Hunger has five levels:
- Starving (0-49%) - HHP loss over time
- Very Hungry (50-79%) - no SHP regeneration
- Hungry (80-89%) - SHP regeneration
- Full (90-100%) - SHP regeneration
- Overstuffed (>100%) - Movement at crawl speed
Where the number is the number in brackets in the mouse over.
10 units of hunger represent 1%, thus a food that recovers 40 units of hunger will increase the bracketed number by 4%. 1% of hunger can replace 5% of stamina.
Lifting items will make you hungry faster. (Confirmed)
