Fasting is an ancient practice in which you abstain from food and sometimes drink for a certain period of time. While it was previously known for its spiritual significance, today, fasting is recognized for its potential health benefits, including weight loss, better metabolic health, and increased mental clarity. However, one must be careful while fasting and consult an expert to avoid adverse effects.

Many people fast for varying periods of time. Intermittent Fasting This involves alternating periods of eating and fasting. It involves cycles of fasting, often for 16-24 hours, followed by periods of eating. Some people even fast for 48 or 72 hours. It has many health benefits but also some risks.

Here, take a look at some of its advantages and disadvantages 72 hour fast,

depletion of glycogen stores

During the first 24 hours of fasting, the body consumes glycogen stored in the liver and muscles for energy. This is stored as glucose and as it depletes, the body begins to shift its energy source from carbohydrates to fat. This depletion causes a metabolic switch in which the body uses alternative energy sources.

increased ketone production

After glycogen stores are depleted, which usually occurs after 24 to 48 hours of fasting, the liver begins to convert fatty acids into ketones which then provide an alternative fuel, especially for the brain. Ketosis is a state in which the body relies on ketones for energy which can increase mental clarity, reduce inflammation and aid weight loss.

Autophagy activation

After 48 hours, the process of autophagy becomes more active. Autophagy is the body’s natural way of removing damaged cells and regenerating new and healthy cells. This process is important for repairing and maintaining cells, preventing chronic diseases and promoting longevity.

Decreased insulin levels

Fasting causes a significant drop in insulin levels, which can have many benefits, especially for those who suffer from insulin resistance or type 2 diabetes. Lower insulin levels help burn fat, improve metabolic health and reduce the risk of chronic diseases associated with high insulin, such as heart disease and obesity.

increase in human growth hormone (HGH)

Fasting may increase levels of human growth hormone (HGH). HGH plays an important role in fat loss, muscle preservation, and overall metabolic health. Higher HGH levels during fasting may help maintain muscle mass while promoting fat utilization.

Resets the immune system

Prolonged fasting promotes the regeneration of the immune system. By triggering the breakdown of old and damaged immune cells, fasting helps in the production of new white blood cells, thereby improving immune function. This reset can be beneficial in strengthening the body’s defense system.

imbalance in electrolytes

One of the drawbacks of this method of fasting is the risk of electrolyte imbalances, particularly in sodium, potassium and magnesium levels. These imbalances can cause fatigue, dizziness and irregular heartbeat. It is important to monitor electrolyte levels and consider supplementation or medical supervision during prolonged fasting to prevent health complications.
