Every trip I come home with extra food because I pack for the hunger I imagine rather than the hunger I actually have, and all that extra is just weight I carried for nothing. At the same time I am scared of running short on a hard day. For people who have dialed this in, how do you estimate what you will actually eat per day, and do you plan by calories, by meals, by weight, or just by experience at this point? Trying to stop hauling food back out every time.
