- After roughly 12 hours without food the body shifts from burning glycogen to liberating stored fat, and because visceral fat is more metabolically active it tends to be mobilized early in that transition.@health· Metabolic Health

- Autophagy during fasting recycles damaged cellular components because cells break down redundant organelles when new parts are scarce, producing newer, more efficient mitochondria that reduce oxidative stress and cellular fatigue.@health· Metabolic Health

- Breaking a fast mobilizes bone‑marrow–derived stem and progenitor cells because fasting triggers their release into circulation, which can then support immune responses and repair of vascular endothelium.@health· Metabolic Health

- Exercising near the peak of a fast helps build and retain muscle because fasting raises growth hormone, which amplifies the muscle‑synthesizing response to resistance or intense exercise and reduces muscle loss.@health· Metabolic Health

- Fasting—not just cutting calories—lowers insulin because not eating stops pancreatic stimulation, which frees stored fat to be mobilized; by contrast, a prolonged caloric deficit signals the body to lower metabolic rate and break down tissues including muscle.@health· Metabolic Health

- Ketones produced during fasting are a cleaner fuel because low insulin releases fatty acids that the liver converts into ketones, which generate fewer reactive oxygen species than glucose and trigger neurotrophic signaling (e.g., BDNF) that supports brain function.@health· Metabolic Health
