"People are fattier"

In the late '90s, the World Health Organization introduced a new assessment of obesity, the so-called Body Mass Index (BMI). This is obtained by dividing weight (in kilograms) by the square of height (expressed in meters). According to this index value of 25 shall be construed as obesity and a value of 30 is already required medical intervention. Before the system was available, according to which body weight should represent, body height, minus 1 meter - with a margin of error of 10%. So, who is 1.75 meters tall, can weigh up to 82.5 kg. Currently, according to BMI, who would have a value of 27 is considered overweight. Critics consider this index as too strict, too little arbitrary and does not take into account factors such as age and body constitution.
