Weight and Body Fat - How does it work?
While body fat can be measured in many ways, the method used in your scale is bioelec-
trical impedance. This indirect method of determining body fat starts when a safe and
very low electrical current is sent through the lower half of the body. The electrical current
flows more quickly through water and muscle than it will through bone and fat. The scale
measures the speed of the current. Based on this number, the scale estimates body fat
using a multi-step, mathematical formula.
Is it accurate?
Measurements of body fat tend to fluctuate a lot more than simple weighing, and dif-
ferent methods of estimating body fat yield very different results. Just as different scales
give different results, different body fat analyzers can provide very different body fat
estimates. Even with the same scale the numbers will vary because:
• Weight loss tends to produce substantial, continuous, and unpredictable changes in
body water content. Because body fat analysis is determined by water content in the
body, results can vary considerably from day to day.
• Hydration status affects body fat results. If you’ve just worked out, there is less water
for the electrical current to flow through. This may result in a higher body fat result.
In the same way, if you measure your body fat after drinking a lot of fluid, it may
appear that body fat is lower than it really is.
• Skin temperature can have an influence also. Measuring body fat in warm humid
weather when skin is moist will yield a different result than if skin is cold and dry.
• As with weight, it is better to track trends over time than to use individual daily results,
when your goal is to change body composition.
• Results may not be accurate for persons under the age of 16, or persons with an
elevated body temperature, diabetes or other health conditions.
What you need to know!
• Percent body fat refers to the number of pounds of fat divided by your total body
weight and multiplied by 100.
• During weight loss, percent body fat doesn’t appear to be reduced as quickly as
expected because total weight loss and total body fat are decreasing at the same time
(for a more detailed explanation, see next section).
• Weight loss in the form of body fat and lean tissue (muscle) is common, and is
normal.
• To minimize the loss of lean tissue, include regular physical activity, especially strength
training, in your weight loss plan.
Why do I lose weight but my body fat percentage doesn’t change much?
Most body fat monitors show body fat as a percentage only. This body fat monitor shows
you not only a percentage but the actual number of body fat pounds (in fact, this is the
measurement you see after your weight is displayed). Why is that important? When
you lose weight, both the numerator (pounds of body fat) and denominator (total body
weight) go down, so when it’s calculated as a body fat percentage, the number can
be small. For example, a person may weigh 200 pounds and have 40% body fat (= 80
pounds of body fat). He/She loses 20 pounds, but the body fat has only dropped 4% to
36%. That 4% of body fat was 16 pounds of fat – a very significant amount! So do not
be overly concerned if you do not see the percentage change quickly as you are losing
weight: monitor the absolute number of body fat pounds lost. Remember, to minimize
the loss of lean tisse, include regular physical activity, especially strength training, in your
weight loss plan.
BMI
BMI stands for Body Mass Index, a statistical term derived from height and weight. It is
closely linked to body fat and health outcomes. Over 50 organizations, including the US
Government and the World Health Organization, have adopted BMI guidelines. BMI is
inversely related to fitness, meaning that the higher you BMI, the less likely you are to be
fit. Every time your body fat monitor reads your weight and calculates your body fat, it
also calculates your BMI. Along with you weight and your body fat measurements, the
BMI reading gives you yet one more tool to monitor your health and fitness.
General guidelines for BMI are as follows:
BMI less than 19: underweight
BMI 19-25: healthy weight
BMI 25-30: overweight
BMI over 30: obese
BMI Levels
In order to make your body fat and body water readings more accurate, your
monitor automatically calculates a BMI Level for you, based on the personal data you
have entered, as well as measurements the scale takes. Why is that important?People
with different BMIs have differences in muscle mass and body water levels. Do not be
alarmed if you do not see rapid changes to your category level: generally, your level
will change as you lose weight and become more fit. These changes happen gradually,
though, and you may not see them reflected for a few months of consistently following
a diet and exercise regimen.
Make the most of it!
To summarize, make the most of the body fat analysis feature by:
• Tracking change over time and not day to day.
• Using the same scale as much as possible.
• Being extra-consistent in the time of day, day of the week, time before or after food
and fluid consumption, before or after exercise, etc., when measuring body fat
composition.
Always keep in mind that you know your body best. The following ranges
of Body Fat Percentages are offered as guides:
Healthy Range
of Body Fat
Age Females Males
Percentage Body Water/Hydration Levels:
According to the World Health Organization (WHO, 2001), the percentage of body water
should lie within the following ranges:
Women: 50-55%
Men: 60-65%
Children: 65-75%
While a scale/body fat monitor can be a useful tool on your weight-loss journey,
it’s not in and of itself a program for losing weight. Studies show that people
lose three times more weight on Weight Watchers than they do on their own.*

Important Information Concerning
Weight Management
Your Scale is the best tool for monitoring weight. While not the only measure of weight
loss, scales are the most popular method used to gauge weight-loss success. A scale
measures the sum of your total body weight, which includes bone, muscle, fat,
and water.
Body weight fluctuates during the day, and from day to day, depending on a
variety of factors.
• Salt and carbohydrate intake can affect the body’s water retention.
• A large meal adds weight and can cause water retention.
• Dehydration from exercise, illness, or low fluid intake can result in weight loss.
• Muscle is also a factor. Heavy-duty resistance training can build muscle, which
can affect weight.
• The menstrual cycle can cause temporary weight gains and losses.
When You’re Losing Weight
It’s important not to put too much stock in the exact number on the scale, because it can
and will vary. This is especially true when you’re dieting. Small weight gains and losses
are common as your body adjusts to fewer calories and more exercise. Your scale is a
valuable tool when used to track weight over a period of weeks and months. Be aware
that different scales often give different results. The scale at your doctor’s office may
show one weight, and your scale at home another. So don’t get too caught up with
a single number.
Don’t Overdo It!
A surefire way to get overly concerned with your weight is to weigh yourself too often.
We generally recommend weighing yourself no more than once a week when you’re
dieting. Though it’s hard to stick to this pattern, it’s the best way toprevent unnecessary
concern with normal weight fluctuations, which are unrelated to your weight-loss ef-
forts. Regardless of your weighing habits, it’s important that you’re consistent.
Here are 5 rules for effectively monitoring your weight – weigh yourself:
To keep track of your weight, record only one number for the week.
This will give you a clear picture of any trend your weight is following.
When You’re Maintaining Weight
Fluctuations in day-to-day weight tend to be smaller when weight is stable, so a more
frequent weigh-in pattern is helpful. To maintain a stable weight:
• Weigh yourself more often than once a week.
• Use the “5-pound rule” – research shows that people who keep weight within a
5-pound range are more likely to maintain a healthy body weight over the long term.

Facts You Should Know
Your Weight Watchers scale is a precise measuring instrument that is most accurate
when weighing a stationary object. To ensure readings that are 99% accurate, always try
to stand on the same area of the scale platform and DO NOT MOVE. Should the weight
on the scale exceed the scale’s capacity, you may see an error message ”ERR”.
Electronic sensors are sensitive. Be careful not to drop or jar the scale. Place it gently onto
floor surface, and store where it will be protected from impact. The scale is an electronic
instrument and should never be submerged in water. Clean with damp cloth and/or glass
cleaner.
In the unlikely event that the scale battery malfunctions and needs to be replaced, lift
the snap-on battery cover on the bottom of the scale and replace the old battery with a
3V lithium battery (CR2032). Dispose of the old battery properly. Do not attempt
to open the scale or to remove any components. Servicing should be done by
qualified technicians only. See warranty information.
