Intermittent fasting technique includes not eating anything for a particular measure of time. As the name suggests, it is an arrangement where you set a time frame in between the day. Basically, you cannot eat anything for at least 16 to 20 hours in a day. You eat between the other 4–8 long periods of the day. For the rest of the hours, you have to fast. You can have a low-calorie drink amid this. The more you fast, the better are your outcomes.
