Scientist from Oxford University, mathematician Nick Trefethen invented an alternative to body mass index (BMI), writes The Daily Mail. In his opinion, people low growth have more pounds than they should, and tall people have no predisposition to obesity, as indicated by BMI.

The body mass index equal to 18,5-24,9 points is the norm. If the index is less than 18,5 - the person is the problem with insufficient weight index from 25 to 29.9 means that people suffering from overweight, and an index of over 30 indicates obesity.

To learn BMI, it is necessary to conduct a simple mathematical calculation: the individual's body weight in kilograms divided by the height of the person in meters, built in the second degree.

Mathematician offers multiply the weight, measured in kilograms, 1.3, and then the result must be divided by the height of a man, pre-multiplied by 2.5. In the end, it turns out that the owners of a large growth minus one from BMI, those with low growth get the unit to their BMI.

By the way, talking about the unreliability of the methods for calculating BMI is already underway for a long time, because, according to many experts, he is not able to reflect the real situation. For example, the BMI of a person may be within normal limits, but at the same time, it can be observed obesity stomach, thereby increasing the risk of cardiovascular diseases.
