I haven't weighed myself since I was pregnant - don't see any point as it's not just about me putting on fat, it's about all the other baby-related gubbins that is growing too! This is a useful way to understand what baby-weight comprises (from Babycentre):
? At birth, your baby will weigh approximately 3,300g (7.3lb).
? During pregnancy, the muscle layer of your womb (uterus) grows dramatically and weighs an extra 900g (2lb).
? The placenta (afterbirth), which keeps your baby nourished, weighs 600g (1.3lb).
? Your breasts weigh an extra 400g (0.9lb).
? Your blood volume increases and weighs an extra 1,200g (2.6lb)
? You have extra fluid in your body, and amniotic fluid around the baby, weighing 2,600g (5.7lb).
? Plus, you will lay down some fat during your pregnancy to provide you with extra energy for breastfeeding. This comes to about 2,500g (5.5lb).
So, by the end of pregnancy you will weigh about 11,000g (24.2lb) more than you did before you became pregnant.
This is all average weight gain though, and no one is average! Also worth remembering that if you breast feed afterwards, you actually need about an additional 750 cals a day to meet your baby's requirements, so prob not the time for drastic dieting (rather, up the exercise).
