This is a tough one for me. Most of the items listed here are basically junk food, along with some dried fruit & PB&J. I am trying to change what I eat because I developed an addiction to chocolate, sugar, fat and salt so that when I have a bite, I'm like an alcoholic with his first drink - off to the races, throwing down everything I can find. When I was young, it made no difference in weight but once I started a desk job in my 30s I gained 1-2 pounds/year. Now, I'm working hard to lose it this year. So far, I'm down 15 pounds, thanks to a no-tolerance policy on the stuff above and 5 days a week at the gym. I've got another 25 to go before fall and I'm feeling stronger and more energetic.
So, I think my no-tolerance policy on sweets and the salty or fatty stuff is going to be in place from now on, which knocks out nearly all of what you guys take along for snacks.
Don't laugh, but a friend of mine who changed his diet and looks great swears by snacking on kale. Kale has the highest nutritional value of any food and is light and cheap. Plus, I found that once I quit eating fats and sugars my taste buds changed completely to where the natural taste of things really comes alive and things I didn't use to like, I do now. And, anything with much fat tastes disgustingly greasy and sugary stuff tastes way more sugary than it used to. I may try his kale idea on some short hikes, maybe also take some dried fruit, though despite the name it tends to be heavy to carry.
