eh, each woman is different but my mum says her healthiest pregnancy was her first, when she was constantly travelling with my dad and had to deal with a huge move right in the middle. she didn't stop moving around and walking and as a result she had a lot less bloating and swelling and she gained less weight than with her subsequent pregnancies. strangely enough she was also less tired than with the other pregnancies where she 'took it easy' and rested a lot...
i don't think it's any different than when you're not pregnant. i feel more lethargic and i eat more for no reason when i'm doing nothing, but when i'm busy and keep active, i feel better and only eat what's necessary.
to each her own but i for one think it's better to keep active than act like pregnancy is a 9-month illness or an excuse to pig out on whatever you want.
