Question: what food gives you the most energy?

If you had a gram of carbohydrate, a gram of protein and a gram of fat you’d get most energy from the fat. So the food that gives you the most energy would be one that was just fat. Something like lard. Not that many people eat lumps of lard and its not something I’d recommend!…

Interestingly though, i’m working with some people who’re crossing Antarctica. They have to carry all their food with them on sledges, so it needs to be lightweight. But they’re going to be using up to 10 000 calories a day, which is four times what the average man needs in a day. So to make sure they get enough calories and to keep the food lightweight they’ll end up eating sticks of butter for their breakfast. Sounds grim, but it’ll keep them alive!
