next trip, I'll pre-calculate the calories I'll burn and only bring that much food

I assemble and prepackage each meal I intend to eat on a solo backpack. Even though I try to inject some variety from one day top the next, it always ends up very close to 28 oz per day and somewhere between 3000 and 3100 calories. The longer the trip, the less likely I have any food left over at the end, unless I purposely brought a small emergency ration I never intended to eat.
