During Ramadan, Muslims abstain from eating 2 days a week. During the rest of the week, they eat normally. e.g. Ramadan, which lasts 30 days. They sit at the table only at night.

2. Fasting interrupted as it works

Longer fasting leads to the beginning of the process of breakdown of free fatty acids into ketone bodies, which are an alternative source of energy. Intermittent fasting helps to reduce the level of oxidative stress in the whole body (A. Li 2013). Interrupted fasting positively affects the digestive tract as it gives the body time to regenerate. No doubt a person needs food to live, but nowadays it is easier to understand the statement we live to eat. Food is an attractive element of business and social gatherings.

However, it is advisable to eat whole meals that will provide all the nutrients. On fasting days it is recommended to reach for fluids that do not provide energy. There are no restrictions on intermittent fasting. It is also important to ensure proper hydration during the fast. These can be water, herbal steams, unrefined coffee steams and tea. You can eat anything but only during the food window.

4. It's our health

In addition, interrupted fasting is most often adjusted to the daily rhythm (K. Pivovarova-Ramich 2019). The human biological clock is located in the subcutaneous region of the brain and responds to light stimuli. In the morning, cells are more sensitive to insulin, have better glucose tolerance, and have higher food thermogenesis compared to evening hours. In this study, Dr. Patterson and Dr. W. Hunt observed a decrease in the body's blood pressure during the later stages of the day, as well as an increase in the risk of developing low blood sugar as an alternative to fasting, which may lead to the use of long-term diets, a prolonged blood sugar cycle, and a reduction in the rate of heart disease. In 2012, Dr. R. M. Hunt published a study (E. L. Hunt, 2012), stating that reducing the body weight and body weight of a person's metabolic function during the lifetime of several days of the body is associated with a decreased metabolic rate, which can increase the function of the fasting body, and that can lead to an increased risk of

5. Intermittent fasting has its advantages

Intermittent fasting seems to be an effective way to lose weight, and it has many benefits, including improved lipid parameters and cell insulin sensitivity, which stabilizes the body's carbohydrate economy. It doesn't require a lot of time and work in the kitchen, and you don't have to weigh foods or deny yourself less healthy favorite snacks.

6. Intermittent fasting and defects

In addition, it is very common for a long period of fasting to result in a so-called Wolf Hunger. Unfortunately, interrupted fasting also has its disadvantages.

Not everyone will be able to maintain it, as persistent hunger may occur during the period of the fast.

7. Interrupted fasting for who?

Interrupted fasting may be used by healthy adults with normal body weight, overweight or obesity, and by athletes whose sporting disciplines require rapid weight reduction. Interrupt fasting is prohibited by: children and adolescents, elderly people, pregnant and breastfeeding women, women with menstrual disorders, diabetics, people suffering from nutritional problems such as anorexia and bulimia, those with cancer, kidney disease, liver disease, etc.

Rives 2019). When hunger occurs during fasting, it should not be ignored. After some time, the body will get used to fasting and hunger will appear less often. It should be done under the supervision of a specialist.

If someone decides to fast, they should start by prolonging the night fast.
