I knew a few hikers who went completely “stoveless” last year, and one thing I noticed - their food was heavy, but not necessarily rich in calories. Bagels, tuna, pita bread, etc… Sounds good, but a 300 calorie bagel doesn’t get you very close to the 4-6K calories needed per day to hike.
Without careful planning, you might end up carrying fewer calories for the same weight in food, due to the extra water contained in ready-to-eat products. For short hikes, you can get away with that, but you end up needing every calorie you can carry on a thruhike.
That said, it is really nice to have a few meals that don’t need cooking - lunches, snacks…
