Personalized Dietary Feedback to Reduce Hepatic Steatosis in Patients With MASLD (PERSOMA)

27 oktober 2026 bijgewerkt door: Georg Semmler, Medical University of Vienna

Effect of Personalized Dietary and Lifestyle Feedback on Hepatic Steatosis in Patients With Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD): A Prospective, Randomized Controlled Trial

Metabolic dysfunction-associated steatotic liver disease (MASLD) and combined metabolic dysfunction and alcohol-associated liver disease (MetALD) are common chronic liver diseases associated with metabolic dysfunction and an increased risk of liver-related and cardiovascular complications. Lifestyle modification, particularly dietary changes and increased physical activity, represents a cornerstone of treatment. However, general lifestyle recommendations are often insufficient to achieve sustained improvements.

This prospective, randomized controlled trial aims to investigate whether personalized dietary and lifestyle feedback based on a structured questionnaire is more effective in reducing hepatic steatosis than generic lifestyle recommendations.

A total of 174 patients with MASLD or MetALD will be randomized 1:1 to receive either personalized or generic written feedback at baseline and after 2, 4, and 6 months. Changes in hepatic steatosis, assessed by the controlled attenuation parameter (CAP), will be evaluated over a six-month period.

Gedetailleerde beschrijving

This is a prospective, single-center, randomized controlled trial designed to evaluate the effectiveness of personalized dietary and lifestyle feedback compared with generic recommendations in patients with metabolic dysfunction-associated steatotic liver disease (MASLD) or metabolic dysfunction and alcohol-associated liver disease (MetALD).

A total of 174 adult patients with MASLD or MetALD will be randomized in a 1:1 ratio to an intervention group receiving individualized feedback based on a structured dietary and lifestyle questionnaire or a control group receiving standardized written recommendations.

Participants will complete the questionnaire at baseline and after 2, 4, and 6 months, followed by the corresponding written feedback. Clinical, anthropometric, laboratory, and non-invasive liver assessments, including vibration-controlled transient elastography (VCTE) and controlled attenuation parameter (CAP), will be performed at baseline and after six months.

The primary objective is to compare hepatic steatosis between the two groups after six months, adjusting for baseline CAP values. Secondary objectives include assessing changes in body weight, metabolic parameters, liver stiffness, dietary habits, physical activity, and health-related quality of life.

The study aims to determine whether a simple, scalable, personalized feedback approach can improve lifestyle management in patients with MASLD or MetALD.

Experimenteel: Personalized Dietary Feedback

Participants will receive personalized written dietary feedback based on their individual responses to a structured questionnaire. The feedback will include tailored recommendations regarding dietary habits. Updated personalized feedback will be provided at baseline and after 2, 4, and 6 months.

Participants receive individualized written dietary feedback based on their responses to a structured dietary questionnaire. The feedback includes an assessment of individual dietary habits, a visual representation of dietary patterns, and personalized recommendations to improve food choices and dietary quality. Updated feedback is provided at baseline and after 2, 4, and 6 months based on repeated questionnaire assessments.

Actieve vergelijker: Generic Dietary Feedback

Participants will receive standardized written dietary recommendations independent of their individual questionnaire responses. Generic feedback will be provided at baseline and after 2, 4, and 6 months.

Participants receive standardized written dietary recommendations based on general nutritional guidelines. The information is identical for all participants in the control group and is not tailored to individual dietary habits or questionnaire responses. The same generic dietary information is provided at baseline and after 2, 4, and 6 months.

Hepatic Steatosis at 6 Months, Assessed by Controlled Attenuation Parameter (CAP) Using Vibration-Controlled Transient Elastography (VCTE)
Tijdsspanne: 6 months (baseline CAP used for adjustment).

Hepatic steatosis will be quantified using the controlled attenuation parameter (CAP), measured in decibels per meter (dB/m) by vibration-controlled transient elastography (VCTE). The outcome measure is the CAP value at 6 months. The between-group difference at 6 months will be evaluated using analysis of covariance (ANCOVA), with baseline CAP included as a covariate. CAP is the only measurement reported for this outcome.
