Basically, chloride and phosphate deplete sodium from the body. Table salt cannot restore the sodium levels permanenly, as the chloride excretion depletes as much sodium as the salt provides. This causes cravings and people keep eating, the salty food provides temporal relief and the body associates sodium cravings with actual hunger. I think the food industry know it, that's why they switched to phosphoric acid, they make people overeat on purpose.

Mix some baking soda with citric acid in a cup of water and drink it, you stop being hungry all the time.

And East Asians "salt" with sodium glutamate, which is why they are not fat. And perhaps even the reason why MSG is perceived as making people sick, because when you eat a lot of it and you are overweight, it makes you feel bloated and fat.
