This is the ultimate guide to intermittent fasting for beginners.

What is Intermittent Fasting?

Since human evolution, deliberate or unintentional fasting has been carried out by people due to famine or as part of some rituals. Hence, fasting is not a new term for humans. And we have developed to be able to function without food for extended periods of time. Unlike other dietary patterns, intermittent fasting follows a specific time pattern for eating. It’s all about when you eat not what you eat. When you practise intermittent fasting, you are supposed to eat during certain times only. 

In intermittent fasting, these eating gaps are part of our dietary decisions. Fasting for a specific number of hours per day or eating just one meal a couple of days a week can help your body burn fat. Be it a 16:8, 14:10 eating time proportion or Eat-Stop-Eat method, you must be consistent to get better results. 

Types of Intermittent Fasting

There are different intermittent fasting schedules and types. You can follow the one that suits your comfort.

16:8 Approach

Though there are different patterns of intermittent fasting, the most common type is the 16:8 approach, in which you can eat during day time for 8 hours and fast for 16 hours till the next first meal of the day. Health experts suggest keeping the eating windows in the early hours of the day for great benefits. Though this is the best approach that brings maximum benefits, beginners can follow the 14:10 ratio because a sudden change in the dietary pattern can sometimes adversely affect your digestion. 

5:2 Diet

This is another intermittent fasting approach, wherein you can eat regularly for five days of the week, restricting high-calorie (500-600 calories) intake on 2 non-consecutive days.

Alternate-Day Fasting

In the alternate-day fasting approach, you fast only on alternate days. Fast every other day with zero-calorie or restricted calorie intake. That is, you can eat 24-hours today, fasting 24-hours fasting tomorrow; likewise the whole week. To be more precise, in alternate-day fasting, you can follow a low-calorie normal diet on alternative days. 


Eat-stop-eat is another type of intermittent fasting, which allows you to fast for 24 hours, once or twice a week. In simple words, you are not supposed to eat after your dinner until the next dinner the following day.

Benefits of Intermittent Fasting

Intermittent fasting is not about eating whole food, raw fruits or practising any specific diet. It’s simply scheduling your meals’ timing increasing a long gap between the last meal of the day and the first meal of the next day. Beneficial changes are seen related to the longevity seen in genes.

9 am to 5 pm
