Body Changes After 3 Days of Water Fasting

When you don't eat for three days and only drink water, your body goes through big changes.

At first, your body uses up all the sugar stored in your liver.

After that, it starts breaking down fat to make energy, which can make you feel tired or dizzy.

Your brain starts using a different kind of energy called ketones.

But this can also cause headaches and make it hard to think.

Your muscles might also shrink a little.

Some people say fasting helps your body repair itself, but doctors warn it can be dangerous, especially for people with health problems.

It's better to eat healthy and exercise regularly instead of fasting for a long time.
