Intermittent fasting: a short guide

Our modern weight loss world offers an enormous number of dietary plans – all of them promise you incredible results. Of these, intermittent fasting is one that is listed among the most popular diets. The idea is that you do not eat on certain periods of time daily (4).

Such a diet helps to trim off unwanted pounds as you significantly limit your calorie intake, and at the same time, improve your overall health metrics. Along with physical exercises on a regular basis, it could cause the lowering of your risks for diabetes and even some types of cancer. According to some evidence, it could also improve one’s health related to such medical conditions as stroke, asthma, multiple sclerosis, arthritis and more.

There are numerous approaches to this diet. For example, some dieters prefer following their regular meal plan five days a week and fast the other two days. Others fast every other day. Another widespread approach is to eat only during an 8-hour window of the day and fast the remaining 16 hours of the day.

Very often the followers of this dietary pattern are very careful with the start of their fasting day. They pay attention to their bodies and incorporate this lifestyle change very gently. Many people, though tend to neglect another important aspect – that it is as crucial to break the fast carefully and correctly as well.

First, it is important to understand that there are several types of fasts. There are long and short fasts which are based on length of time. A 12-24-hour long fasting period is considered to be short-term, and the one which lasts for more than 36 hours, is a long-term one. These have different effects on your body.

You experience a short-term fast almost every day, even if you don’t follow an intermittent fasting dietary pattern. This happens as you have the period between after eating your dinner until you have your first meal the next day. Such fasting has no specific impact on your body and digestive functions in particular. Breaking this type of fasting also doesn’t require any special approach or planning. However, longer-term fasting has a bit of a different effect on your body. During such fasts your body is more likely to decrease the amount of digestive enzymes produced by your digestive system. This is why returning to eating on this type of fast requires more attention and planning.

The work of your body during your fasting days

Let’s figure out more details about the work of your body during your fasting days. When you just start with your intermittent fasting journey, your body will need some time to adjust. During your usual diet, when you ate regularly, your body used metabolic energy to produce digestive enzymes to effectively process the foods you consumed. This all changes when you start practicing intermittent fasting. Your body just doesn’t need and therefore doesn’t produce the same amount of enzymes, and instead your metabolic energy is used for other functions in your body. Perhaps for this reason fasters often experience a burst of energy and have increased feelings of wellbeing (6).

Breaking a long-term fast can lead to a litany of side effects. When you start eating again after a prolonged period of fasting and after your body has slowed its production of enzymes down, you may notice bloating, stomach pains, diarrhea, nausea and more. This happens because your body doesn’t have necessary amounts of digestive enzymes to process the foods you eat, and so it stays in your stomach longer. At this time, your body needs a couple of hours or more to start digesting the food.

There are several efficient methods that can help you to minimize these side effects. First, it is important to fast on a regular basis. In this way, your body gets used to this dietary pattern and doesn’t cease producing enzymes. As a result of this, you won’t face such side effects at the end of your fasting period. Of course, after a certain period of practicing intermittent fasting of a nutrition type, you will be able to finish your fasts the way you like. But note that it is important to exercise caution during the very beginning of your new lifestyle (approximately first 2 months).

There have been such cases recorded among people who had little to no food before drinking high amounts of alcohol (1).
