A Nutrigenetic Intervention in MASLD

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.
