The point of MREs is that they're ready to eat, ie. no cooking whatsoever, and they have a long shelf life. Neither of these things are pertinent in planned non-combat scenarios. For unplanned excursions or while evading enemy combatants, your best bet is actual MREs or civilian knock-offs.
Otherwise, for camping, for the first night, I pack frozen steak and veggies wrapped in aluminum foil and vacuum sealed. Heavy, but it only gets carried for the first day, and it's great to just throw dinner on hot coals and not have to do anything. After that is Knorr meals with added freeze-dried chicken for extra protein while actively hiking, or if I'm ending up someplace with fish I only carry rice for those days. All of my breakfasts are just oatmeal and coffee, lunches are cheese sticks and quartered lengthwise summer sausage wrapped in tortillas for the first four days, knorrs after, snacks are just gorp or Cliff bars.
>>2078328>Assuming ultra min-maxing, how many calories/days worth of food should you be able to get per liter?I keep my rice in 2L soda bottles, I just weighed them (tared at empty) at 3.134lbs at 4 cal/g, so 5686cal/bottle or 2843cal/litre. Should be close to the same for sugar, flour, lentils, pasta flour, and about half that for oatmeal because it packs much looser. Fats get you 9cal/g, but you need something to soak it up with or most of it'll go right through you without actually being digested. Peanut butter is 6.4 cal/g with no dead airspace and pemmican is 6.6 cal/g with no dead airspace, but I don't know how either translate to volume. I checked a jar of peanut butter and it's packed by weight, not volume, and I'm not filling a bottle with it, sorry.
