The short answer: a BMI of 30+ qualifies you outright. A BMI of 27 to 29.9 qualifies you if you have at least one weight-related health condition. But the real story is more nuanced — and in 2026, the eligibility landscape is shifting.
The Official BMI Thresholds
| BMI Range | Category | GLP-1 Eligibility |
|---|---|---|
| 30.0+ | Obesity | Qualifies without comorbidities |
| 27.0–29.9 | Overweight | Qualifies with one weight-related condition |
| 25.0–26.9 | Overweight | Case-by-case, emerging clinical support |
| Below 25 | Normal weight | Generally does not qualify |
Why BMI Is Not the Whole Picture
BMI is a screening tool, not a diagnosis. It does not account for muscle mass, body composition, or where you carry weight. A person with a BMI of 28 and significant visceral fat, insulin resistance, and elevated blood pressure may be at higher metabolic risk than someone with a BMI of 31 who is metabolically healthy.
This is why prescribers increasingly look at the full metabolic profile rather than a single number. Waist circumference, fasting glucose, A1C, lipid panels, and blood pressure all factor into the clinical decision.
2026 Update
The American Medical Association has recommended that BMI be used alongside other measures of metabolic health, not as a standalone criterion. Some telehealth platforms have already adopted this broader approach.
Calculating Your BMI
BMI = weight in kilograms divided by height in meters squared. In imperial units: (weight in pounds × 703) ÷ (height in inches²).
For example, a person who is 5'8" (68 inches) and weighs 200 pounds has a BMI of approximately 30.4 — which meets the obesity threshold.
What If Your BMI Is Below 27?
Patients with a BMI between 25 and 27 generally do not meet standard GLP-1 prescribing criteria. However, there are emerging cases where prescribers consider GLP-1 therapy for patients in this range who have significant metabolic dysfunction — particularly those with pre-diabetes, PCOS with insulin resistance, or non-alcoholic fatty liver disease.
If you fall into this range, a conversation with a qualified prescriber about your complete health picture is the right starting point.

The Bottom Line
BMI thresholds are guidelines, not hard cutoffs. The prescriber evaluates your entire health profile. If you are close to qualifying, gather recent lab work (A1C, lipid panel, fasting glucose) and be prepared to discuss your full medical history during your consultation.
