Body mass index (BMI) is a measure of body fat based on height and weight that applies to adult men and women. It’s used to categorize individuals as underweight, normal weight, overweight, or obese. For example, a BMI of 25 or above indicates overweight, while a BMI of 30 or above indicates obesity.
BMI is a widely used metric for assessing weight status and related health risks. It has been instrumental in tracking obesity trends over time and designing public health interventions to address the global obesity epidemic.
