> BTW. a month's worth of food takes less space than a month's worth of TP. I have questions... that I guess I don't really want to ask.

One answer is that what comes out is a lot less calorically dense than what goes in. This isn't arbitrary--it's practically a fundamental principle of metabolism/physics. Less isn't zero, though, and lots of life forms live on the output of others. Dung beetles, for example.

To answer the obvious question: it's true if you buy food with sensible caloric and macronutrient density. For instance, in a space of less than one roll of TP, canned meats can supply you with a day's worth of calories - and they're just halfway on the kcal/kg scale (mayonnaise is almost three times denser). If you want a more balanced diet, store flours, pastas, canned fruits&vegs, etc. and then make meals off them. I once did an inventory of the durable food supplies we had around the house, itemizing each product category to account for energy and macronutrients, and then boxed them all up for storage. In the end, I was surprised just how little space a month's worth supply for two takes, even allowing for a balanced diet. I recommend the exercise - especially now, as you'd probably like to know whether your buffer will last as long as you think, and whether it's balanced.

It's not the volumetrically small amount of food you're using that strikes me as curious, it's the spectacularly large amount of toilet paper. Holy shit!

  Don't forget dried beans and other grains. Calorie & carb dense, and also a shelf-stable source of protein.

  > For instance, in a space of less than one roll of TP, canned meats can supply you with a day's worth of calories - and they're just halfway on the kcal/kg scale Right, so, let's say 2 cans, one roll; two days, one roll. One month, 15 rolls? No. "Halfway on the scale"?" One month, 7 rolls? Maybe more likely, but I'm rounding up at every stage here, and granting you're eating only mayo. The math just doesn't come close.
