In other words, RFM was almost as good a gauge of body fat as a specialist bit of medical equipment – and all it needs is a tape measure. Based on data from 3,456 adult patients in the US, the RFM measurements closely matched those taken by a high-tech DXA body scan, widely considered the gold standard for measuring body tissue, bone, muscle and fat. WOMEN: 76 – (20 x height/waist circumference) = RFMĪnd the new calculations seem to stand up, too. MEN: 64 – (20 x height/waist circumference) = RFM Useful information about realistic bmi calculator 2022 to help you understand more about the problem realistic bmi calculator to better optimize your health. To get your new RFM measurement, you measure your height and waist circumference, then plug the figures into this formula: It can flag up potential health issues related to someone's weight, even if it's only a rough guide. That said, BMI has been a useful shorthand for tracking problems like obesity over time and across populations. This figure can then be compared against a chart of healthy weights for each height: a normal BMI is between 18.5 and 25.Įxperts have always admitted it isn't perfect – it doesn't take into account gender differences, it doesn't always accurately reflect muscle mass, and results can be skewed for children and the elderly. To work out your BMI, you divide your weight in kilograms by your height in metres, then divide the answer by your height again. Relative fat mass is a better measure of body fatness than many indices currently used in medicine and science, including the BMI.' 'Our results confirmed the value of our new formula in a large number of subjects. 'We wanted to identify a more reliable, simple and inexpensive method to assess body fat percentage without using sophisticated equipment,' says lead researcher Orison Woolcott, from the Cedars-Sinai Medical Center in California. The researchers say that gives a better idea of whether someone's body fat is at a healthy level or not. In the case of RFM, it's the distance around your waist in relation to your height that counts, rather than your weight. The team of researchers behind RFM say it's more accurate than BMI, and it can also be worked out with just a tape measure – so you don't need a set of scales to calculate it, as you do with BMI.
