Which country is 'heaviest' in the world?

European researchers have calculated the weight of all humanity on Earth and published a list of the 10 most 'heavy' countries in the world with the top position belonging to the United States.

According to Live Science, based on data collected around the world for 2005, researchers used body mass index (also known as BMI) and classified. height to estimate the average body weight of an adult. Then they multiply these results with the population to get a total body weight.

Globally, the average body weight or weight of an adult is 62kg. Therefore, the total weight of all adults on Earth is 316 million tons.

Comparing with the BMI> 25 threshold for overweight and BMI> 30 for obesity, the team calculated that all adults in the world have a total overweight of 17 million tons (equivalent to with a payload of about 170 military aircraft carriers) and the weight of obesity is 3.9 million tons.

With the calculation results, the team also published a list of the 10 most 'heavy' countries and the 10 most 'light' countries in the world based on the total weight of each country's population in 2005.

The United States tops the list of 'heaviest' , while the top 'light' category belongs to countries in Africa and Asia, of which Vietnam ranks 9th.

Representatives of the study authors said that their goal is to raise public awareness about the effects of population growth.'The United Nations predicts, by 2050, our planet will have 2.3 billion more people. Ecological consequences from population growth will be exacerbated by an increase in the average body weight or body weight of each individual, ' the research report published in the journal BMC Public Health.

The above conclusion is based on the following argument: Increased body mass will require more energy to maintain and move. Therefore, when someone's weight increases, they also need more calories to survive. This means increasing demand for Earth's resources.

'Solving the problem of obesity of the population can be vital to food security as well as the ecological sustainability of the world,' the team said.
