This randomised controlled trial compared higher-protein with medium-protein delivery in critically ill adults while keeping total energy delivery similar. The study addressed a growing area of interest in critical-care nutrition: whether protein dose, independent of calories, influences recovery and functional outcomes. Patients were assigned to a higher-protein target of approximately 1.8 g/kg/day or a medium-protein target of about 0.9 g/kg/day. The study also considered the interaction between nutrition and early rehabilitation. The findings are best interpreted as part of an evolving evidence base rather than proof that every critically ill patient should receive a high protein dose immediately. Timing, disease phase, organ function, renal replacement, tolerance and mobilisation all affect how protein is handled. This directly aligns with CritiCARE's dedicated nutrition and metabolism sessions on protein delivery, sarcopenia and early rehabilitation. For HCPs, the practical lesson is that protein prescription should be deliberate and monitored rather than driven by a single universal target. The study also highlights a crucial concept in modern ICU care: nutrition and mobilisation should be considered together. Prescribing protein without a plan for recovery and functional rehabilitation may not capture the full clinical objective.
