Why can people last longer without food than they can without water? Food has water in it. Does this not factor in to survival?

I’m not a scientist or whatsoever, so if I said something wrong, feel free to correct me politely.
We exhale like one litre a day of water just by breathing, so we need to “get back” that amount, plus all the liquids we lose when we sweat and urinate. Anyway, we can live longer without eating because our bodies can slow down their metabolism a little, so that they use a little less energy and can go on longer. Plus, the human body stores the unused energy as fat, that will eventually be used when needed
Anyway yes, food contains water, and obviously the amount of water contained is different for every food, that means that we actually take water even by eating certain foods.
