About

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.

300 participants in 2 patient groups

Mediterranean Diet Group
Experimental group
Description:
The Mediterranean diet includes high amounts of olive oil, olives, fruits, vegetables, whole grains, legumes, nuts, a high intake of fish, moderate consumption of eggs, poultry, and dairy, and low consumption of red meat and products. The targeted macronutrient distribution is 40% of total energy from carbohydrates, approximately 20% from protein, and 40% from fats. The share of saturated fats in total energy will not exceed 10%. Participants will be provided with written resources, brochures explaining the Mediterranean diet, and information about the Mediterranean diet pyramid. A weekly menu will be planned for all participants, along with cooking tips. Participants in this group will receive a weekly food support package for 12 weeks, including essential elements of the Mediterranean diet such as olive oil, fish, nuts, and legumes.
Treatment:
Behavioral: Dietary intervention
Low Fat Diet Group
Active Comparator group
Description:
The type of diet to be followed in this group is based on the recommendations of the American Heart Association, the American Diabetes Association guidelines, and the Specific Nutrition Guide for Turkey. The targeted macronutrient distribution will be 50% of total energy from carbohydrates, approximately 20% from protein, and less than 30% from fats. The share of saturated fats in total energy will not exceed 10%. Participants will be provided with information notes and brochures explaining the low-fat diet. A weekly menu will be planned for all participants, and cooking tips will be provided. Participants in this group will receive a weekly food support package for 12 weeks, including low-fat dairy products, whole grains, and legumes, which are the essential elements of a low-fat diet.
Treatment:
Behavioral: Dietary intervention
