Body Composition Analyzer

Understanding your body composition readings:  This analysis includes a number of measurements providing an in-depth look at your body composition.  We can use this analysis to assess your current health, and to develop a fitness and nutrition program that, over time, will maximize our health.


Body Mass Index (BMI)

BM is a standard height to weight ration useful for classifying risks associated with weight gain.  The World Health Organization (WHO) classification has been developed using the following grading system that links increases in BMI to increased health risks.

BMI                                         WHO Classification

18.5-24.9                                 Healthy Weight

25.0-29.9                                 Overweight

30-40                                       Obese

40+                                          Extreme Obesity

Fat %  -  Body fat is vital to daily body functions.  It cushions joint, protects organs, helps regulate body temperature, and stores vitamins.  However, serious health risks are associated with both too much, and too little body fat.  By design, women's bodies require a higher percentage of body fat to be healthy.

BMR -  Basal Metabolic Rate reflects the amount of calories used by the body to maintain normal functions when at rest.  Daily activities and exercise increase BMR by approximately 15%.  BMR helps you establish just how many calories your body needs in a day to achieve proper energy balance.

Impedance - Measure in Ohms, the Impedance value reflects the strength and speed of an electrical signal traveling through the body.  Muscle is the signal's motorway, and fat mass is like a traffic jam.  More muscle means it's easier for the signal to pass through your body, resulting in a lower impedance value and % body fat.  consistent conditions and stable hydration status are not only healthy, but will also yield consistent results.

FFM  -  Fat Free Mass is everything in the body that is not fat;  muscle, water, bone connective tissue, etc.  Muscle acts as the body's natural "fat-burning engine", therefore it is important to maintain or even gain healthy muscle mass when exercising or dieting.

TBW  -  Reflects Total Body Water.  It is important to ensure your body is not dehydrated, especially when exercising or dieting.  Enter your TBW below, and compare your hydration level to healthy averages:    

  _______/________ x 100 = ________________________                       Note:  Individuals who are severely dehydrated may receive an inaccurate measurement.

TBW         Weight               Estimated Hydration Level %                          Female:  50-60% hydration                       Male:  60-70% hydration


Desirable Ranges  -  Everyone needs fat.  These healthy ranges display how much you should have in term of %, and weight.  Research shows that individuals with appropriate amounts of fat are less likely to develop obesity-related health conditions.

Target Body Fat %  -  Set a realistic goal for body fat %.  Tanita calculates the approximate amount of fat mass, not just overall weight, but specifically fat mass that needs to be lost in order to achieve the pre-selected weight.  Always try to maintain FFM (muscle) when dieting.  The target feature is an estimation only.
