The last picture is exactly that: she's lying on the floor, expanding no energy whatsoever. That posture is actually one some people have used throughout time to sleep in cold weather (fewer points of contact with the cold ground, body folded together to conserve heat). It's even lazier than me sitting down on a chair and calling it an air squat. (edit) Managed to find the article I was thinking of when I mentioned that sleeping position. Not exactly the position she's in, but close enough. With that much fat, she could probably sleep naked in cold wind and not suffer from exposure.
