Find out if you're eligible

Eligibility is determined by a licensed provider during your consultation — not by a calculator. Choosing a protocol starts the intake: secure card on file first, then the provider questionnaire.

What the number means

Reading your BMI

What BMI is

Weight in pounds, divided by height in inches squared, multiplied by 703 — the standard formula US health agencies use for adult screening. It sorts adults into four broad categories. Metric entries use the same measure — weight in kilograms divided by height in meters squared.

The standard categories

  • UnderweightBelow 18.5
  • Healthy weight18.5 – 24.9
  • Overweight25.0 – 29.9
  • Obesity30.0 and above

What it does not tell you

BMI does not measure body fat directly and cannot tell muscle from fat — athletic adults can score high without excess fat. It is a screening measure, not a diagnosis. A licensed provider reads it alongside your full health picture. The standard adult categories apply at ages 20 and up and are not used during pregnancy.
