The American College of Obstetricians and Gynecologists has come out with recommendations for weight gain during pregnancy based on the mother’s body mass index and on updated tables from the Institute of Medicine. For overweight women with a BMI of 25–29.9, ACOG recommends a total weight gain of 15–25 pounds. For obese women (BMI 30 or higher), the guideline is 11–20 pounds. ACOG does not differentiate between grade I, grade II and grade III obesity (BMI of 30–34.9; 35–39.9; and 40 or higher, respectively). The weight gain recommendations are predicated on determining a woman’s BMI at the initial prenatal visit.

ACOG also emphasizes the need to individualize weight plans based on the health of both the mother and the growing fetus, especially in cases where the mother could be advised (or wants) to lose weight during her pregnancy.
