Food packaging carries the energy content both per 100 g and per serving. The manufacturer's idea of a serving is likely to be less than yours. On the other hand, the food for three days does mount up, so some prior experimentation to discover just how much of each foodstuff you actually need to take is a good idea.
Consider how much cooking time (and therefore fuel) your menus will require (remember that quite a lot of hot-water cooking can take place with the pan set to one side while you use the burner for something else).
Consider the difficulty/ease of washing up after your cooking.
Consider the amount of rubbish generated. It might be worth re-packing some of the stuff.
Consider the likely effect of intense day-time heat on perishable foods.
Bear in mind that dehydrated food weighs a good deal less than ordinary food.
|During an expedition
you need about 10,000 kJ per day. You can leave protein intake for
non-expedition days. Carbohydrate gives quick-release energy, and so is
good through the day. Fat gives slow release energy, and so is good as
part of your evening meal.

might aim for.
|Sweets and snacks will
give you plenty of energy during the walking part of the day, so long as
you have enough of them.
