* Insane portion sizes when I eat out.

* If there is a smaller size it feels not worth it (it's not that much smaller, but the cost is still dis-proportionately high, adding a psychological barrier to ordering less)

* I hate leftovers, but I was also given that 'starving children in Africa' speech as a kid... I hate leaving food behind.

* I have a 'desk job' and thus don't get enough exercise.

* American culture is predominantly a car culture, our cities, suburbs, and rural areas are built to that standard.

* I wasn't, really, at all trained in making HEALTHY food as a kid.

* Making healthy food takes some time, or at least a good bit of planning.

* Making food for one means I can't keep the best healthy ingredients around. (Fruits, vegetables, to a degree bread) Even the smaller store sizes are at high risk of going bad before I get them, and they have a cost high enough to make me lust for prepared foods.

* Most of the prepared foods are made to sell on taste, and thus have a lot of what isn't 'healthy' for us.

* We've also, apparently, been on a war against fats, when their common substitute sugar is actually a more insidious enemy.
