THURSDAY, Aug. 29, 2024 (HealthDay News) -- Breastfeeding helps women shed those extra pounds of "pregnancy weight," a new study finds, and the effect is even more pronounced for moms who were overweight before their pregnancy. Among women who exclusively breastfed their baby during its first year, women who were normal weight prior to pregnancy lost weight, but still retained about three extra pounds of their pregnancy weight, reported a team of researchers in Singapore.
However, breastfeeding new moms who were already obese or overweight before their pregnancy lost all their added pregnancy weight, plus an average of another half-pound on top of that, the same team found. Women who chose not to breastfeed or had a mix of formula plus breastfeeding retained much more pregnancy weight, with average weight gains at 12 months post-delivery of about 6 and 8 pounds, respectively. "In this year-long study, we made an interesting discovery -- an additional benefit [of breastfeeding] for women with high BMI," said study lead author Dr.

"Due to hormonal factors, there is a re-distribution and management of their body fat to the extent that there is an opportunity for them to lose more than the postnatal weight gain," Ling explained in a hospital news release. Her team published its findings recently in the journal Nutrients .
The new study tracked the weight of 379 first-.
