What Is Happening In The Body During Fasting
Fasting has become an important part of my life. I have seen great results in both my spiritual and physical well-being. I have been fasting regularly, and I would like to talk about the physical processes that occur in the body during a fast. Understanding what your body needs helps you stay on track and achieve better results and benefits. People often ask questions like: Can I have tea or juice during fasting? Can I fast on smoothies? Can I have liquids like broths while I’m fasting? Let’s look at what is actually happening in the body during fasting.
The processes that occur during fasting are very important. On the second or third day, the body begins to use its own stored resources for energy. The body is very intelligent, and it starts by breaking down damaged or unhealthy cells that need to be eliminated. It also uses some fat cells, which release stem cells. These stem cells then travel to the organs that need them most and begin repairing damaged areas. It is a remarkable process where healing and renewal take place. This is called endogenous nourishment.
No Food Condition Is Crucial
However, all these processes can happen only when no external food is available. I know that if my body receives even a small amount of nourishment—such as smoothies, broths, or teas with sugar or milk—it will not begin the cleansing process of using its own resources. Instead, it will continue to expect food from outside sources.
Another principle that needs clarification is that the body is actually better off with no food at all than with only white bread, white rice, or any other single type of food. To break down something like white bread, which is difficult to digest, the body needs additional nutrients, minerals, and enzymes. In some developing countries, people become sick with dystrophy caused by malnutrition. They receive a small amount of food, but not the necessary vitamins and minerals. Their bodies cannot begin healing or renewal because they never go long enough without food to trigger the use of damaged cells for energy. As long as the body continues to receive poor-quality food from time to time, it cannot switch to endogenous nourishment. Over long periods, this leads to illness.
So, in order to receive the benefits of healing and renewal, I make sure to eliminate any external food intake. And of course, fasting is not done indefinitely; it always has a clear time frame. I have completed several 7-day fasts, and this short fast does not permanently harm the body.
It is important that no carbohydrates, proteins, or fats enter the body during a fast. I do not eat or drink anything except pure water. This is crucial for the health benefits. To get the most out of a fast, no food should be consumed during this period.
The Body Knows Best Where To Heal
During fasting, the body decides which organs need healing—we have little control over this process. Sometimes we begin a fast hoping that the body will heal what troubles us the most, but there is no guarantee it will address the issues we consider a priority. The body knows best where to begin and what needs the most attention. This is why it’s not a good idea to fast with the expectation that the body will follow our plans. But if we stay positive, trust the process, and most importantly trust God, we can receive the best results. We will not harm ourselves, and with regular practice, fasting can bring great improvements that not only address our health concerns but exceed our expectations.
