What is Intermittent Fasting?

Intermittent fasting is a fad but it seems that this craze can go for long because of its staggering health benefits. In this fasting, one needs to fast for a period of time per day or alternate days for as long as they want. The day is divided into two parts. In one part, one needs to fast and on the other part, one needs to eat as normal. The duration of fasting is from twelve to thirty-six hours.

Intermittent fasting Science:

Intermittent fasting helps in lowering insulin levels in the body. Carbohydrates are broken down into sugar glucose that our body uses as a source of energy. If the body doesn't use it then it stores it in fat cells or as fat. When the human body is on fast, its insulin level gets down and these fat cells release stored glucose that provides energy. So, the science behind intermittent fasting is to lower insulin levels to the extent that body fats start releasing stored sugar for energy and thus burn body fats.

How to Do Intermittent Fasting?

There are different methods to do intermittent fasting and one can choose a method that suits them. The following methods are commonly used to do intermittent fasting:

Intermittent Fasting 16/8:

This is the most famous type of intermittent fasting. In 16/8 intermittent fasting, One needs to do fast for 16 hours and then eat normally for 8 hours. He/She can take up to all-day calories in these hours with 2-3 meals. This fasting can be done daily or on alternate days or a couple of days a week.

Intermittent Fasting 12/12:

If someone can't cope with 16/8 intermittent fasting then he/she can do 12/12 'IF'. In this fasting, one needs to fast for 12 hours and eat normally on the other 12 hours. Again, this intermittent fasting can be done daily or on alternate days or on a few days per week. When the body gets used to it then one can increase the number of fasting hours and days per week.

Intermittent Fasting 14/10:

In this method, when the body gets used to 12/12 intermittent fasting then one can increase two more hours of the fasting period and can eat 10 hours as normal.

In this fasting, one can eat normally for 5 days a week and can have fast for 2 days a week. In these two days of fasting, one can eat but not more than 600 calories. Fasting for 2 days can be hard, so, many people go for the above three methods.

Eat-Stop-Eat Intermittent Fasting:

In eat-stop-eat intermittent fasting, one can fast for the whole day and then eat as normal. This method is recommended to do once or twice a week.
