On the day after celebrating its independence and with likely half the nation suffering from over-consumption, we thought it appropriate to 'celebrate' another #winning rank by the US. At an average of 181.27lbs (gender-weighted!), Bloomberg finds that the US is the 'heaviest' nation on earth.
Bloomberg ranked countries based on the weight of an average adult, which is the gender ratio-weighted aggregate of male and female adults.
Methodology
Weights were calculated by adapting the standard BMI formula: BMI = (weight in pounds / (height in inches x height in inches)) x 703. BMI is an index of weight-to-height used to classify underweight, overweight and obese adults. Average adult BMI data were collected from the World Health Organization.
