Our team conducts research projects to improve knowledge leading to better management & treatment options. The Centre for Obesity Research and Education (CORE) is always looking for people who are willing to donate their time and participate in studies in the area of obesity. For Chinese, Indian and Malaysian people, a BMI greater than 23 is regarded as overweight and a BMI greater than 27.5 is regarded as obese. In Ethnic Groups: For some ethnic groups the BMI values need to be modified.In children it is better to express weight as a percentile value, in which it is compared to others at the same age and sex. In Children: The BMI can be misleading in children, as body fatness changes over the years as they grow, and girls and boys also differ in their body fatness as they mature.As the index is a calculation of weight and height alone, it assumes that the increase is due entirely to body fat. In Athletes: The BMI can be misleading in athletes (such a body builders) who have a low body fat percentage, but deliver an excessive BMI as they have a significant increase in muscle mass.Use the BMI as a general guide but remember there may be reasons to modify the interpretation and you should discuss this with your doctor if you were concerned. This includes how much energy (calories) you consume through food and how much energy. Your weight is determined by lots of factors. This category of BMI is associated with a higher risk of health conditions, such as high blood pressure, heart disease and certain types of cancer. This means that: very muscular adults and athletes may be classed overweight or obese. Note that, in our BMI calculator, the 'Upper Weight Limit' depends on age and sex, so it is not fixed as in other calculators.Centre for Obesity Research and Education homeīasic Course in Laparoscopic Adjustable Gastric BandingĪdvanced Course in Laparoscopic Adjustable Gastric Banding A BMI score of between 25 and 29.9 is classed as ‘overweight’. The adult BMI does not take into account age, gender or muscle mass. 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 75 inches and you weigh 220 pounds, your BMI isįinally, BMI = 27.5 kg/m 2 (rounded). Here is the BMI formula in the English (Avoirdupois) system where weight is in pounds, and height is in inches: BMI = 703 x ( 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.
