I didn't lose any weight but I believe cutting trans fats out of my diet helped me conceive a sticky bub. I was 41 at the time and supposedly only had a 5% chance of even getting pregnant at that age, yet had 3 pregnancies in the one year (no fertility drugs were used) and the last one was successful - around 6 months after cutting out trans fats. If you haven't given it a try I highly recommend you do.
