Hour 8
Liver Glycogen Depleting
Roughly one full sleep cycle in. Your liver is doing the heavy lifting to keep things stable.
What's Happening
The liver's glycogen stores are being actively consumed to keep blood glucose stable. Fat cells are beginning to release fatty acids into the bloodstream as a backup fuel. Ketone production is still minimal but the switch is in progress.
How You're Feeling
Hunger is more present now. Some people feel a light headache or fatigue — this is normal metabolic adjustment, not danger. Staying occupied helps significantly.
