I consider myself grateful in that carrying a bear canister as a necessary legal requirement made me more aware of not only opting for dense/compact food choices but also made me better at reducing packaging and opting for food choices NOT heavily packaged, learning about higher overall
nutrient dense higher caloric content per ounce choices, gave me a better idea of my daily caloric needs, made me a better food planner by being more able to ration my caloric needs out over a longer period based on physical and mental needs not emotional desires, helped me gain better control of my appetite, led to beating food addictions, made me learn other techniques for maintaining a feeling of satiation, and, overall, made me a better even lighter wt kit backpacker.
