BMI calculator and readiness survey

To determine whether the OPTIFAST Program is right for you, health professionals start by calculating a patient’s Body Mass Index, or BMI. It is an estimate of weight-related health risks, based on your height and weight. The lower your BMI, the lower your risk.

The OPTIFAST Program is designed to treat people with a BMI of 25 or higher.
