Weight and ease of preparation
Keeping the weight down is an important consideration. For persons of average build, a nutritious, well-balanced outdoor activity diet for trips up to about two weeks can be made up of foods which weigh about 900 g per person per day. When tired at the end of a hard day, ease of preparation can often make the difference between eating the planned meal, having a quick snack that may not be especially nutritious or energy giving, or having nothing at all. On extended trips, it is particularly important to have meals that are quick to prepare and need little washing up afterwards.
