Body mass index is one of the first things a provider looks at for medical weight management. It's private: your numbers stay on your device and are never saved or shared.
Body mass index (BMI) is a simple measure that compares your weight to your height. Providers use it as a first screening step for weight-related health risks and to help decide which care options may be appropriate.
| BMI | Category |
|---|---|
| Below 18.5 | Underweight |
| 18.5 to 24.9 | Healthy weight |
| 25 to 29.9 | Overweight |
| 30 and above | Obesity |
BMI equals your weight in pounds, multiplied by 703, divided by your height in inches squared. For example, a person who is 5 feet 6 inches (66 inches) and weighs 180 pounds has a BMI of about 29.
Prescription weight management programs are generally considered for adults with a BMI of 30 or higher, or 27 or higher with a weight-related health condition such as high blood pressure or type 2 diabetes. A licensed provider always reviews your full health history and makes the final decision.
BMI is a screening tool, not a diagnosis. It doesn't measure body fat directly and doesn't account for muscle mass, age, sex or ethnicity. Athletes, older adults and pregnant people may get results that don't reflect their actual health.
No. The calculator runs entirely on your device. Your height, weight and result are never saved or sent anywhere.
It's a useful starting point for most adults, but it has limits. A provider looks at BMI together with your health history, labs and goals.
If your BMI is 27 or higher, a licensed provider can review whether medical weight management may be right for you. If it's in the healthy range, our wellness and longevity programs can help you keep feeling your best.
Ranges based on CDC and NIH adult BMI categories. This page is for general information and isn't medical advice.
