In this blog post you will get a complete description about Intermittent Fasting – Its complete description, benefits, methods, uses, process to follow and side effects. So Lets Get Started !

1. What Is Intermittent Fasting ?

You might have often heard about the term Intermittent Fasting. But do you actually know what it is ? Fasting is a very old technique which is being followed from several years. Fasting means to restrict yourself from food or any solid dietary particles for a fixed duration of time.

Many people opt to have a complete fast i.e without in-taking food as well as water. But that occurs very rarely and its not necessary to restrict your body to that limit. Getting restricted from food and solid dietary materials is enough for a complete fast and health gain.

Intermittent fasting is the type of fasting which is generally kept for 16 hours in one day duration ( 24 hours ). However, there are few techniques of intermittent fasting which we will discuss later. But if you want to keep a basic intermittent fasting then you have to keep a fasting period of 16 hours.

If you are willing to have a intermittent fasting then you have to restrict yourself from eating anything for 16 hours. You can perform this fasting for twice or thrice in a week.


2.1. 16 / 8 Fasting Method – 16 Hours Fasting

This is the most prevalent and famous type of intermittent fasting. In this type of intermittent fasting you have to keep a fasting window of 16 hours in 24 hours.

Most of the people generally skips their breakfast. So if you want to try this technique of fasting you can keep a fasting window from 9 pm to 1 pm. You can introduce four healthy light meals in the eating window of 8 hours remaining, that is from 1 pm to 9 pm.

You should keep your minimum protein intake, carbohydrate intake, fat ratio very well distributed and measured in this eating slot. Also, don’t forget to keep yourself properly hydrated. Have atleast 3 litres to 4 litres of water per day.

Many studies have suggested to opt for three basic meals during the period of 8 hours. But I will highly recommend you to have four small healthy balanced meal during this slot. This will keep you more energized and active during the whole day.

2.2. Complete Fasting 24 Hours Duration

This fasting includes a complete fasting period of 24 hours. If you are going to opt for this, then you will have to restrict yourself from eating anything for 24 hours duration that means one day.

You have to keep a cycle of one day fast that is either fasting from breakfast of previous day to the next day or fasting from dinner of previous day to the dinner of next day.

You can keep this type of fast twice in a week to improve your digestive potency of your body. Keeping complete fasting for more than twice in a week is not what I will recommend to you. Also, remember not to keep this type of fasting for consecutive days. Keep a gap duration of minimum 48 hours to 72 hours before adapting the next cycle of fasting.

However, if you start to feel tired or experience fatigues I highly recommend you to have fruit juices or liquid diet. Because it is when your body will start to send you signal that it needs a definite amount of glucose and nutrients to function properly.

2.3. Calorie Restriction

Your maintenance calorie should be your key goal in this type of diet restriction. Check your maintenance calorie before choosing this fasting plan.

When you will get your daily maintenance calorie, cut down to 80 %. It means if you got your maintenance calorie as 2000 Calories / day, then you will have to restrict your diet till 400 Calories/ day. If you have got your maintenance calorie as 3000 Calories/ day then you will have to have 600 calories/ day.

This diet plan you should follow twice in a week but not for consecutive days. Remaining 5 days in the week you can have your normal diet routine with your normal maintenance calorie requirements.

This restriction calorie fasting process is a great method for those who cannot opt for intermittent fasting or complete fasting for any reasons. Although, it is not that much effective as intermittent or complete fasting but still for the beginners it is a great step to choose and proceed forward.

Is intermittent fasting efficient every-time? No, it is not. If followed or adopted in a wrong way you will face side effects. Here are the few of them.


If you are a beginner you will feel great cravings during the fast period of 16 hours. To avoid this do not start to have a strict intermittent fasting plan from your Day 1. Rather give yourself time. Have very small meals and as days passes gradually try to increase your fasting time.

Your body won’t be able to resist your new changes suddenly. Hence, you need to transform slowly. This way you will feel less hunger and food cravings. Meanwhile if you feel cravings ( during your intermittent fasting period ) you can have a glass of fruit shake, a seasonal fruit, green tea or a small vegetable boiled platter.

This will decrease your cravings and won’t affect very much in your intermittent fasting.


This is the most common symptom in a intermittent fasting person. Headache arises due to Gastrointestinal problems during fasting period.

When you are a beginner, you might feel a headache quite often. Your stomach consist of gastric juice ( pepsin ) which gradually increase its acidity. This happens due to a long interval of time. Your body takes a month time to get acquainted with this fasting method.

This increase in acidity level causes a tinc of headache. To avoid this, the best remedy is to start intermittent fasting part wise. Do not begin with 16 hours. Try to start with 12 hours and gradually increase it. In couple of weeks you will reach 16 hours and won’t get affected with headache too much.


During your initial phase you might feel a great low energy. This is very obvious reason as you are unable to feed your body with proper nutrients, carbohydrates and good fats. But this symptom will be there in your body for first month.

Once your system gets habituated with intermittent fasting you will start taking it casually. In-case if you experience very low energy you can have a small amount nuts, lentils or sweet potato. These are good carbohydrates and fats source and will spike energy level in your body.

Remember, not to overdose or eat more. This way your body will not able to resist transition phase and you might feel uneasiness, stomach issues and indigestion.

TIP – This is a very basic but vital tip for all those you are performing fast. Never break your fast duration with a unhealthy diet. This will waste your overall fasting period and you won’t be benefited from it. Also remember to break your fast with a low, oil free, small quantity of diet. Overloading too much at a time will cause body imbalance.
