When you lose a baby do you still stay fat?

It takes approximately 6-8 weeks to return to pre-baby weight. This is because of the increased amount of fluid in the mother's system that must be reabsorbed into her body and her uterus must shrink back to its normal size. Breastfeeding releases oxytocin, a hormone that helps the uterus shrink, so breastfeeding will help the mother "lose baby weight" faster than women who do not breastfeed.
