my no cook food is usually never less than 140cal/oz.

This is interesting. 140 calories per oz. is the equivalent 4.9 calories per gram. That's pretty high. Both pure carbohydrate and pure protein are 4 calories per gram, and of course water, salt and fiber have zero calories per gram. It would be impossible to find edible no-cook food that doesn't have some water content and only the most refined foods would have no fiber. So, it seems to me your no-cook foods must be very heavy in fat.

It's not as if that is inherently bad on a short backpack trip where you're getting plenty of exercise, but I personally would find getting a very large percentage of my calories from pure fat would be unappetizing. I couldn't eat potato chips (or their equivalent) for breakfast, lunch and dinner.
