My opinion will only be one of thousands but I found the key points to reducing the weight of your food ultimately depends on these:
#1 - Reduce packaging
#2 - Use dehydrated when possible
#3 - What is dehydrated, should be high calorie content
I don't think there is a one size fits all food list for anyone. However, you may find the following Excel spreadsheet helpful... http://www.backpackinglight.com/backpackinglight/images/bpl-gear-list-spreadsheet-contest-meir-gottleib.xls
It was the 2005 BPL winner in a contest for planning spreadsheets. It is loaded with fun information including menus and help planning them.
Having said that, I'll be the first to admit I use to eat terribly on the trail. I'm a type 2 diabetic and last summer I kept hitting the wall badly on long days. It was all due to eating poorly. My solution was to purchase a dehydrator and start experimenting. I personally enjoy the Freezerbag Style of cooking and you can find some helpful info on getting started at www.freezerbagcooking.com -- No, I don't own the cookbook she sells there.
It should be noted though that a great deal of your favorite home recipes can be dehydrated into great trail meals.
As an example if on a multiday hike, I usually have oatmeal in the morning with either Clif bar or a Snickers, snack on trail mix, have light noodles like Ramen which are high calorie for a lunch, an afternoon snack of a Clif bar or Snickers and then top it off with one of my own meals for dinner such as Chili Mac, Burritos (easy to do on trail) or Spaghetti with garlic toast. Usually my evening meal has a good mixture of fat, protein and calories.
If I am doing a less strenuous day, then I adjust my calorie intake down.
The last thing I find helpful on reducing weight is carefully planning what it is I will eat each day and take only that food. In the past I always came home with extra food and that translates to extra useless weight.
Hope some small amount of this info helped you.
