Muscle Mass %
Knowing our muscle mass percentage is useful if we are undergoing any changes in our exercise regime or
undertaking a program of weight loss. Lean muscle mass may decrease by nearly 50% between the ages
of 20 and 90. We can replace this loss with fat if we don't maintain our exercise levels. We can also lose
muscle rather than fat if we undergo starvation-type diets, which are not recommended. At rest, the body
burns approximately 50 additional calories for each pound of muscle gained. So if we come off a starva-
tion-type diet, we actually put on more weight as fat. Ideally we want to maintain our muscle mass % while
reducing fat %.
Hydration %
Water is a vital element in the majority of the body’s functions and can be found in every cell, tissue, and
organ. A healthy hydration % needs to be maintained to operate at maximum efficiency. Hydration levels
fluctuate throughout the day, so use this measurement as a guide and not your absolute. Also note that
eating large meals, consuming alcohol, menstruation, illness, exercising and bathing may cause variations
in your hydration level. Optimal hydration % for Women is 45-60% and for Men is 50-65%.
Body Mass Index (BMI)
Body Mass Index (BMI) is an index of weight-for-height that is routinely used to classify underweight, over-
weight and obesity in adults.
Visceral Fat (%)
Visceral Fat is located in our abdominal cavity (stomach area) and surrounds our vital organs. The more
visceral fat you have the greater the chance of developing insulin resistance (leading to type 2 diabetes),
heart disease and high blood pressure.
The Wireless Body Analysis Scale gives a visceral fat percentage for reference. Visceral Fat percentage
between 1% and 9%: Indicates that you have a healthy level of visceral fat.
Visceral Fat percentage more than 9%: Indicates that you could have excess visceral fat and you may wish
to consider modifying your diet or increasing your exercise levels.
Bone Mass (lb)
Similar to MUSCLE MASS percentage, understanding changes in our BONE MASS (lb) can be useful,
especially during weight reduction programs.
