Even protein distribution plus exercise for people awaiting liver transplant
Official title: Evaluation of Protein Distribution Optimization With Exercise Regimen on Nutritional Status, Body Composition and Functional Status in Patients Awaiting Liver Transplantation: The POWER-LT Randomized Clinical Trial
Run by Agricultural University of Athens · NCT07561138 · Data updated 2026-11-12
This trial tests whether spreading daily protein evenly and combining it with a 12-week exercise program improves nutrition, muscle mass, and function in people waiting for a liver transplant compared with uneven protein timing or usual advice.

Is this trial a fit for you?
✓Likely a good fit
Adults with end-stage liver disease or cirrhosis who are referred for or listed for liver transplantation, have an expected wait of at least three months, have not received prior formal dietary advice, can safely exercise, and can provide informed consent are ideal candidates.
✕Probably not a fit
Patients with exercise contraindications (for example recent variceal bleeding, severe encephalopathy, refractory ascites), chronic kidney disease requiring protein restriction, very short expected wait or life expectancy under three months, pregnancy, or inability to adhere to the program are unlikely to benefit.

What this trial studies
This randomized controlled trial enrolls liver transplant candidates and assigns them to one of three 12-week approaches: an even protein distribution diet plus supervised exercise, a skewed protein distribution diet plus the same exercise program, or standard dietary and physical activity advice. Primary outcomes include nutritional status, body composition, and functional status, while secondary outcomes cover anthropometry, laboratory parameters, quality of life, disease severity, complications, and mortality. For participants who undergo transplantation, the study will also record postoperative outcomes such as ICU and hospital length of stay, ventilation duration, complications, readmissions, reoperations, and mortality. Interventions are delivered at clinical sites in Athens with regular follow-up visits and objective measures of muscle and function.
Why it matters
Potential benefit: If successful, this approach could strengthen nutrition and muscle mass before transplant and potentially reduce postoperative complications and shorten recovery.
How similar studies have gone: Even protein distribution has been shown to boost muscle protein synthesis in healthy adults and exercise prehabilitation has benefited other surgical populations, but randomized data specifically in end-stage liver disease are limited.
