I've done some body-weight stuff (sit-ups, push-ups, squats), but I can't really get a good aerobic exercise inside the house.

I have a pretty good grasp on what I'm cooking anyway. I have my own spreadsheet where I extracted the Nutritional Information label (or looked up bulk foods on fat secret website), to plan to keep my calories until 14000/wk and keep my sodium down. For me, it was easiest to go vegan: beans, quinoa, greens, nooch, plant milk. I have been eating out more, and that's no on there, nor do they publish nutritional information (local family chain). But, I also get the "vegetarian" faire there (there's a white sauce so I'm pretty sure there's dairy in it) but I know I can skip a couple of my meals to roughly balance that, caloricly at least. That got me down the first hundred. I still need to lose more, but it's harder now; I used to be closer to a gym... among other things.
