  1. Metabolism shifts from using glucose as primary energy source to oxidation of fatty acids and ketone bodies
    Also true with a ketogenic diet
  2. Increases cellular autophagy, apoptosis, and stem cell production, while preventing development of senescent cells.
  3. Causes cells to clear away damaged mitochondria and recycle damaged components for energy (mitophagy) and create new mitochondria (mitochondrial biogenesis)
  4. Increases levels of nicotinamide adenine dinucleotide (NAD+), a cofactor for many enzymes
  5. Activates repair processes
    These can only happen in a fasted state, which is why they usually happen during sleep
  6. Improves blood sugar, insulin sensitivity, and blood lipids
  7. Improves inflammatory markers, including C-reactive protein and Tumor Necrosis Factor
  8. Improves adiponectin, leptin, and brain derived neurotrophic factor
