It was an interesting exercise taking nearly one week’s food on my recent trip. To recap, I took six breakfasts and six evening meals and enough for seven lunches. The total weight including packaging and packing cells/food bag was 5.4kg. I reckon I could cut around 600g from that total and still be OK.
I finished with quite a lot of nuts left over. I carried 620g of Brazils/macademias/almonds plus a 200g packet of salted peanuts and cashews (which I finished) . I think 350g (50g per day) of Brazils/macademias would have been enough (I’d leave out the almonds too). I had some surplus dried fuit, around 150g. The Biltong was great to mix in with breakfast and some evening meals but I could’ve done without it saving 200g or so. Six packets of Biltong was surprisingly bulky as well. Most of the rest of the food I ate completely.
As a rule of thumb, I think 700-800g is reasonable per day. You could probably get away with a bit less if you were resupplying every 3-4 days and eating in civilization. However, for a wilderness trip of a week, I think the minimum per day you could get away with is about 750g per day. Indeed, if you were going somewhere obscure, you’d probably want to take a bit extra to cater for potential delays.
I really liked having the Summit to Eat Scrambled Eggs with Cheese for breakfast, despite taking a bit longer to prepare and some extra fuel to heat the water. This in combination with a granola bar (and some tea) was quite a satisfying breakfast. For evening meals, I’m happy with a freeze-dried main meal and some dried fruit for dessert (dried dates for four meals and dried mandarins for two).
At lunch time, I didn’t particularly miss sandwich type lunches and a combination of Tracker bars, Tunnock’s caramel wafers, Nakd fruit fars, sesame seed bars, nuts (Brazils, macademias, almonds, cashews, peanuts) and dried fruit (banana chips plus berry mix) kept me going both for lunch and for snacks.
I didn’t tot up calories but I’d be really surprised if my daily intake was enough to compensate for my energy consumption. I had definitely lost weight by the end of the trip, although how much I don’t know as we don’t having any scales at home.
