Anabolic Catabolic Index

Meaning

The Anabolic Catabolic Index (ACI) is a clinical metric designed to quantify the dynamic balance between the body’s building-up processes (anabolism) and breaking-down processes (catabolism) at a systemic level. This calculated ratio provides a vital snapshot of overall metabolic status, physiological resilience, and recovery capacity. A higher index suggests a favorable, dominant anabolic state, which is essential for tissue repair, muscle protein synthesis, and robust vitality. Conversely, a lower index indicates a prevailing catabolic dominance, a state often associated with chronic stress, muscle wasting, and accelerated biological aging.
