What is intermittent fasting?

Intermittent fasting is an eating schedule that switches between fasting and eating on a normal schedule. Many diets focus on what to eat but intermittent fasting focuses on when to eat. With intermittent fasting you only eat during a specific time and fast for a certain number of hours each day.


Science reveals that our bodies have evolved to be able to go without food for many hours, or even several days. There are several ways to intermittent fast but they are all based on choosing regular time periods to eat and fast. After hours without food the human body naturally exhausts its sugar store and starts burning excess fat.


Here are some of the intermittent fasting approaches:

  • 5:2 approach which involves eating regularly 5 days a week but for the other 2 days you limit yourself to one 500-600 calorie meal.

  • Daily approach which restricts daily eating to one 6 to 8 hour period each day.


Intermittent fasting is not going without food for 24,36,48 or even 72 hours. Going without food for too long can actually encourage your body to start storing more fat in response to starvation.


There are many benefits to intermittent fasting, such as:

  • Boosting visual memory in adults

  • Improved blood pressure and resting heart rates

  • Fat loss while maintaining muscle mass

  • Prevents obesity

  • Reduces tissue damage in surgery and improves results


Intermittent fasting may have different effects on different people. You should consult your doctor before you start intermittent fasting to make sure it is safe for you.
