Obesity is a condition in which a person has too much body fat. Historically, a BMI > 25 was considered overweight and BMI > 30 was considered obese.
Revisions to the WHO BMI Classification System
The first suggested revision came in July of 2013 when the American Medical Association supported raising the BMI cutoff for obese from 30 to 35, thereby refusing obesity rates by 42%. Unfortunately, this measure never materialized. However, on October 5, 2016, the World Health Organization decided to give the United States a wake-up call by removing the word "obesity" and replacing it with the word American (see Figure O above).
