Your body mass index (BMI) number gives you a general indication of whether you are underweight, healthy, overweight or obese. The BMI is calculated based on your height and weight.
Listed below are the possible categories a person can fall under in terms of BMI.
- Underweight = < 18.5
- Healthy weight = 18.5–24.9

For example, a man who is 70 inches tall and weighs 165 pounds has a BMI of 23.7, which indicates that he is in the healthy weight range.
