Sure I know all about nuts and seeds. I eat very low carb (usually) and have been freeze drying my own backpacking meals and they are great. Today I found a new "wheat belly compliant" snack that would probably work for 2-3 days on the trail depending on weather. It's an uncured "beef stick" by Greenridge Farm. No nasty additives and fillers. Completely cooked. Strong smell though so I wouldn't suggest carrying it in a place with lots of bear activity and you should definitely hang your food bag well. I may actually repackage individual sticks for my next trip as they come 4 in a package.
Found these at Costco.
