Fasting is abstinence, voluntary self-restraint from food. All people know the proverb: “fasting is not an aunt, but a mother.” Why were the ancients so respectful of fasting if, in theory, it brings death? Is there only negative in this phenomenon, or can fasting be beneficial? Let’s figure it out.
What is fasting?
Fasting is abstinence, voluntary self-restraint from food. Fasting can be a sacrifice of thanksgiving to God. Fasting can be a diet that excludes certain groups and types of foods. This is its main difference from the diet, which usually gives the recommended list of foods.
Fasting, like diet, can be extremely strict, and can – be quite free. However, intending to follow the traditions of fasting, whether soft or hard, it is necessary to consider the needs of your body. Whether he will be able to withstand this test – you do not know, so it is better to consult a nutritionist and try first a short and not too hard fast.

What are the different Types of Fasting?
Fasting is a dietary pattern that recommends alternating between periods of feeding and fasting. It does not impose a rule about what foods you should eat, but when you should eat them. There are several fasting methods, which divide the day or week into periods of feeding, better known as “food window” and fasting.
Various types of fasting include: –
1. During dry fasting
The person does not consume food or water and does not come into contact with water, although some people bathe in natural sources. The body is completely resting. Approximately on the third day of fasting, the body switches to endogenous (internal) nutrition and begins to eat its diseased cells.
2. When fasting on the water
Absolutely all food and drinks are excluded, only water remains. This fasting type is easier than others because water helps to quickly remove accumulated poisons and toxins from the body.
3. Cascade Fasting
Means alternating dry days with days on the water. This fast is ideal for training and preparing the body for dry fasting.
4. Periodic Fasting
Periodic Fasting is also known as intermittent fasting . Fasting is something that people have always practiced. In principle, it is about refraining from food, but it all goes a little deeper than that. Periodic fasting is an excellent tool for losing weight.
At the same time, it is practiced by those who want to lower their blood sugar, fight against tumor cells, or get in shape. You can do a lot of good for your body by regulating food intake in one way or another. Periodic fasting is an easy way to get all these benefits.
This is one of the most common forms of periodic fasting. As the name suggests, you abstain from food for a whole day. Then you can eat your meal. If you use intermittent fasting to lose weight, you should choose dishes that contain fewer calories. The goal is to limit your total calorie intake during the day, so avoid binge eating or huge portions.
16/8 periodic fasting
This periodic fast means that you are without food for 16 hours and then eat for eight hours. A person does not need to eat much more often than this. It is a simple yet effective way to fast. You can still train quite a lot and build your muscle mass.
Fasting certain days
the 5: 2 diet- Periodic fasting may include mixing the days when you eat. A popular form of this is the 5: 2 diet, developed by Michael Mosley, where you can eat food for two days but fast or eat much fewer calories for five days. If you choose to eat something these days, it should not exceed 500 calories.
5. Therapeutic fasting
Therapeutic fasting means that you do not eat food for more than 2 days, in principle no intake of carbohydrates is allowed. Some believe that the body’s energy stores are not burned until after 2 days of fasting and therefore advocate therapeutic fasting before periodic fasting.
What are the Health Benefits of Fasting?
When we haven’t eaten for a while, many things happen in our body. Here are some benefits of fasting that occur in the body during practice:

- Induces cell repair- Fasting triggers in the cells of the body a process of “removing waste” from cells called autophagy. This means that cells break down and metabolize broken and dysfunctional proteins that accumulate within them over time. Increased autophagy can provide protection against a variety of illnesses, including cancer and Alzheimer’s disease.
