Ok,I went to the pantry and looked at my hiking foods.I would like to know just what one can eat to get 4000 calories?I note that a slice of Spam is 250 calories while the 6.4 oz bags of Starkist Chunk light tuna in Water are 180 calories for the whole bag.But the same bag packed in sunflower oil is 330 calories.Rice I had panned out as 150 calories for a 1/4 cup.I normally prepare it 3/4 cup at a time so that would be 450 calories.Ramen noodles are only 190 for a bag while a bag of Laura Lynn Deluxe Mashed potatoes would yield 400 calories for the 4oz bag.Meanwhile,that old standby known as Kraft Mac and Cheese indicated 750 calories for the 7.25 oz box but you will have to boil 6 cups of water to get the whole box done.So to put this in perspective,the little meal I fixed last week while playing with my gear and testing my back out in the woods was one bag of Spam at 250C. and 3/4 cup rice at 450 calories.That was only 700 calories and took not quite an oz of fuel and 1.5 cups water etc.I don't see how anyone can eat enough or carry enough to not starve to death out there....
Any pointers appreciated.I do know olive oil and pnut butter are fairly high but the pnut butter is pretty heavy.
