Energy balance

Decreased mitochondrial biogenesis and dysregulated lipid oxidation lead to compromised skeletal muscle bioenergetic status (low ATP) and muscle wasting in early critical illness.

Early muscle loss in the ICU is driven by a failure of the muscle's energy factories (mitochondria) to produce ATP, not just by lack of movement. This metabolic shutdown prevents recovery even if nutrition is provided.
