Yikes, no wonder folks here only talk in 'base' weights.
Since this is backpacking light, attention must be paid to how much the food weighs. What point is there to pruning down the weight of the gear, often at great expense, if a ton of munchies are carried.
Not that I'd begrudge younger folk their munchies. There is another way, however.
It involves three meals a day, and even when much younger, there was no problem with energy levels while backpacking 6-10 hours a day, and that was before the pack weight was cut in half. All packaging is done using a U-Line packaging tool, looks like a giant stapler, that seals polyethylene envelopes and cuts off any excess, to create the lightest possible package.
For breakfast, a mix of instant breakfast, powdered milk and instant coffee is packaged in an envelope, and dissolved before use in cold water, and warmed if desired. A strip of 'fruit leather' is also consumed. That and a drink mix like cocoa or Alpine spiced cider are enough to provide energy and not feel hungry all day.
For lunch, just one energy food of choice. Tiger's Milk bars are small and light, nutritious, and provide me more energy than the bulkier hyped products. No need to repackage the bars, as no weight would be saved.
For dinner, a starch (rice, potato, pasta) is mixed with freeze dried meat, usually turkey or chicken, and seasoning, and packaged in the same size U-Line envelope as breakfast. Except the seasoning and thickening powders are packaged in a much smaller U-line sealed envelope that is sealed inside the larger envelope. This way, the starch and meat can be simmered till soft, and the seasoning with thickeners and sometimes veggies, can be thrown in later so less time simmering is needed - saves fuel and assures the food is fully rehydrated. The mix is designed to take always the same amount of water, the amount chosen depending on how much food it takes to fill the individual tummy and provide enough energy for the next day.
No longer use the sugary drink mixes. The berryish odors attrack wildlife. But another envelope of hot Alpine cider is nice with dinner.
All of the used envelopes and wrappers for a week fit into a ZipLock one pint freezer bag with room to spare, and weigh almost nothing kept inside the food bag.
With this system, food for a day, including packaging, is well under a pound, and I can go for a month like this, but stop occasionally to enjoy a good home-cooked meal.
A cut down Ursack, resewn with Kevlar thread, is used to hold a light zip-open food bag, and is hung at night. Not recommended for going to Grizz country, but while I don't go there anymore, I may add an odor barrier sack next year for black bears if tests next spring are positive.
Since the dinners are prepared from separately purchased ingredients, they are much more tasty than any prepackaged ones ever tried.
With the lighter food weight, a lighter TOTAL pack weight can be achieved, with more, not less energy and nutrition than derived from the meals bought prepackaged at retailers.
The larger supermarkets have plenty to experiment with, but organic ingredients are available at specialty stores if preferred. The freeze dried meat is mail-ordered.
