Dietary Strategies for MASLD (Metabolic Dysfunction-Associated Steatotic Liver Disease)

Overview

This is a non-blinded, three-arm, parallel, 6-month randomized, longitudinal, and controlled intervention trial. designed to compare the effects of three dietary regimes (Mediterranean diet, low-carbohydrate diet and standard nutritional recommendations) on non-invasive parameters of fat accumulation and liver damage, including radiological and biochemical tests, in overweight or obese subjects with MASLD. Participants were enrollment and screening from the Liver Unit of the Department of Medical Sciences, University of Torino and randomly assigned to one of three groups: a low-carbohydrate diet, a mediterranean diet, or standard nutritional recommendations. All participants were submitted to the following assessments both at enrollment and at after 6 month at the end of the study: 3-day food record; the Medi-Lite score; anthropometric measurements (weight, height, BMI, waist and neck circumferences); fat mass, fat-free mass by bioelectrical impedance; hand-grip strength; energy expenditure by indirect calorimetry; blood pressure measurement; blood sampling for metabolic variables and biomarkers of liver damage and liver disease measures (Cap, Stiffness and Fib-4).

This is a three-arm, parallel-group, open-label randomized controlled trial designed to evaluate the effectiveness of three different nutritional interventions on non-invasive markers of liver damage, including radiological and biochemical assessments. Patients with MASLD were recruited from the Liver Unit of the Department of Medical Sciences, University of Torino. At baseline, participants were randomly assigned to one of the following three groups: A) Low-carb Diet (LCHO: 35-40% carbohydrates, 30% protein, 30-35% fats.) B) Mediterranean Diet (MeD: 50-60% carbohydrates, 15% protein, 25-35% fats ) C) Control group: standard nutritional recommendations The following evaluations were performed both at baseline and after 6 months at the and of the study: 3-day food record; the Medi-Lite score; anthropometric measurements (weight, height, BMI, waist and neck circumferences, fat mass, fat-free mass by bioelectrical impedance); hand-grip strength; energy expenditure by indirect calorimetry; blood pressure measurement; blood sampling for metabolic variables and biomarkers of liver damage and liver disease measures (Cap, Stiffness and Fib-4).
