Women with gestational weight gain ≤9 kg, (recommended by the Institute of Medicine), retained less postpartum weight compared with those who exceeded 9 kg (median −0.7 vs. 1.5, <italic>p</italic> < 0.001). Ninety‐two percent in both weight gain groups initiated breastfeeding.

Women who adhered to gestational weight gain recommendations had significantly lower postpartum weight retention. Breastfeeding for 6 months was negatively associated with postpartum weight retention.</p> </sec> </abstract>
