What is the Origin of Catabolism Reversal?

The concept is rooted in the principles of metabolism, which divides biological processes into catabolism (breaking down) and anabolism (building up). The term 'reversal' signifies a deliberate, managed change in the dominant metabolic direction, often through exogenous or endogenous signaling.

What is the Mechanism of Catabolism Reversal?

Reversing catabolism involves increasing the bioavailability and sensitivity to key anabolic signals, particularly growth hormone, insulin-like growth factor-1 (IGF-1), and androgens. These hormones stimulate protein synthesis and inhibit protein degradation by modulating gene expression and activating intracellular signaling pathways like the mTOR pathway. Concurrently, reducing chronic inflammatory signals and managing cortisol levels helps diminish the catabolic drive. This dual action is required to shift the net protein balance positively.

Catabolism Reversal

Meaning

Catabolism Reversal represents a targeted therapeutic and nutritional strategy aimed at shifting the body’s metabolic state from a net breakdown of complex molecules to a net synthesis, or anabolism. In a clinical context, this means actively mitigating the loss of lean body mass, such as muscle and bone, which is characteristic of aging and chronic stress. Achieving catabolism reversal is essential for preserving physical function, enhancing recovery, and promoting long-term vitality. This shift is a core objective in sarcopenia and frailty management.
