Abstract

Metabolic theories of aging postulate that aging is due to energy expenditure, which ultimately results in the breakdown and eventual death of cells. Historically, within the realm of metabolic theories of aging, there have been three models: The Rate-of-Living theory, The Oxidative Damage/Free Radical theory, and the Metabolic Stability theory. All three theories maintain that aging is directly related to metabolic rate, but the theories differ in how they arrive at that conclusion.
