I'm thinking this is a bit low. First of all, a gallon of food is a huge amount of food. I'd have serious trouble eating that in a whole day, so I could get two days walking out of it for sure. But maybe they're including water as part of the gallon, in which case there's not that much food at all, since I could go through a gallon of water in a few hours of exercise. But it seems wrong to count water as fuel. It's more analogous to your oil and coolant than your gasoline.
