You do though, that's what I'm saying. "Electrolytes" is potassium, calcium, magnesium, sodium, chloride. You'd struggle to find foods that don't give you at least one of those. It's like asking "How do you refill your calories if you do workouts?". By eating. Eating does it. Electrolytes as a concept outside of chemistry and science are just a marketing ploy to make you buy gatorade and supplements, nobody needs to try to get any more than they already get through diet unless they are on an extreme workout regimen, like immediately during and after a marathon.
