Electrolyte balance is especially important for those on a low-carb or ketogenic diet. Switching to a keto lifestyle, with decreased carb and processed food intake, naturally lowers sodium levels and may also affect other electrolyte levels. This occurs because each gram of glycogen is stored in the body with 3 grams of water, and reducing carb intake uses up glycogen stores, causing the stored water to be removed.

An electrolyte imbalance can result in symptoms such as a racing heartbeat, heart palpitations, dizziness, weakness, leg cramping, constipation, bloating, and feeling shaky.
