check out the pregnancy and parenting section, and then the thread: are you pregnant and needing help with your goals?

There is alot of talk in there about essentially losing weight while pregnant (by not gaining, or by gowing down a little) it's a great discussion, and headed by a pregnant baby nurse too!

There are a lot of us who are losing, or trying to lose while preg. it doesn't seem to be an issue, esp if you're very overweight AND eating properly. Ie: whether you're in a slight caloric deficit or not you need enough protein for example, and good foods. It wouldn't be good for your baby to live off soy protein and frankenfoods/artificial sweetners.
