We link primary sources - including studies, scientific references, and statistics - within each article and also list them in the resources section at the bottom of our articles. Medical News Today has strict sourcing guidelines and draws only from peer-reviewed studies, academic research institutions, and medical journals and associations. However, this method does still provide a quick and useful clinical tool to assess health risks. Having a high body fat percentage or BMI does not always lead to health problems. There are many limitations to BMI and measuring body fat. For example, fat around the abdomen has higher health risks than fat in other areas. The location of body fat is also relevant to overall health. For example, the BMI of a person with high bone density and muscle mass may indicate they have high body fat.Īlso, BMI cannot assess where fat is in the body. These factors are relevant to overall health and assessing body fat. Although BMI can be used for most men and women, it does. The higher your BMI, the higher your risk for certain diseases such as heart disease, high blood pressure, type 2 diabetes, gallstones, breathing problems, and certain cancers. It makes no distinction between lean muscle, body fat percentage, and bone mass. BMI is an estimate of body fat and a good gauge of your risk for diseases that can occur with more body fat. Using BMI to assess body fat or overall health is another issue. This suggests there may be cultural or racial bias with body fat percentage ideals. These differences raise concerns about whether or not ideal body fat percentages are realistic.Īverage body fat percentages also vary across race and ethnicity. Even healthy people can have unusually high body fat. Note that, in our BMI calculator, the 'Upper Weight Limit' depends on age and sex, so it is not fixed as in other calculators.Assessments of body fat consistently show that people have higher body fat percentages than official guidelines recommend. Here is the BMI Prime formula: BMI' = Actual Weight/ Upper Weight Limit It is a simple modification of the familiar Body Mass Index (BMI) system.īMI Prime is defined as the ratio of a person’s Actual Weight (or Mass) to his Upper Weight (or Mass) Limit of the “healthy weight” range. What is BMI Prime?īMI Prime (abbreviated BMI’) is an index of total body fat content. If your height is 1.7 meter and you weigh 65 kilograms (kilos), your BMI isįinally, BMI = 22.5 kg/m 2 (rounded). Here is the BMI formula in the metric system where weight is in kilograms, and height is in meter: BMI = weight/ (height) 2 Furthermore, our BMI calculator is better than the standard BMI calculator once it includes both sex and age into its algorithm. On the other hand, someone with a light bone structure might be considered of normal weight, even if they have excess body fat.Īlthough some factors like, bone structure and muscle mass are not part of the equation when IMC is calculated, Body Mass Index can be helpful to set limits such as underweight, normal or obese, for individuals who lead a sedentary or "normal" life. You should avoid rapid weight loss, swings in weight, and improper dieting.īMI is solely based on weight and height, so it may be an imprecise indicator (might come out as overweight) of body fat if someone has a large bone structure, athletic build or a large muscle mass. The goal of weight loss should be to improve health. Some research studies have shown that a weight loss of 1 to 2 pounds per week for six months can improve the health of overweight people. This calculator computes appropriately your BMI by using a "redefined overweight and obese BMI thresholds for different gender and age groups", a 2015 study, for people who are more than 16 years old male or female. BMI is also known as Quetelet’s index.īMI is a way to discover if you are overweight, obese, underweight or normal. For most people, BMI is a good predictor of health problems that are linked to excess weight. BMI is a person's weight in kilograms divided by his/her height in meters squared. ![]()
