Excess body fat provides a significant survival advantage during periods of sudden starvation
Excess body fat acts as an evolutionarily conserved energy reservoir that provides a vital survival advantage during periods of sudden starvation and food scarcity.
The retrieved literature consistently supports the claim that adipose tissue serves as a critical evolutionary adaptation and energy reserve for enduring starvation and food shortages.
