There are going to be a lot of techniques to lower your overall weight.
The simplest being to simply buy lighter, more expensive gear.
A simple way that I dropped weight was to drastically compress as much air out of my gear as possible. It's amazing the amount of air people carry around in their packs, necessitating large backpacks with heavy suspension systems.
Get OR compression sacks and get creative. Stuff, don't roll, everything. I can get my Winter sleeping bag into a 8L compression sack and then the tent, my clothes and a puffy goes in another 8L compression sack.
From trying different compression methods I got my pack size down to 30L for overnight trips in the Winter. My 30L pack weighs less than a pound. Note that I'm also bring a camera tripod, 4 lenses, batteries... etc, as well as a stove, sleeping pad and sometimes helmet, crampons and ice axe. I share food weight with my wife.
