For example, an older person may have a BMI in the healthy weight range, but if they are completely inactive in their daily lives, they may have significant amounts of body fat. BMI is also affected by factors such as age, gender, ethnicity, muscle and body fat mass, and level of physical activity. BMI differences in adultsīMI cannot be completely accurate as it is a measure of body weight, not an indicator of excess body fat. Because body types, muscle, bone mass, and fat distributions vary from person to person, BMI should be used in conjunction with other measurements and not as the sole method of determining a person's healthy body weight. It is important to remember that BMI is only a calculation that does not take into account body composition. What to consider when interpreting the calculated BMIĪlthough BMI (body mass index) is a widely used and useful indicator of healthy body weight, it has its limitations. It is widely used in the initial diagnosis of healthy weight because it is fast and accurate enough for 90-95% people. Being overweight or underweight can have a significant impact on health, so although BMI is not a completely accurate method of calculating healthy body weight (because the relationship between muscle and fat mass is not taken into account), Doctors use BMI to inform their patients about possible health problems, especially if there is a gradual increase in their BMI, and this is currently the official indicator for classifying people according to their level of obesity.īMI ranges vary by factors such as region and age, and are sometimes subdivided into categories such as very low weight or very obese. In general, the higher your body weight, the more likely you are to suffer from health problems such as obesity, diabetes, heart disease and more. It is widely used in medicine as a rapid indicator of potential health complications. The World Health Organization (WHO) recommends a healthy BMI range of 18.5 to 25 for both men and women. To calculate the body mass index, you need to divide the weight (in kilograms) by the square of the height (in meters). Body mass index indicates whether a person's body weight is healthy in relation to a person's height (height). Although the IBW formula is widely used in clinical settings, it is not a universal criterion for measuring the percentage of body fat and muscle mass, as it is different for each individual.īMI (Body Mass Index) - Indice de Quetelet is a method invented by the Belgian statistician Adolf Kittel (1796-1874) to calculate the degree of obesity in the human body. It is used to determine the correct dose of medication prescribed to patients and to determine body weight in sports. ![]() Ideal body weight (IBW) is a clinical standard that includes biometric variables including height, gender, and age. Third degree obesity - extreme or very severe obesityīasal Metabolic Rate (BMR) is the amount of energy your body spends at rest in a neutral and moderate environment (the digestive system is inactive - after about 12 hours of fasting). Body weight is considered normal if the BMI is in the range of 18 to 25, preferably in the range of 20 to 25. ![]() The body mass index is not suitable for calculating your weight during pregnancy, professional athletes and children under 20 years of age. The body mass index is used as an international unit to measure the weight to height ratio.
