Is Water Fasting Good for You or Dangerous?

Summary: Water fasting means drinking only water and eating no food for one to three days. Many people try it to lose weight or help their bodies clean out old cells, a neat trick called autophagy. Short fasts might even help lower your blood pressure and blood sugar.

However, water fasting can be very dangerous without a doctor's help. Believe it or not, you can actually get dehydrated because you get a lot of your daily water from the food you eat! You might also feel super dizzy when you stand up, lose muscle, or mess up the important minerals in your blood. Always talk to a doctor before trying a fast, and skip it entirely if you are pregnant or have kidney issues.
