The Inbody composition analyzer is able to measure what proportion of body weight is water (normally 60%), protein (indirectly measuring muscle mass), minerals and fat.
Body weight = total body water + protein mass + mineral mass + body fat mass
This then allows for a muscle: fat ratio to be calculated.
100% normal weight refers to the weight of a person given their height, referred to as BMI (body mass index).
BMI = weight (kg)
Healthy BMI range between 18.5kg/m² - 24.9kg/m²
100% normal skeletal muscle mass refers to the ideal quantity of skeletal muscle mass for a person’s standard weight.
100% normal body fat mass refers to the body fat mass that a person should be for a person’s standard weight.
