What is the Origin of Metabolic Decay?

The concept of metabolic decay is central to gerontology and metabolic medicine, rooted in the observation that the body's capacity to process energy and maintain tissue integrity diminishes over time. The term "Decay" underscores the systemic nature of this deterioration, moving beyond simple weight gain to encompass the fundamental breakdown of cellular energy production and signaling pathways. It is a key target for longevity interventions.

What is the Mechanism of Metabolic Decay?

The primary mechanism involves accumulated damage to the mitochondria, which are the cell's energy generators, leading to reduced ATP production and increased reactive oxygen species. Furthermore, age-related changes in adipokine signaling and chronic exposure to elevated glucose levels drive insulin receptor desensitization. Clinical strategies to counteract this involve enhancing mitochondrial biogenesis, improving insulin sensitivity through lifestyle and pharmacological agents, and reducing systemic inflammation to restore metabolic flexibility.

Metabolic Decay

Meaning

Metabolic Decay is the clinical term describing the progressive, age-related decline in the efficiency and robustness of fundamental biological processes, resulting in a reduced basal metabolic rate and impaired energy homeostasis. This physiological decline is characterized by decreased mitochondrial function, increased insulin resistance, and a chronic, low-grade inflammatory state. The clinical consequence is an increased propensity for fat accumulation, sarcopenia, and chronic disease development.
