Body Mass Index (BMI) is a numerical value derived from an individual’s weight and height, used as a screening tool to categorize a person’s body weight relative to their height. It helps to identify whether an individual has a healthy body weight, is underweight, overweight, or obese.
How BMI is Calculated:
The formula for BMI is:
Alternatively, in pounds and inches:

BMI Categories:
- Underweight: BMI < 18.5
- Normal weight: BMI 18.5–24.9
- Overweight: BMI 25–29.9
- Obesity: BMI ≥ 30
Uses and Limitations:
- Uses:
- It is a simple, quick, and inexpensive method to assess body fatness and categorize weight status.
- Helps in identifying individuals who may be at risk of health problems due to their weight.
- Limitations:
- Does not differentiate between muscle and fat mass, which can lead to misclassification in athletes or muscular individuals.
- Does not account for age, sex, or fat distribution.
- May not be accurate for all ethnic groups or for children and the elderly.
Despite its limitations, BMI is widely used as a general indicator of health related to body weight
