The report released by the team found that North America was facing a severe problem of obesity among the masses and accounted for more than a third of the world's obesity. The high no of motor vehicle usage among people is given as a significant reason behind the obesity.
It has to be remembered that only 6% of world's population live in the super-rich continent.
Asia, on the other hand, which accounts for 61% of the global population has the lowest obesity amongst its masses and only accounts for 13% of the weight of the world due to obesity.
Study also found that Japanese people have a low average BMI (Body Mass Index) but high standards of living among world's population.
According to Professor Ian Roberts, one of the authors of the research paper, Japan could be a model for others.
"The Japanese example is quite impressive. Average BMI in USA in 2005 was 28.7 while it was 22 in Japan in the same year. You can be lean without being really poor, and Japan seems to have pulled that off."
It seems like world has to deal with this obesity problem forthwith without any further delay.
The research is published in the journal BMC Public Health.
