Body Mass Index (BMI) is calculated from your weight and height and provides a general indication if your weight falls within a healthy range. There are four BMI categories:

• Underweight: less than the 5th percentile
• Healthy weight: between the 5th and 85th percentiles
• At risk for overweight: Between the 85th and 95th percentiles
• Overweight: Higher than the 95th percentile

Too much body fat is a problem as it can lead to health problems. If your BMI indicates that you are over or under weight, you may want to contact your physician for advice.
