The glycogen in the liver begins providing blood glucose. Muscle glycogen is used as fuel by the muscles, fat cells (adipose tissue) release fatty acids to manufacture ketone bodies in the liver and to be used by the brain as fuel, and body proteins are converted to glucose.
In short, the body's metabolism shifts to catabolic reactions.
If this continues for too long, you begin to see effects of starvation:
- Inadequate tear production
- Enlarged/tender liver
- Muscle atrophy
- Rashes, sores, or peeling skin
In short, deficiencies of energy, protein, iron, and zinc can really mess you up in the long term.
