Interesting topic -
My normal trip length probably lasts 10 - 12 days, (can often go longer as I regularly lose time easily in the Sierra), and as such am used to experiencing varying degrees of hunger as to what day it is in the trip agenda...Nowadays, even plan on this hunger phenomena/ pack accordingly.
Talking only dinners now - First few days in, usually cannot eat that much and am usually bushed by nightfall, and this is when the easiest meals carried are consumed, (if I eat dinner at all). Boil & bag dinners (usually the only ones eaten all trip) are the rule the first 2 or 3 days...maybe even the singles.
Somewhere about day 4, hunger really starts creeping in just about the time my legs show up...coincidence?
Much more food is needed but do not mind spending the time to actually cook up something...FYI, usually by now trout are on the menu and as such, all that is needed to prepare are just some high caloric "sides". (BTW, the grits thread sounds yummy.) Those supermarket noodle/rice dishes in a pouch work seem to out well/taste fine with a little Asiago, garlic, and herbs...just add trout.
These days, it is not uncommon to only take 10 dinners along on a 12-day-trip. Still I never eat everything...(do sponge off/barter with others too, so that helps). Somehow it always works out.
