my typical backpacking day begins w/ a cold (sometimes hot) cereal w/ powdered WHOLE milk- hard to find but has a lot more calories than skimmed powdered milk, a couple of breakfast bars to go w/ my morning coffee (the new Starbucks instant isn't like instant

). there is no "cooking", only water boiled for coffee (or for hot cereal)
snacks (mid morning/mid afternoon)- two cliff bars- of late I'm favoring their Mojo bars- these are eaten on the go
powdered gatorade - two packets- adds a few calories, but more importantly lost electrolytes/salt- these are drank on the go
stop for a midday lunch- mini pita pockets (this was a great find!) w/ hard salami and a "hard" cheese (sharper cheddar/jack/etc)- even in hot weather, w/ a little careful packing, I've found the cheese and salami to last a week w/o any problems
supper- boil in the bag meal (usually purchased freeze dried, but occasionally something I whip up)- again no "cooking"- simply boiling water
I've totaled my typical trail caloric intake and it's roughly 2300-2500, I've estimated my caloric expenditure and it's probably in the 5000 + range- backpacking is a great way to lose weight
my food/beverage weight is roughly 20 oz/day and everything is relatively low volume, it's all kept in one bag (but packaged individually) that doubles as my bear hang bag- the bear rope/s-biner stays in the same bag
here's a pic from a recent trip- food for two for six days/five nights
