Metabolic Efficiency Aging

Meaning

Metabolic Efficiency Aging refers to the rate and functional quality of decline in the body’s intrinsic ability to efficiently process, utilize, and store energy substrates, including glucose, fat, and protein, as an individual progresses through the lifespan. A state of high metabolic efficiency in aging is clinically characterized by stable glucose homeostasis, high cellular insulin sensitivity, and optimal mitochondrial function, all of which collectively minimize systemic inflammation and cellular damage. Conversely, a significant decline in this efficiency is universally recognized as a primary, non-negotiable driver of major age-related diseases, including type 2 diabetes, obesity, and cardiovascular pathology, and is deeply linked to progressive endocrine dysfunction.
