A fascinating interactive map published by Our World in Data, which users of the MailOnline app can view by clicking here, shows the huge disparity in obesity rates.

The data comes from a 2016 collection of figures from 195 countries around the world.

It found that more than a third, or 39 percent, of the world’s adults are overweight or obese.

Around 64 per cent of Britons and 68 per cent of Americans are also obese, the figures show.

The statistics come from the NCD Risk Factor Collaboration, which recorded global trends for 128.9 million people between 1975 and 2016.

It looked at data on body mass, specifically the number of people who are underweight, overweight or obese.

No country saw a decline in obesity rates during that period, according to data published by Our World in Data.

All ten of the world’s fattest nations are located in the Pacific Ocean, and the island of Palau has the second highest number of overweight or obese adults at 85.1 percent.

It was followed by the Cook Islands, the Marshall Islands and Tuvalu, which recorded figures of 84.7 percent, 83.5 percent and 81.9 percent respectively.

Outside the Pacific, Kuwait reported 73.4 percent, placing it eleventh.

In the league table of 195 countries, the USA is 15th, Australia is 25th, and Great Britain is 30th.

Body mass index (BMI) is a measure of body fat based on your weight and height.

Standard formula:

  • BMI = (weight in pounds / (height in inches x height in inches)) x 703

Metric formula.

  • BMI = (weight in kilograms / (height in meters x height in meters))


  • Until 18.5. Underweight
  • 18.5 – 24.9. healthy
  • 25 – 29.9. Excess weight
  • 30 – 39.9. Fat
  • 40+Morbidly obese

Overweight is defined as a body mass index (BMI) of 25 or more, while obesity is defined as an adult having a BMI of 30 or more.

A healthy person’s BMI, calculated by dividing weight in kg by height in meters and the answer again by height, is between 18.5 and 24.9.

Obesity is a risk factor for several leading causes of death worldwide, including heart disease, stroke, diabetes, and various types of cancer.

Type 2 diabetes, which is associated with obesity, can also lead to complications such as heart disease, vision loss, and kidney problems.

According to The Lancet’s 2017 Global Burden of Disease study, 4.7 million people died prematurely in 2017 as a result of obesity.

In the UK, obesity and related illnesses cost the NHS an estimated £6.1 billion a year, with this expected to rise to more than £9.7 billion each year by 2050.

It is also believed to be responsible for over 30,000 deaths in the UK each year.

The Centers for Disease Control and Prevention estimates that obesity costs the US health care system about $173 billion annually.

According to Our World in Data, in 2016, 13 percent of adults age 18 and older worldwide were obese.

In comparison, next to Vietnam, which recorded the lowest rate of overweight or obese people, India reported the second lowest proportion at 19.7 percent.
