Determining body mass index (BMI) for adults is a measurement utilized to gauge body fat based on height and weight. An adult with a BMI of 25 is considered to be overweight, while an individual with a BMI of 30 or greater is considered obese.
Calculating BMI is essential for assessing health risks associated with weight and making appropriate lifestyle changes if necessary. Historically, BMI was developed in the 19th century as a statistical tool to categorize individuals based on their weight and height. Today, it is widely used in clinical settings and public health campaigns to assess obesity and its related health consequences.
