You can also set body goals, such as a certain weight or fat percentage by selecting Goals on the
website or in the app. Once a goal is set you can view your progress towards this goal alongside your
other activity data.
If you would like personalised advice regarding your body composition, we recommend consulting a
licensed personal trainer or medical professional.
You can find more information about body composition in this Article - Measuring and Evaluating
Body Composition from the American College of Sports Medicine, as well as other online resources.

Safety and body composition

The current sent through your body when performing a body composition measurement with the
TomTom Touch Fitness Tracker is completely harmless. However, if you are pregnant, have a
pacemaker or other internal medical device, always consult your doctor before use.
Important: Body composition cannot be accurately measured whilst pregnant or if you have larger
metal implants in your body, for example as a result of surgery.

Measuring and Evaluating Body Composition
Jan 11, 2012
Written by Tiffany Esmat PhD
What does the number on the weight scale really mean? In regard to overall health, weight is not
nearly as important as the composition of that weight. More important, rather than tracking
weight, we should be aware of our body composition. Stepping on a weight scale simply tells us the
combined weight of all our body's tissues. That weight may fluctuate throughout the day
depending on the time of day, hydration status or what we are wearing. In contrast, body
composition reveals the relative proportions of fat and lean mass in the body. Fat mass consist of
two types of fat: essential and nonessential fat. The second component of body composition, lean
mass, refers to bones, tissues, organs and muscle.
Essential fat is the minimal amount of fat necessary for normal physiological function. For males
and females, essential fat values are typically considered to be 3% and 12%, respectively. Fat above
the minimal amount is referred to as nonessential fat. It is generally accepted that a range of
10-22 percent for men and 20-32 percent for women is considered satisfactory for good health.
A body composition within the recommended range suggests you have less risk of developing
obesity-related diseases such as diabetes, high blood pressure, and even some cancers. In addition,
although we face risks when our body composition is too high, we face another set of risks when
our body composition is too low. When we drop below the minimal recommended levels of
essential fat, we negatively affect the delivery of vitamins to the organs, the ability of the
reproductive system to function, and overall well-being.
How can you determine your body composition? Body composition can be estimated through various
techniques from field-based tests requiring only a calculator or tape measure to advanced tests
conducted in a clinical or laboratory setting performed by a trained technician. Common methods
of exploring the levels of adiposity include body mass index (BMI), waist circumference, skinfolds,
bioelectrical impedance analysis, and the BOD POD.
