For individuals with liver disease or those preparing for bariatric surgery, a liver reduction diet, also known as a liver shrinking diet, may be recommended. This specialized diet aims to support liver function, reduce its size, and minimize complications during surgical procedures. This article will explore the purpose, components, and implementation of a liver reduction diet, providing a comprehensive overview for those considering or embarking on this dietary approach.
Understanding the Liver and Its Role
The liver, the largest solid internal organ, constitutes approximately 2% of your body weight. It plays a vital role in various bodily functions, including:
- Bile Production: Facilitating the breakdown of fats in the small intestine during digestion.
- Cholesterol Synthesis: Producing cholesterol and specialized proteins for fat transportation throughout the body.
- Nutrient Processing: The liver also affects the absorption of food and the production of proteins and vitamins.
Why a Liver Reduction Diet?
Several conditions can lead to an enlarged liver, also known as hepatomegaly. In the context of bariatric surgery, an enlarged liver, often resulting from diets rich in sugars and starches, can pose challenges for surgeons. A liver that is too large may impede access to the stomach during surgery, increasing the risk of complications and potentially slowing down the healing process.
A liver reduction diet helps to decrease the amount of fat in your abdomen, both in and around your organs.
How the Diet Works
A liver shrinking diet works by prompting the body to utilize stored glycogen and lipids within the liver. As glycogen reserves are depleted, water is also released from the liver, contributing to a reduction in its size and making the organ softer. This approach aligns with dietary recommendations often prescribed following weight loss surgery, and it may also benefit individuals with fatty liver disease.

Dietary Changes for Liver Disease
Some people with liver disease must adhere to a special diet to aid liver function and prevent it from overworking. This diet often involves specific adjustments to macronutrient intake:
- Protein Management: Proteins are essential for tissue repair and preventing fatty buildup in the liver. However, in cases of severely damaged livers, proteins may not be processed efficiently, leading to a buildup of toxic waste products that can affect the brain. Dietary adjustments may involve reducing the intake of animal protein to limit the accumulation of these toxins.
- Carbohydrate Increase: Increasing carbohydrate intake to balance protein consumption is often recommended. Carbohydrates should be the major source of calories in this diet.
- Fat Intake: A moderate intake of fat, as prescribed by a healthcare provider, is often recommended. The increased carbohydrates and fat help prevent protein breakdown in the liver.
- Food Choices: Emphasizing fruits, vegetables, and lean protein sources like legumes, poultry, and fish is encouraged. Uncooked shellfish should be avoided due to the risk of hepatitis A.
- Vitamin and Mineral Supplementation: Liver disease can affect the absorption of food and the production of proteins and vitamins. Supplementation with vitamins and medicines prescribed by a healthcare provider may be necessary to address deficiencies, such as low blood count, nerve problems, or nutritional imbalances. Many people with liver disease are deficient in vitamin D, so vitamin D supplements may be recommended.
- Sodium Restriction: Limiting salt intake is crucial, as salt can exacerbate fluid buildup and swelling in the liver. Limit the amount of sodium you eat to 2000 milligrams per day or less to reduce fluid retention.
- Protein Needs: Have about 1.2 to 1.5 grams of protein per kilogram of body weight. Look for non-meat protein sources such as beans, tofu, and dairy products when you can.
General Recommendations for Severe Liver Disease
General recommendations for people with severe liver disease include:
- Carbohydrate Focus: Eat large amounts of carbohydrate foods.
- Moderate Fat Intake: Eat a moderate intake of fat, as prescribed by the provider.
- Protein Intake: Have about 1.2 to 1.5 grams of protein per kilogram of body weight. This means that a 154-pound (70-kilogram) man should eat 84 to 105 grams of protein per day. Look for non-meat protein sources such as beans, tofu, and dairy products when you can.
- Vitamin Supplements: Take vitamin supplements, especially B-complex vitamins.
- Sodium Limitation: Limit the amount of sodium you eat to 2000 milligrams per day or less to reduce fluid retention.
Foods to Include and Avoid
The liver reduction diet typically involves restricting calories, carbohydrates, and fats. Specific food recommendations include:
Foods to Include:
- Lean proteins: beef, pork, eggs, seafood or chicken
- Non-starchy vegetables: broccoli, cauliflower, leafy green vegetables
- Greek yogurt
Foods to Avoid:
- Fruit (limited due to high carbohydrate and sugar content)
- Alcohol
- Carbonated beverages
- Sugar
Sample Diet Menus
Here are a couple of sample liver shrinking diet menu ideas, but your doctor’s recommendations may vary.
Option 1:
- Four 325 milliliters (mL) (approximately 11 ounces) premade Slimfast protein meal replacement shakes
- Two servings of non-starchy vegetables a day
Option 2:
- Breakfast: 1 carbohydrate and 1 dairy portion
- Lunch: 2 protein and 2 vegetable portions
- Snack: 2 fruit portions as a snack during the day
- Evening Meal: 1 protein, 1 vegetable, 1 dairy, and 2 carbohydrate portions
Sample Daily Menu (Option 2):
- Breakfast: 1 piece of bread with 30 grams of light cream cheese
- Lunch: A cereal bowl of salad greens and 6 to 8 cherry tomatoes without dressing; 3 to 4 ounces of grilled chicken
- Snack (morning and/or afternoon): ½ banana, 1 cup of berries (or 2 servings of fruit per day, you can eat them at any time during the day)
- Dinner: 1 cup cooked broccoli with 1 teaspoon olive oil; a filet of salmon; a glass of skim milk; 4 tablespoons brown rice
In addition to the foods listed above, doctors may recommend at least 64 ounces of water or other approved fluids daily.

Duration of the Diet
The duration of a liver shrinking diet before surgery varies depending on individual factors, including body mass index (BMI). In one study, the median duration was six weeks before surgery, with a range of 2 to 12 weeks. Your doctor will determine the appropriate timeframe based on your specific needs.
Outcomes and Considerations
A study of 1699 adult patients across 14 bariatric centers in the United Kingdom found that 30.6% of patients achieved 5% weight loss during the LRD. The study also indicated that women had reduced odds of achieving this weight loss, while increasing age and having type 2 diabetes increased the odds.
Working with a Healthcare Team
It's essential to consult with a healthcare provider or registered dietitian to develop an individualized liver reduction diet plan. This ensures that the diet meets your specific nutritional needs and aligns with your overall health goals. A dietician can help you with your diet plan, answer your questions and help you after the surgery.
Additional Tips
- Hydrate: Drink at least 64 ounces (about 8 cups) a day of sugar-free, calorie-free, noncarbonated liquid per day.
- Avoid sugar, alcohol, carbonated beverages.
- Eat well: That means lots of protein, non-starchy vegetables and healthy fats.
Monitoring Progress
Restricting the amount of calories, carbohydrates, and fats in your diet can reduce your liver size within a few weeks. Your doctor may also suggest nutritional supplements or an intragastric balloon prior to a gastric bypass surgery.
A liver shrinking diet limits carbohydrates and fats. Your doctor may recommend this type of diet before you undergo weight loss surgery.
