What Physiological Changes Occur During Fasting?

Fasting, the act of abstaining from food and in some cases drink for a specific duration, has notable effects on the human body.

It triggers a metabolic shift from burning glycogen to utilizing stored fat for energy.

This results in increased ketone production, serving as a crucial energy source, particularly for the brain.

Additionally, extended fasting initiates cellular recycling through a process known as autophagy.

During this process, old and dysfunctional cellular components are broken down and repurposed, contributing to overall well-being and health.

Fasting also promotes increased insulin sensitivity, which, in turn, may help manage blood sugar levels and reduce the risk of type 2 diabetes.

It further stimulates the production of Human Growth Hormone (HGH), influencing metabolism, body composition, and muscle growth.

Furthermore, fasting triggers processes that aid in cell repair, gene expression alteration, and immune system rejuvenation by fostering stem cell production.

Though fasting presents various potential health benefits, caution is advised for individuals with certain health conditions, pregnant or breastfeeding women, and those with a history of eating disorders.

Before embarking on prolonged fasts, it is essential to seek medical advice.

Overall, fasting can lead to a spectrum of physiological changes that significantly impact overall well-being and health.
