Body Mass Index (BMI) – Health Metric
The Body Mass Index (BMI) is a fundamental metric for assessing whether body weight is appropriate. It is calculated by dividing weight (in kilograms) by height squared (in meters). This index helps determine the risk of diseases related to excess weight, such as obesity, diabetes, cardiovascular diseases, and atherosclerosis. Values exceeding recommended norms indicate a higher risk of developing these conditions. For adults, BMI is interpreted as follows: below 16.0 – starvation, 16.0-17.0 – underweight, 17.0-18.5 – underweight, 18.5-25.0 – normal weight, 25.0-30.0 – overweight, 30.0-35.0 – mild obesity, 35.0-40.0 – moderate obesity, over 40.0 – severe obesity. BMI is not suitable for pregnant women, individuals with high muscle mass (e.g., athletes), and children and adolescents.
The waist-to-hip circumference ratio indicator
WHR (Waist-hip ratio, calculator) - This parameter allows for the determination of the ratio between waist circumference and hip circumference. This straightforward assessment provides data on fat distribution in the body, facilitating the identification of the examinee's body type.
CPM – comprehensive metabolic transformation
Complete Metabolic Transformation (CPM) – (eng. Total Metabolic Rate) determines the daily energy requirement of the organism. This parameter indicates how many calories need to be supplied through food to maintain the current body weight. It consists of the Basal Metabolic Rate (PPM), which covers the energy required for essential life functions such as respiration, digestion, and cardiovascular activity, as well as the Activity Metabolic Rate (PPPM), which accounts for energy expended during physical exertion, movement, and daily tasks. The PPM is a value dependent on body mass, which can only be modified by altering weight. Conversely, the PPPM is influenced by lifestyle, physical activity levels, and dietary intake. The following tools are used for calculations: AMR Calculator The AMR calculator estimates the activity metabolic rate, or the energy consumed during various physical activities. It does not include the basic life processes that are part of the PPM. BMR Calculator The BMR calculator computes the basal metabolic rate, or the energy required to sustain fundamental bodily functions while at rest, such as thermoregulation, respiration, and cardiac function. There are numerous non-invasive methods for determining body composition and energy needs. For more precise results, a dietitian can be consulted to perform specialized measurements, including body weight, fat content, lean body mass, muscle mass, water content, BMI, and PPM.
