No, stupid, you don't stuff your maw while pregnant. Leads to gestational diabetes, higher birth weight (over 9 lbs), delivery complications, & excessive weight gain is especially bad for tendons & ligaments in the mother. This can easily cause planter fasciatis & hip & knee issues.  If you're doing it correctly, half the recommended weight gain is baby, placenta, & fluids.  Being 255 at 5.4" is a dangerously high delivery weight. God forbid something goes wrong & an emergency delivery is needed. Minutes moving that nasty fupa around are minutes needed if the baby isn't getting oxygyn. In 2.5 months, you can drop the rest of a normal weight gain by breastfeeding. Nothing special needed.
