I was told it was ok to lose during the 1st trimester, & that I'd probably "bounce back" during the second trimester. I ended up dropping almost 20# in the first trimester (despite never really being sick...my metabolism LOVES early pregnancy apparently), and I'm currently 24+5 & still down over 5# from my pre-pregnancy weight. My doctor told me that it was ok, since my baseline pre-pregnancy is "overweight" that I can aim for a zero-gain pregnancy, but that I should be proud if I can keep it within 15# (which at this point is my max-gain goal).

BUT: My doctor said I shouldn't intentionally TRY to lose weight while pregnant, though. That's just kind of where I shook out when eating at maintenance with moderate exercise, mainly being walking (I had been on a weight-reduction program when I got pregnant).

I work in a community health clinic, and the midwife at our office has one patient right now who was so overweight during pregnancy, the medical recommendation IS for her to lose - but she is well over the 350 mark. Unless you are that high, I wouldn't think actively trying to lose weight would be recommended. I would say that you're doing a pretty great job managing your gain though.

I use that calculator to make sure that I'm on track. I went off the rails for a bit with lots of eating out, but after a week of stabilizing the water weight has come off and I'm back where I should be.

My doctor says to eat when I'm hungry, but mindfully. Make sure your diet is balanced and you're eating to comfortably satisfied and not stuffed, give in to cravings every now and again, keep moving, and remember to enjoy your pregnancy. She says that's the secret to weight management success in pregnancy.
