High-protein, plant-dominant diet for people with liver cirrhosis

Evaluation of a High Protein Plant Dominant Diet (HiProPlaDo) in Sarcopenia, Quality of Life and Metabolic Parameters in Patients With Liver Cirrhosis: A Randomized Clinical Trial

NA · Agricultural University of Athens · NCT07028580

This 6-month test compares a high-protein, mostly plant-based diet to a usual low-fat animal-protein diet in adults with decompensated cirrhosis who are awaiting kidney transplant to see which better preserves nutrition and muscle.

What this trial studies

This is a randomized, double-blind, 6-month dietary intervention comparing a high-protein, plant-forward diet to a conventional low-fat animal-protein diet in adults with decompensated cirrhosis awaiting kidney transplantation. Participants are randomized to one of the two diet arms and receive guidance while researchers collect dietary recalls, food-frequency questionnaires, and activity and quality-of-life surveys. Clinical data include blood tests for inflammatory and nutritional markers, body-composition measures with emphasis on muscle mass, functional muscle assessments, and analysis of the intestinal microbiome. Primary outcomes cover liver function, nutritional status and malnutrition risk, body composition and sarcopenia, microbiome changes, and patient-reported quality of life.

Who should consider this trial

Good fit: Adults with decompensated liver cirrhosis who are awaiting kidney transplantation, are not already following a vegetarian diet, and have not previously received specialized dietary advice are the intended participants.

Not a fit: Patients with psychopathological illness, those already on a vegetarian diet, or those with hepatonephrotic syndrome requiring protein restriction are excluded and unlikely to benefit from this intervention.

Why it matters

Potential benefit: If successful, the high-protein plant-dominant approach could help preserve or increase muscle mass, reduce malnutrition, and improve quality of life and liver-related health in these patients.

How similar studies have performed: Observational studies and small trials have reported promising effects of higher protein intake and plant-focused diets on nutrition and muscle in liver disease, but large randomized data remain limited.
