Prolonged Fasting

Meaning

Prolonged Fasting is a structured, voluntary period of abstaining from all caloric intake, typically extending beyond 24 to 48 hours, where only water and non-caloric beverages are consumed. This metabolic intervention forces the body to shift its primary energy source from exogenous glucose to stored hepatic glycogen and subsequently to fat and ketone bodies. Clinically, this practice is studied for its potential to induce cellular autophagy, improve insulin sensitivity, and promote significant metabolic remodeling. Due to its profound physiological effects, prolonged fasting should be undertaken only with clinical supervision and careful monitoring.
