How does it work?
While body fat can be measured in many ways, the method used in your
scale is bioelectrical 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 throughbone 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 weigh-
ing and different 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.
