As your blood sugar goes down, your judgment deteriorates as well. This is much more important than people getting cranky, since mistakes in judgment can lead to serious, or even fatal, errors.

Always keep something in your pack that is nutritious— but not too delicious. That way, you won't eat it unless it's absolutely necessary, and you won't accidentally deplete your emergency food supply.

Even tho I use and realize the importance of the 'mainstays' in our hiking diets, and I've been at it for forty plus years, I still don't mind carrying something extra or special and I really don't mind if it is fresh fruit, a sub sandwich, chicken leg, baked potato, maple syrup or anything else that is available when I'm packing.
The weight has never prevented me from hiking. The taste I love. And the looks when I pull out something different or refreshing is worth much.
Especially if I can share it.
I also still like stopping along the way and either useing a twig stove or small fuel stove having a cup of tea.
It quenches thirst in the summer and does that and provides warmth in the winter.

Hi TSAR, I have been known to take a frozen rib eye and potato for my first meal at camp. It's enjoyable and nutritious. One of my buddies is from England and has us all taking noon tea, it's a good way for us to take a minute and discuss the rest of the day.
