Body Mass Index (BMI) is an important tool used to determine if a person is underweight, overweight, or at a healthy weight. It is calculated based on a person's height and weight, and is used by healthcare professionals to assess an individual's risk of various health conditions.。

The normal range for BMI is between 18.5 and 24.9. A BMI below 18.5 is considered underweight, while a BMI above 24.9 is considered overweight. A BMI of 25 or higher is classified as obesity.。

There are several factors that can affect a person's BMI, including age, gender, muscle mass, and bone density. For example, athletes and bodybuilders often have a higher BMI due to their increased muscle mass. However, this does not necessarily mean that they are overweight or at risk of developing health problems.。
