During a fast, the body transitions from using glucose as its primary source of energy to utilizing stored fat. This metabolic shift occurs when the body exhausts its glycogen stores, typically within the first 24 to 48 hours of fasting. Once glycogen is depleted the body enters a state called ketosis, where it begins to break down fatty acids into ketones for fuel.
Fasting can take different forms including intermittent fasting, where individuals cycle between periods of eating and fasting and extended or prolonged fasting, which involves fasting for longer durations often for multiple days.
Many people choose to fast for health reasons. Fasting have various benefit such as weight loss, improved metabolic health, enhanced brain function, cellular repair, reduced inflammation and increased longevity. However it is necessary to note that the effect of fasting can vary among individual and that it may not be suitable for everyone, especially those with certain medical conditions.
