someone was asking over in the /mlp/ preg thread how fat and chubbiness would affect ponies during pregnancy, here was my thoughts

>Aj would stay fit exercising daily even into the last few days persevering to do some form of exercise/work around the farm, maintaining a godly appetite throughout meaning while staying strong she'd end up with a bit more padding over all, but post birth she'd burn it off fast.
>Dash would be much the same except she wouldn't be working around the farm she'd be doing her flying, she'd generally resist cravings as much as possible and stay as slim and toned as possible so she can still train efficiently.
>Rarity would not be exercising to keep her weight down but i could see her moving onto health foods allowing her to relive cravings by eating loads of low calorie foods near constantly when not working, while maintaining her prim figure as if she puts on any ammount of weight she has a freakout, yet she'd relish the challenge of designing a maternity range.
>twilight would get hefty after the 11 months are up, indulging in more relaxing reading time while pregnant and with spike on hand to bring her food i could totally see her getting quite plump, only form of exersize is pacing while stressing that she'd done everything to be a good mother
>pinkie would eat an unholy amount of food particularly favoring anything sweet as normal, yet much to the envy of all the other mothers of ponyville hardly ever puts on a pound. Not skinny but not fat either just average amount of chub for a healthy pony.
>flutters would retain her willowy build though out most of her pregnancy, gaining a tiny bit of chub towards the last few months for reasons out of her hands as most of the animals in her care make a point to return the favour and take care of her 24/7 during the last trimester and with the large amounts of food they collect for her, she feels to polite to refuse it.

Any thoughts, agreements or disagreements?
