The National Institute of Health (NIH) has now defined BMI to be the deciding parameter to know if you are underweight, normal weight, overweight or obese.

Likewise, a woman measuring 155cm and weighing 59kg would find herself within acceptable range under the old system with a BMI of 24.6, however the new system would class her as overweight at 25.6.For example, a man measuring 190cm tall and weighing 95kgs would have a BMI of 26.3 using the old system, which would class him as overweight, whereas the new system would class him as within acceptable range at 24.8.In that way, short people are misled into thinking they are thinner than they actually are, and tall people conversely believe they are fatter. The main problem with the current method for measuring BMI is that it divides the weight by too large a number for shorter people, and by too small a number for taller people. Traditionally BMI is measured by a person’s weight in kilograms divided by the square of their height in meters – the acceptable range for BMI is between 18.5 and 25. New BMI: 1.3 x weight(kg)/height(m) 2.5.
