A Nutrigenetic Intervention in MASLD
Sponsor: Maastricht University
Summary
The study is designed as a 12-week randomized controlled dietary intervention in individuals who had been diagnosed with NAFLD in the last 6 months and whose body mass index is above 25 at the time of participation in the pre-screening. The study sample is determined as 150 subjects and randomization will be done by stratification according to PNPLA3 genotype. At baseline, hepatic steatosis and fibrosis will be measured with Fibroscan, body composition will be analyzed, and transaminases and sugar and lipid metabolism indicators will be examined. The study will be conducted in parallel groups, with each group receiving equal amounts and intensity of Mediterranean diet or low-fat diet therapy. At the end of the 12-week intervention, baseline measurements will be repeated and the efficacy of the Mediterranean Diet and Low-fat diet therapies will be compared, as well as the effect of PNPLA3 mutation on intrahepatic response will be analyzed.

Dietary intervention
The dietary intervention is a personalized counselling programme implemented in form of a moderate caloric restriction (≈500 kcal/day) to allow for a moderate weight loss (≈5% BW). Each participant will be invited for consultation visits to a study dietitian, lasting up to 30 minutes. During the sessions, participants will be provided with written information material that explains the principles of diet in concern. Dietary interventions for both groups will be standardized in terms of education and one-on-one counseling. Education and dietary prescription will be individualized by the study dietitians within the diet-specific recommendations, to allow for personal food preferences. All subjects will receive equivalent intensity of care in terms of opportunities for contact and availability of individual dietary counseling. Motivational interviewing techniques and behavior change techniques will be adopted by study dietitians to ensure long-term maintenance of dietary modification.
