The Truth about Fasting: How It Works
https://youtu.be/350bk9Ph3akIf you're fasting for longer than a day, it's a good idea to take electrolytes – especially sodium, potassium, and magnesium. Your body has a small reserve of electrolytes stored in its tissues, but they deplete quickly, usually within the first 24-48 hours. Electrolytes are minerals that are essential for the normal functioning of your body’s systems and organs. When you run out of electrolytes, you could get headaches, muscle cramps, feel fatigued, etc. It can also be dangerous for your heart during prolonged fasts. Do your research!
