I'll start with the caveat that I follow a high fat, low carbohydrate approach to nutrition, avoid grains in my diet, and am not averse to salt. YMMV.

I've made my own dehydrated food before but usually time constraints prevent this so I usually rely on various pre-made meals that I've listed below. Also, I rely heavily on egg based freeze dried meals since most of them (not all) tend to not have any added grains and are the best bang for the buck on a caloric basis in my experience.

In the back country I usually run a combination of an instant Keto/Bulletproof coffee, freeze dried meals, dried or smoked meats and pemmican, plantain chips and some nuts and dried fruits(very limited amounts), and a protein supplement to have with dinner. I also have experimented with taking butter, ghee, tallow, and butter of the gods in with me to add to freeze dried meals to up the fat content.
