How much water should I drink during my fast?

You need more water while fasting because you lose glycogen and, consequently, fluids, electrolytes, and salts. Consuming 2-3 liters of water daily while fasting is recommended to prevent dehydration and kidney stones. Adding electrolytes and sea salt is crucial to avoid keto fatigue, keto flu, and weakness. A daily intake of 1-1.5 teaspoons of sea salt is suggested, with more needed if you exercise.
