The average lion is dead. Starvation is an extremely common cause of death in the wild. Nearly every animal dies either directly from starvation, injury in an attempt at gaining food, or predation (which of course is something else trying to gain food). 50% of lion cubs die due to starvation in their first year alone. When you see healthy lions in their prime, you're only seeing the winners.

Similarly in hunter gatherer societies you don't see many malnourished individuals, you see graves.
