How the Pregnancy Weight Gain Calculator Is Calculated

Recommended total pregnancy weight gain is based on Institute of Medicine (IOM) guidelines, which set a target range according to your pre-pregnancy BMI category — lower BMI categories are given a higher recommended gain, higher BMI categories a lower one — then divides that total evenly across a 40-week pregnancy to show your recommended gain to date.
