How the GLP-1 eligibility calculator works
It works out your BMI, checks it against the usual GLP-1 thresholds, then reads your health answers from top to bottom.

1. Your BMI
Body mass index (BMI) compares your weight with your height. The calculator uses the standard formula and shows the result to one decimal.
US unitsBMI = 703 × weight (lb) ÷ height (in)²
MetricBMI = weight (kg) ÷ height (m)²
Example703 × 172 ÷ 65² = 703 × 172 ÷ 4,225 = 28.6
The example is a 5 ft 5 in woman who weighs 172 lb and has high blood pressure.
2. Your BMI category
Under 18.5 is underweight, 18.5 to 24.9 is healthy, 25 to 29.9 is overweight, and 30 or more is obesity, in three classes (30 to 34.9, 35 to 39.9, and 40 or more). At 28.6, the example woman is overweight.
3. Your answers, in order
Under 18, or a safety answer such as pregnancy, stops the check. A BMI of 27 or more, 25 or more with a weight-related condition, or 22 or more if you take a GLP-1 now, points to a full-dose plan. With high blood pressure, the example woman is in that range. Any other BMI from 20 to 26.9 points to a low-dose plan, often called microdosing. Pancreatitis or a condition under More sends the result to a clinician first.
BMI can misread very muscular people and older adults, so the clinician looks at your full health picture, not only this number.
GLP-1 BMI criteria and qualifying conditions
The usual criteria for GLP-1 weight loss treatment are adults with a BMI of 30 or more, or 27 or more with at least one weight-related condition. They come from the FDA labels for semaglutide (sold under the brand name Wegovy, with the same active ingredient as Ozempic) and tirzepatide (sold as Zepbound, the same active ingredient as Mounjaro).
Olive prescribes compounded semaglutide and tirzepatide, not branded medications. Olive's clinicians start from the same thresholds, and they may also consider a full dose from a BMI of 25 with a weight-related condition, or a lower dose from a BMI of 20.
If you are very muscular, your BMI can read high while your body fat is low. Our body fat calculator gives a second view.
| Condition | Counts toward BMI 27? |
|---|---|
| High blood pressureExample | Yes |
| Type 2 diabetes | Yes |
| Prediabetes | Yes |
| High cholesterol | Yes |
| Obstructive sleep apnea | Yes |
| Heart disease | Yes |
Who shouldn't take a GLP-1
Some answers rule GLP-1 treatment out for now. Others don't rule you out, but a clinician needs to look at them first. That is why the calculator asks.
