The effect of fasting on the human body

There is no doubt that fasting has an effect on the fasting person physically, in addition to the religious and social aspects, know the most important of these effects.

During fasting hours, the fasting person feels hungry and feels a lack of energy that the body needs in order to continue its daily activities as usual.

In order to understand the effect of fasting on the human body it is important to know what chemical reactions are taking place in the body. Chemical reactions are the pace, or length of time, that the body needs in order for the food we eat to convert into thermal energy in the body.

The body converts food into glucose (mono sugar) and thus gets the energy it needs to carry on with its daily activities.

The amount of this energy varies from person to person, from one health condition to another, especially in cases of illness.

Chemical reactions

It is important to know that everyone has a basic energy that is appropriate for him, and without which he cannot live - it is called BMR, which is the amount of basic heat energy that the human body needs in a state of rest - that is, without making any physical effort - through which it can maintain chemical reactions. In the body, that is, energy that is supplied to the brain, nerves, kidneys, etc.

These chemical reactions are related to several factors, including:

Body structure: the larger the muscle, the greater.

Gender: It is greater in men.

Age: with the passage of years, the chemical reaction in the body decreases.

Nutrition: It is related to the composition and distribution of meals during the day.

Physical activity: increases the chemical reaction.

There is no doubt that the human body can adapt and follow a specific chemical pathway to ensure its continued ability to perform, without food for a specific period of time.

What are the changes during fasting?

A lot of research has proven that BMR (the amount of basic thermal energy needed by the human body in a state of rest) decreases by 1% every day during fasting until it reaches 75% of its normal value, that is, the amount of energy that a person needs during fasting is less than Those he needs on normal days.

In general, weight decreases as a result of fasting and following proper nutritional advice for fasting. In the case of eating too much foods rich in fat and sugars, the weight increases.

Low weight has a positive effect on blood pressure balance, diabetes, fatty liver and other diseases.

During fasting hours, the level of sugar in the blood decreases, which leads to a decrease in the level of the hormone insulin, thus the secretion of the hormone glucagon (Glucagon), which divides the chlorine (sugar available in the liver) in order to convert it into energy instead of glucose (sugar from food).

During the first days of fasting, the level of cholesterol in the blood decreases, but soon, over time, it returns to its pre-fasting level.

As for the fats and the effect of fasting on them, this relates to the type of foods that the fasting person eats during the holy month. When consuming foods rich in fat and sugars, their proportion increases significantly.

Fasting has many benefits, but also risks. Therefore, it is advised to follow appropriate nutritional advice and consult a doctor in case of fatigue, extreme fatigue, or the appearance of any other symptoms that cause suspicion.

What is the effect of fasting on the body?

So after we understand the mechanism behind the changes that occur in the body during fasting, we must understand the effect of fasting on our bodies!

Here are the following points that summarize this effect:

The body always needs energy in order to be able to operate all of the body's organs and systems, so when eating, the processes and functions of these devices walk exactly as they are supposed to.

In case of fasting, the work and activity of the digestive system decreases significantly and significantly, as the level of excretion of sour materials decreases and the movement of the stomach and intestine decreases greatly.

The heart and its work are affected by the state of the body, in other words, the activity of the heart depends on blood pressure and its volume in the body, and since the blood is mainly composed of water, its volume decreases during fasting, thus affecting the work of the heart.

The respiratory process is also related to the work of the heart, that is, to the general condition of the body and the rate of metabolic processes, to accordingly reduce the work of the respiratory system but slightly, not seriously, or harmful.

The matter does not apply to the work of the kidneys and liver, as the burden on them may increase during fasting hours, as the liver is required to provide the energy sources necessary for the body to increase its work during fasting, in contrast, its work in filtering toxins and harmful substances that enter our bodies usually through food is reduced.

With regard to the kidneys, which work to control the level of water whose quantity decreases during fasting, it tries to control the urination process during these hours so that it tries to ensure that the amount of urine leaving the body does not exceed the amount of water contained in it
