When you're used to eating 4000+ calories a day, your body gets used to consuming an amount of salt that is far beyond healthy and you develop a sort of tolerance to it.   When fats cook, they oversalt it to compensate for their tolerance to salt.  Fats also inhale food to consume calories as quickly as possible without taking the time to actually enjoy what they are eating, so they can barely even taste how salty the food is anyway.
