Quoting Δ ☮ ∂:" It depends. Some people have health problems triggered by pregnancy and can't lose the weight for years. Not everyone's body is the same. "
This is very true. Between pregnancy, my thyroid getting screwed up (the doc suspects pregnancy was a factor in that), and a car accident during pregnancy that screwed up my back, the cards were kind of stacked against me. I'm still about 60 pounds less than I was at delivery, though, because I was swollen with roughly 40-50 pounds of water weight at delivery.
