A new report noted that body mass index does not provide a nuanced enough assessment of health as it relates to weight

BMI, a widely used measure, has long been criticized for being too simplistic. It calculates obesity based only on height and weight, often misclassifying individuals. For example, athletes with high muscle mass may have a high BMI despite having normal fat levels.

For years, medical experts have defined obesity primarily based on body mass index, which measures stored fat by calculating height and weight, to determine a person’s health risks.

An international team of doctors proposed a new way to define obesity that's not based solely on BMI. Here's what they suggest.

Over 75 medical organisations worldwide have endorsed the new definitions, reflecting a growing consensus for reform.

The way the world defines obesity has been in need of an overhaul, according to some experts, and it could be coming soon thanks to a new set of standards.

However, this classification system assumes that weight alone is a reliable indicator of health, disregarding important variables such as body composition, muscle mass, and bone density. These assumptions are increasingly being challenged, particularly when it comes to diverse ethnic groups.

The number does not capture a person's muscle mass; where on their body fat is stored; or how their race, ethnicity and gender affect health risks.
