Many people experience fatigue, headaches, or weakness on keto without realizing that electrolyte loss is often the root cause. Because low-carb diets reduce insulin levels, the body flushes out water and minerals more rapidly.This article explains the most common keto electrolyte imbalance symptoms and how to support mineral balance naturally.
Lower insulin levels cause increased water and sodium excretion. As water leaves the body, key electrolytes are lost.
These symptoms are often mistaken for “keto flu.”
Sodium supports nerve signaling and fluid balance. Too little sodium is one of the most common causes of early keto fatigue.
Potassium supports muscle and heart function, while magnesium supports relaxation, sleep, and muscle recovery.
Why are electrolytes important on keto?
Low-carb diets increase fluid loss, which can deplete electrolytes.
What are signs of electrolyte imbalance on keto?
Symptoms may include fatigue, headaches, muscle cramps, and dizziness.
Which electrolytes matter most on keto?
Sodium, potassium, and magnesium are especially important.
Can food help restore electrolytes?
Yes. Whole foods and mineral-rich options can help support electrolyte balance.
