The human body is not a steam engine, it reacts to all stimuli. You don't need to constantly measure electrolytes or keep track of every single micronutrient you consume. Hunger is a physiologic response to a lack of food, and seeking salty foods is also a physiologic response to a possible lack of sodium. If the body doesn't get enough sodium, which can happen during starvation for example, you will actually secrete very little sodium through the urine. Human physiology is simply amazing like that.
Salt is sodium chloride, both of which are utilized by the body. Potassium can be found in meat, but its concentration is very tightly regulated by the body. Magnesium, calcium and other elements can be obtained mostly from... water, which might be a problem in some areas admittedly. Ancient humans had to worry about parasites, but water pollution, not so much.
Salting is especially important during the initial phases of any ketogenic diet because a rapid insulin decrease leads to an increase in the loss of sodium through the kidneys. This is known as 'keto flu' and can be avoided with salting to taste and drinking regular water.
See I just listen to my cravings when it comes to salt and it usually works out okay. If I feel like the meat is bland, I’ll add more salt. But wouldn’t cravings for fruit mean that your body wants more potassium or glucose? Or could it want an insulin spike to balance your electrolytes?
This is difficult to say for certain, since cravings can be hijacked by addictive substances...like fructose. You really could be defficient in potassium, which I find unlikely unless some other pathology is involved, or our lizard brain might just want that sweet sugar rush.
Great talk, gotta go sleep now.
