Researchers are testing a new approach to treat fatty liver disease using a Mediterranean diet adapted for people outside Mediterranean regions, delivered through video calls with a dietitian and weekly text message support. According to research reviewed by Gram, this 12-week study will measure whether liver fat decreases using special MRI imaging that can see inside the liver. If successful, this remote, personalized approach could help millions of people improve their liver health without medication.

Researchers are testing whether a Mediterranean diet adapted for people outside Mediterranean regions can help treat fatty liver disease. The study uses video calls with a dietitian and text message reminders to help people stick to the diet. Fatty liver disease happens when fat builds up in the liver and can cause serious health problems. This 12-week study will measure whether the diet reduces liver fat using special imaging scans. If successful, this approach could help millions of people manage their liver health without surgery or medication.

Key Statistics

A 2026 randomized controlled trial protocol published in Trials will test whether a culturally adapted Mediterranean diet delivered through four video counseling sessions and weekly text messages reduces liver fat in adults with metabolic dysfunction-associated steatotic liver disease.

The study uses MRI-PDFF imaging, a specialized technique that precisely measures the percentage of fat in the liver, to assess whether the intervention reduces intrahepatic fat content by week 12.

This is the first randomized controlled trial to evaluate a fully remote, dietitian-led culturally adapted Mediterranean diet intervention using real-time video counseling and text-based behavior change techniques specifically designed for patients with fatty liver disease outside Mediterranean regions.

The Quick Take

  • What they studied: Whether a Mediterranean diet that’s customized for people who don’t normally eat Mediterranean food can reduce fat in the liver when delivered through video calls with a dietitian and supportive text messages.
  • Who participated: Adults diagnosed with metabolic dysfunction-associated steatotic liver disease (fatty liver disease) with confirmed fat buildup in their liver. The exact number of participants hasn’t been announced yet.
  • Key finding: This is a study protocol (a plan for research), not yet completed results. The study will measure whether liver fat decreases by week 12 using special MRI imaging that can see inside the liver.
  • What it means for you: If this study works, people with fatty liver disease may be able to improve their condition through diet alone, guided by a dietitian online. This could be especially helpful for people who can’t easily access in-person nutrition counseling.

The Research Details

This is a randomized controlled trial, which is the gold standard for testing whether a treatment works. Researchers will randomly assign adults with fatty liver disease into two groups: one group receives a customized Mediterranean diet program with video counseling and text message support, while the other group receives standard care. The intervention lasts 12 weeks and includes four video sessions with a registered dietitian (each 15-20 minutes long) at weeks 0, 3, 6, and 9. Between sessions, participants receive weekly text messages designed to help them stick to the diet and address their specific eating challenges.

The Mediterranean diet is being adapted specifically for people in non-Mediterranean regions (like Taiwan, where this study takes place) because the traditional Mediterranean diet includes foods that may not be familiar or available to everyone. The dietitian personalizes advice based on each person’s food photos and a Mediterranean diet adherence score. This customization is important because people are more likely to stick with diets that match their culture and food preferences.

The study measures success primarily by looking at how much liver fat decreases using a special MRI scan that can precisely measure fat inside the liver. Researchers also track liver enzymes, cholesterol levels, liver stiffness, gut bacteria, diet adherence, quality of life, and body measurements.

Most previous research on the Mediterranean diet and fatty liver disease was done in Mediterranean countries where people already eat this way. This study is important because it tests whether the diet works when it’s adapted for people in other parts of the world. Using video counseling and text messages makes the intervention scalable and accessible—it can reach many more people than in-person appointments. Understanding how to help people stick to healthy diets is crucial because diet adherence is often the biggest challenge in treating fatty liver disease.

This is a well-designed study protocol published in a peer-reviewed journal (Trials), which means experts have reviewed the plan. The study is registered at ClinicalTrials.gov, which increases transparency and prevents researchers from hiding negative results. The use of objective measurements (MRI imaging for liver fat) rather than self-reported data strengthens reliability. However, this is a single-center study in Taiwan, so results may not apply equally to all populations. The study is relatively short (12 weeks), so we won’t know about long-term effects yet.

What the Results Show

This article describes a study protocol—the plan for research—rather than actual results. The study hasn’t been completed yet, so we don’t have findings to report. The primary goal will be to measure the relative change in liver fat content using MRI-PDFF (a special imaging technique that measures fat percentage in the liver) at week 12. Researchers will compare how much liver fat decreases in the group receiving the customized Mediterranean diet intervention versus the standard care group.

The study will also examine secondary outcomes that provide a fuller picture of health improvements. These include changes in liver enzymes (which indicate liver damage), cholesterol and triglyceride levels, liver stiffness (which can indicate scarring), metabolic markers in the blood, gut bacteria composition, how well people stick to the diet, quality of life measures, and body weight and measurements.

Once results are published, they will show whether remote, dietitian-led Mediterranean diet counseling combined with text message support can effectively reduce liver fat in people outside Mediterranean regions. This information will help doctors and nutritionists decide whether to recommend this approach to their patients.

While primary results aren’t available yet, the study design shows researchers are interested in understanding how the Mediterranean diet affects multiple aspects of health beyond just liver fat. Measuring liver enzymes helps determine if the liver is healing and becoming less inflamed. Tracking cholesterol and triglycerides shows whether the diet improves overall cardiovascular health. Examining gut bacteria is important because emerging research suggests gut health is connected to liver disease. Measuring diet adherence helps researchers understand which aspects of the intervention work best for keeping people on track. Quality of life measures capture whether people feel better overall, not just whether their lab numbers improve.

The Mediterranean diet has strong evidence supporting its benefits for liver health from studies conducted in Mediterranean countries. However, Gram Research analysis shows that most previous research didn’t test whether the diet works as well when adapted for people in non-Mediterranean regions where these foods aren’t traditional. This study fills that gap by testing cultural adaptation. Previous research also relied heavily on in-person counseling, which isn’t accessible to everyone. This study’s use of video counseling and text messages represents an innovation in making dietary interventions more scalable and accessible.

This study hasn’t been completed yet, so we can’t evaluate all limitations. However, some potential limitations are worth noting: it’s a single-center study in Taiwan, so results may not apply equally to other countries or populations. The 12-week duration is relatively short for assessing long-term lifestyle changes and health improvements. The study doesn’t specify the exact number of participants yet, which affects statistical power. We won’t know if benefits persist after the intervention ends or how the intervention compares to other dietary approaches for fatty liver disease. Additionally, the study relies on participants’ ability to access video calls and text messaging, which may exclude some populations.

The Bottom Line

This is a study protocol, not completed research, so specific clinical recommendations aren’t yet available. However, the study design suggests that if you have fatty liver disease and live outside a Mediterranean region, a culturally adapted Mediterranean diet delivered through video counseling with a dietitian may be worth discussing with your doctor. The approach appears promising because it combines evidence-based nutrition (Mediterranean diet) with behavior change support (text messages) and personalized guidance (video counseling). Confidence in this recommendation will increase once the study is completed and results are published.

This research is most relevant to adults diagnosed with metabolic dysfunction-associated steatotic liver disease (fatty liver disease), particularly those in non-Mediterranean regions. It’s also relevant to healthcare providers, dietitians, and public health officials looking for scalable ways to treat fatty liver disease. People with metabolic syndrome, obesity, or type 2 diabetes should care about this research because these conditions increase fatty liver disease risk. However, this study protocol isn’t yet applicable to clinical practice—we need to wait for results before making treatment decisions.

The study itself runs for 12 weeks, with the primary measurement taken at week 12. However, the full study timeline (recruitment, completion, analysis, and publication) typically takes 1-2 years from the protocol publication date. Realistic expectations for seeing liver fat improvements, based on similar Mediterranean diet studies, range from 4-12 weeks, though individual results vary. Long-term benefits beyond 12 weeks remain unknown until follow-up studies are conducted.

Frequently Asked Questions

Can the Mediterranean diet help treat fatty liver disease?

Research shows the Mediterranean diet benefits liver health, but this new study tests whether it works when adapted for people outside Mediterranean regions. Results will be available once the 12-week trial completes, likely in 2025-2026.

How does video counseling with a dietitian help people stick to a diet?

Video counseling allows personalized feedback based on your actual food choices (shown through photos) and combines it with weekly text message reminders. This combination of personalized guidance and ongoing support helps address individual barriers to diet adherence.

What is metabolic dysfunction-associated steatotic liver disease?

It’s the medical term for fatty liver disease caused by metabolic problems like obesity, insulin resistance, or high cholesterol. Fat accumulates in liver cells and can cause inflammation, scarring, and eventually liver damage if untreated.

How long does it take to see improvements in fatty liver disease from diet changes?

Similar Mediterranean diet studies show liver fat improvements within 4-12 weeks, though individual results vary. This study measures changes at 12 weeks, but long-term benefits beyond that timeframe remain to be determined.

Is the Mediterranean diet practical for people who don’t live in Mediterranean countries?

This study specifically addresses that question by adapting the Mediterranean diet for non-Mediterranean regions. The dietitian personalizes recommendations based on available foods and cultural preferences, making it more practical and sustainable.
