How is obesity measured?

In basic terms, obesity occurs when “energy in” is greater than “energy out”. However, obesity in most cases is caused by a combination of factors, such as, genetic, neuroendocrine, environmental, and metabolic issues. Multiple methods of measuring obesity exist. The most commonly used method in medicine is the Body Mass Index (BMI). The formula for the BMI is: weight (kg)/height squared (m2) Since in this country we use pounds and feet, our BMI calculator is available for you. The World Health Organization (WHO) has developed a classification to help numerically define obesity based on BMI.

Who Classification BMI
Ideal Weight 20-24.9
Overweight 25-29.9
Moderate obesity (class I) 30-34.9
Severe obesity (class II) 35-39.9
