Body water measurement results are influenced by the proportion of body fat and muscle. If the
proportion of body fat is high, or the proportion of muscle is low then the body water results will
tend to be low.
It is important to remember that measurements such as body weight, body fat and body water are
tools for you to use as part of your healthy lifestyle. As short term fluctuations are normal, we suggest
you chart your progress over time, rather than focus on a single days reading.
Basal Metabolic Rate (BMR) - What does it mean?
Your Basal Metabolic Rate (BMR) is an estimation of the energy (measured in calories) expended by
the body, at rest, to maintain normal body functions. This continual work makes up about 60-70% of
the calories the body uses, and includes the beating of your heart, respiration, and the maintenance of
body temperature. Your BMR is influenced by a number of factors, including age, weight, height, gender,
dieting and exercise habits.
