Keep in mind that you can easily disrupt your electrolyte balance by doing excessive cardio and drinking large volumes of water, that results in excessive urination. When I see people that want to shed weight quickly. I have a feeling that some tend to neglect too replenish with essential minerals. And skimp on the use of salt→iodine/sodium.
Certain prescription medicine's can exacerbate one's electrolyte balance, while doing excessive cardio. Without proper replenishment of electrolytes ie; ACE inhibitors can enhance sodium excretion with some people. Excessive sweating can cause sodium and chloride levels to drop. Which can bring on hyponatremia. Not good.
I emphasized more on the potential of sodium/chloride loss, as there's a possible disruption of Calcium, Magnesium, Phosphorous and Potassium also.
