BMI calculator
Body Mass Index (BMI) is the most common screening tool used by clinicians when evaluating eligibility for weight-management programs and GLP-1 medications. This calculator shows your BMI category and flags whether you meet typical screening thresholds.

BMI is one screening tool. It doesn't measure muscle vs fat, and clinicians use additional criteria for GLP-1 eligibility.
BMI ≥ 27 is a common screening threshold for GLP-1 programs (with a comorbidity). Final eligibility is up to a clinician.
How BMI relates to GLP-1 eligibility
Wegovy, Zepbound, and Saxenda are FDA-approved for adults with BMI ≥30, or BMI ≥27 with at least one weight-related comorbidity such as hypertension, type 2 diabetes, dyslipidemia, or obstructive sleep apnea. BMI is one screening signal. Clinicians use additional criteria including waist circumference, metabolic markers, and medical history.
Limitations of BMI
BMI does not distinguish between muscle and fat mass, so it can misclassify athletes and people with high lean muscle as "overweight." It also doesn't reflect fat distribution (visceral vs subcutaneous), which matters more for metabolic risk than total weight. Treat BMI as a starting screen, not a diagnosis.
