9-Keel Unified Theory Series: Chronic Fatigue Syndrome

This work is part of the 9-Keel Unified Theory Series, presenting a unified theoretical interpretation of Chronic Fatigue Syndrome (CFS) and Fibromyalgia through the systemic application of the TOFD framework. Unlike previous papers focused on specific organ systems, this work addresses the systemic energy imbalance that defines chronic exhaustion. It introduces the "Power-Save Mode" hypothesis, framing CFS as a protective adaptive response when Total Functional Deficit (TOFD) consistently exceeds systemic capacity, to prevent irreversible cellular collapse. This model demonstrates how localized tissue deficits accumulate into systemic debt, explaining multifaceted symptoms such as brain fog, post-exertional malaise, and chronic pain. Strictly adhering to the Cell Innocence Principle, it refutes "psychosomatic" narratives by showing fatigue is a verifiable physiological outcome of resource imbalance at the cellular level. This work concludes by offering a unified framework focused on reducing functional deficit and enhancing systemic capacity. The full foundational principles of the 9-Keel Unified Theory are detailed in the series overview paper.
