Does the Body Mass Index need fixing?

ID-10060024

The body mass index (BMI) was created 150 years ago in order to analyze weights of people grouped by their different heights.  In order to calculate BMI you take your weight in kilograms and divide it by your height in meters squared.  The BMI has been criticized due to its inability to  tell the difference between someone’s body fat and muscle.  Nick Trefethen, a mathematician and Professor of numerical Analysis at Oxford University is one of the BMI critics who developed a new formula to calculate an individual’s BMI which is 1.3 x weight divided by height to the power of 2.5.  Visit the site to calculate both your old and new BMI.  What do you feel is the most accurate way to determine if an individual is “overweight”?  Do you feel that the old method of calculating BMI is outdated?
