This is something we are working on trying to do house wide, not just her and not just me but both of us for the sake of our child (and future kids). I just do not see the reason why people get lazy about their health.
I think a lot of times the unhealthier food is faster and cheaper. One of the reasons I think most people go to fast food places. The wife and I are trying to eat healthier, but it does take some more time for us.
