World's fattest countries revealed: Where does America fall on the list? - New York Post

Statistics were based on body mass index (BMI) — specifically, people who were underweight, overweight or obese.

The map revealed that 39% of the world’s adults were overweight or obese — and 68% of Americans fell into those categories.

On the other hand, Vietnam is ranked as the skinniest nation — with just 18.3% of the people in Southeast Asia being considered overweight or obese.

Vietnam – 18.3% India – 19.7% Bangladesh – 20% Ethiopia – 20.9% Nepal – 21% Timor – 21.6% Cambodia – 21.7% Eritrea – 22% Niger – 22% Burundi – 22.2%

People who are overweight or obese have an increased risk of many health conditions including death, stroke, cancer and high blood pressure, according to the CDC.

A recent study also suggested that obesity should be classified as a brain development disorder rather than a behavioral disease.
