YOGYAKARTA - When a person performs fasting, the body will experience biological phases that are very beneficial for health. Starting from detoxification to recovery, see several phases that the body goes through when fasting below.

In addition to providing opportunities for the body to rest and restore organ function, fasting for one day can also improve the immune system.

The detoxification process that occurs during fasting will help the body clean up toxins and increase health significantly.

In addition, fasting is also proven to provide benefits for reducing inflammation, increasing insulin sensitivity, and improving heart health.

In the long term, regular fasting will bring many benefits to the health of the body.

These benefits can also be achieved by body phases when faced with fasting conditions, these phases include:

In the early phase of fasting which lasted for 0 to 4 hours after the last meal, the body began to experience significant changes.

Blood glucose levels began to increase due to the digestive process and the absorption of foods previously consumed.

In response to the increase in glucose levels, the pancreas produces insulin that works to regulate blood sugar, providing stable energy for body cells.

During this period, there have been changes in hormones related to appetite.

Turmon grerlin, also known as the hunger hormone, tends to decline within 1-2 hours after eating.

Meanwhile, leptin levels, hormones that signal fullness, begin to increase. This process will help maintain a stable level of energy between eating time and providing a sense of fullness so that individuals do not feel excessive hunger.

After going through the initial phase, the body will enter the catabolic phase which lasts between 4 and 16 hours of fasting.

At this stage, the body begins to take advantage of all the nutrients stored as energy. Glikogens stored in the liver and muscles will be broken down and used to meet energy needs.

Along with reduced storage of glycogen, the body switches to using fat as a source of energy.

This process makes fat burning an important advantage when fasting. However, the length of time it takes to reach this fat burning phase depends on the previous food intake.

The higher carbohydrate consumption, the longer it will take to burn the deposit.

Therefore, people who are fasting must pay attention to the macronutrients consumed in their daily food.

After the body fasts for 16 hours, there will be a significant increase in ketone production.

Keton is produced as a result of fat burning, making it an alternative source of energy.

Under normal conditions, the concentration of ketones in plasma is between 0.05 and 0.1 mM, but when fasting or reducing carbohydrates in a diet, this concentration will increase to 5-7 mM.

Light physical activity, such as walking or cycling, can accelerate the production process of keton.

Weight reduction and reduced risk of some diseases, such as diabetes and heart disease, can occur in this phase.

During the process, the body that adapts to using fat as an energy source, long-term benefits for health begin to appear.

After 24 hours of fasting, the body will enter the autofagi process, the cells will recycle the old components and break down damaged or misfolding proteins.

This process is very important for the process of rejuvenation of cells and networks, helping to eliminate malfunctioning cellular components.

In addition, autophages have an important role in preventing neurodegenerative diseases related to aging.

In this phase, insulin levels began to decline, and the body was forced to take advantage of alternative energy sources.

When glucose deposits run out, the body focuses energy on repair and cell regeneration because it activates the autofagi mechanism.

Therefore, the health benefits of this medium-term fasting become highly therapeutic.

In a diet that uses fasting methods, such as intermittent fasting, not eating for more than 48 hours is one of the diets that can be done.

Fasting, which is continued for more than 48 hours, is referred to as long-term fasting. In this phase, insulin levels continue to decline, while keton concentration increases as the main energy source for the body.

The use of fat as an energy source makes the body able to maintain muscle mass while burning fat efficiently.

Studies conclude that prolonged fasting can have a positive impact on health, namely lowering blood sugar levels and blood pressure, and reducing belly fats.

However, long-term fasting must also be done with medical supervision, because certain individuals can pose risks.

It is important for everyone to understand that the health benefits obtained from prolonged fasting cannot be equated with daily fasting.

That's the explanation of the phase that the body goes through when fasting. Hopefully useful! Visit VOI.id to get other interesting information.
