Electrolyte Imbalance

Increasing sodium and chloride intake is the single most important intervention for keto flu. Addressing nutrient deficiencies that affect electrolyte levels will improve temperature regulation. When carbohydrate intake drops, glycogen stores are depleted and the water bound to them is excreted, causing rapid fluid loss. Potassium is the second critical electrolyte lost during keto adaptation. Fluid loss during the low-carb transition carries away significant electrolytes including potassium, magnesium, sodium, and chloride. Correcting the electrolyte disturbance restores normal cardiac electrical activity. Electrolyte disturbances are the underlying cause of acute cardiac rhythm instability in the described clinical scenario. Nutrient deficiencies disrupt electrolyte levels, impairing the body's ability to regulate temperature and sweat. Magnesium and chloride are also lost during keto adaptation and are partially addressed by sea salt and leafy greens. When electrolyte balance is compromised, the body loses its capacity to regulate temperature effectively, resulting in reduced sweating.
