-up and use
instructions carefully before using the scale. A few points to remember as
you get started:
• Open the battery compartment on bottom
of scale. Gently pull out the plastic tab
under the battery. Be sure to check that the
battery is seated properly. If display does
not appear when scale is turned on,
check this first.
•Always weigh in bare feet to obtain health readings – body fat,
body water, muscle mass, and bone mass. If only weight is
desired it is not necessary to weigh in bare feet. ERR will appear
after the weight is shown for the other health readings if you
are not in bare feet. Be sure to stand on scale with feet on the
metal plates.
•Always stand reasonably still. If there is too much movement,
the scale cannot provide accurate measurements.
•Place scale on a hard surface. The scale will not weight
accurately on carpet.
•The scale may not provide accurate measurements for children
under age 7, adults over age 99, and body building athletes
or professional athletes.

INFORMATION ABOUT BODY FAT MEASUREMENT
Body fat scales measure body composition with the Bioelectrical Impedance
Analysis (BIA) technique. The scale offers an estimated body fat percentage
based on how long it takes a small, harmless electrical current to pass through
the body. The more fat the electrical current encounters, the higher the body fat
percentage is, since fat offers higher resistance to electrical currents than muscle.
This is because electrical currents pass easily through the high volume of fluids
that muscle tissue contains. The scale receives the results, which are equal to the
user’s total body density. The scale then plugs the body density figure into an
equation to determine his body fat percentage based on height and weight.
INFORMATION ABOUT BODY FAT
Body fat is an essential part of the body. The fat in your body allows you to absorb the fat-soluble vitamins A, D, E and K. Fat also allows you to absorb substances called carotenoids, which act as antioxidants in your body. Body fat also
aids with body temperature maintenance and insulation. There is a thin layer of
fat directly underneath your skin. This fat layer acts like insulation and helps keep
heat inside the body to maintain body temperature. In addition, a layer of fat also
surrounds your bones, tissues, nerves and major organs, such as your heart and
brain. This layer of fat acts as a protective cushion. If you are exposed to severe
trauma or a sudden impact, the fat absorbs as much shock as possible to protect
these organs from damage.
While some fat is important in keeping your body functioning efficiently, too
much fat can lead to severe medical problems, including heart disease, heart
attack and stroke. The goal of weight loss is to maintain a balanced relationship
between muscle mass and body fat. Please consult your physician for specific
information regarding your health and weight loss plan.
INFORMATION ABOUT BODY WATER
Water is clearly the most important nutrient and the most abundant substance
in the human body. Water comprises more than half of the human mass and is a
major component in every cell. All the cells in the body, including skin, organs,
and muscles can only function if they receive the proper amount of water. Dehydration will degrade a person’s ability to exercise and burn calories, and will reduce protein synthesis which is needed to build or repair muscles. As a guideline,
it is recommended that adults consume 64 ounces of water each day. Our table
on Page 9 should only be used as a reference towards your fitness regime, diet
and fluid intake. As always, please consult your physician.
MORE IMPORTANT INFORMATION

INFORMATION ABOUT BODY MUSCLE
The muscular system is the body’s network of tissues that controls movement
both of the body structures and organs. Without the muscular system, all other
essential functions of the body would not be able to take place. Muscles are
essential to other body abilities as well, including circulation, digestion, and
energy. Building strong muscles is a very important part of your overall health.
When you strength your muscles, you will be able to see and feel the results. In
addition, your body fat percentage will also decrease. This scale is designed to
give you an accurate percentage of your body’s muscle profile.
INFORMATION ABOUT BONE MASS
The human skeleton consists of 206 bones. The bones which form the skeleton
consist of proteins and mineral substances. Whenever the bones meet in the
human body there is a joint formed which performs a special function in the
body. Without bones, the human body would not have a shape. Regular exercise
is necessary to keep fit and to maintain the abilities of the bones efficiently.
Exercise makes the muscles stronger and gives power to the body, all while
keeping problems of the bones away. The bone mass feature of this scale
measures the weight of the bones, or the amount of mineralized tissue in the
bones in your body. Please consult your physician for specific information
regarding your health.
INFORMATION ABOUT HEALTHY EATING
Healthy eating is not about strict nutrition philosophies, staying unrealistically
thin, or depriving yourself of the foods you love. It’s about feeling great, having
more energy, and keeping yourself as healthy as possible– all of which can be
achieved by learning some nutrition basics and using them in a way that works
for you. Healthy eating starts with learning how to “eat smart”—it’s not just what
you eat, but how you eat. Learning the habits of healthy eating can boost your
energy, sharpen your memory and stabilize your mood. You can expand your
range of healthy food choices and learn how to plan ahead to create and
maintain a satisfying, healthy diet.
