Metabolic Decline

Meaning

Metabolic decline refers to the progressive reduction in the efficiency and capacity of an organism’s fundamental biochemical processes that convert food into energy and building blocks. This age-related physiological shift is characterized by a decreased basal metabolic rate, impaired insulin sensitivity, and dysregulation of lipid and glucose homeostasis. The clinical manifestation of this decline often includes sarcopenia, visceral fat accumulation, and increased susceptibility to metabolic syndrome. Hormonal imbalances, particularly in thyroid and sex steroids, significantly contribute to this systemic deterioration.
