Just thinking as I put together a food plan for my next trip. I am always interested in the great variety of opinions and expertise from you all....
I know some folks go big picture and basically gather a variety of their favorite foods adding up to what their experience and metabolism says is the right weight (mine is around 1.5 lbs of food per day for the average miles I do). Others detail each item and come up with a calorie count per day that meets their goal based on the same experience (mine is around 2,800 - 3,000 per day for a short trip with average climbs - adjusted higher for more elevation gain or longer miles).
I tend to balance both methods but make sure I have a variety of foods to keep things interesting. I do much less planning for a weekend trip (often just throw a lot of stuff in from the kitchen) than I do for a 5-7 day trip.
Which do you lean toward, or are there other options that I don't practice?
