From the Guidelines
A diet for hepatic steatosis (fatty liver) should focus on reducing overall calorie intake and emphasizing whole, unprocessed foods, with the Mediterranean diet being particularly beneficial, as evidenced by the most recent study 1. The goal is to lose weight gradually if overweight, targeting 5-10% of body weight loss, which can significantly reduce liver fat. Key components of the diet include:
- Choosing complex carbohydrates with low glycemic index like whole grains, legumes, and vegetables
- Avoiding simple sugars and refined carbohydrates
- Including lean proteins such as fish, poultry, and plant-based options
- Limiting red and processed meats
- Healthy fats from sources like olive oil, avocados, and nuts are beneficial, but overall fat consumption, especially saturated and trans fats, should be reduced
- Avoiding alcohol completely as it directly damages liver cells and worsens fatty liver
- Staying well-hydrated with water and unsweetened beverages
- Considering coffee consumption (without added sugar or cream) as potentially protective for the liver
This dietary approach is supported by studies such as 1 and 1, which highlight the benefits of whole, unprocessed foods and the importance of omega-3 fatty acids in reducing hepatic steatosis. Additionally, guidelines from reputable organizations, such as those outlined in 1 and 1, recommend weight loss and lifestyle modification, including diet and exercise, as the primary approach to managing non-alcoholic fatty liver disease. The Mediterranean diet, in particular, has been shown to be beneficial for NAFLD, even when it is iso-caloric or there are no changes in body weight, as noted in 1. Regular physical activity of at least 150 minutes per week complements these dietary changes by improving metabolism and reducing liver fat independently of weight loss. By following this diet and lifestyle approach, individuals with hepatic steatosis can reduce inflammation, improve insulin sensitivity, and decrease fat accumulation in liver cells, allowing the liver to gradually heal and reduce fat content.
From the Research
Dietary Recommendations for Hepatic Steatosis
The recommended diet for hepatic steatosis (fatty liver disease) involves several key components:
- Weight loss for overweight patients, as increasing body mass index is a significant risk factor for developing non-alcoholic fatty liver disease (NAFLD) 2
- Short-term hypocaloric diets have shown beneficial effects in reducing intrahepatic lipid contents 2
- Macronutrient manipulations, such as:
- Dietary patterns, including:
- Mediterranean diet, which has been shown to significantly reduce hepatic steatosis and improve cardiometabolic risk factors 4
- Low-fat diet, which can also improve hepatic steatosis, although it may not be as effective as the Mediterranean diet in improving cardiometabolic risk factors 4
- Whole-grain consumption, which has been found to have beneficial effects on hepatic steatosis and liver enzymes in patients with NAFLD 5
- Limiting dietary fat intake, as high fat consumption can promote the development of hepatic steatosis independently of excess caloric consumption 6
Key Foods and Nutrients
Some key foods and nutrients that may be beneficial for hepatic steatosis include:
- Omega-3 fatty acids, which can be found in fatty fish, flaxseeds, and walnuts 3
- Whole grains, such as brown rice, quinoa, and whole-wheat bread 5
- Unsaturated fats, such as those found in avocados, nuts, and olive oil 2
- Foods low in saturated fats and added sugars, such as fruits, vegetables, and lean proteins 2, 6
Dietary Patterns to Avoid
Some dietary patterns that may exacerbate hepatic steatosis include:
