If your doctor has recommended a liver shrinking diet, it's likely in preparation for weight loss surgery or to address a condition like fatty liver disease. This article provides a detailed look at what a liver shrinking diet entails, why it's necessary, and offers sample recipes and menu ideas.
Understanding the Liver Shrinking Diet
A liver shrinking diet is characterized by its low calorie, low carbohydrate, and low fat content. The primary goal is to reduce the size of the liver before procedures like bariatric (weight loss) surgery. Your liver, constituting approximately 2% of your body weight, is the largest solid internal organ. Conditions that cause it to enlarge may necessitate dietary changes to prepare for surgery.
How It Works
The diet works by prompting the body to utilize its stored glycogen and lipids within the liver. As glycogen reserves deplete, water is also released, leading to a reduction in the liver's size and making it softer. This preparation is crucial for the dietary recommendations that follow weight loss surgery. Individuals diagnosed with fatty liver disease may already be familiar with similar dietary approaches.
Who Needs a Liver Shrinking Diet?
Typically, a doctor will recommend this diet to individuals preparing for weight loss surgery. The specific timeframe for starting the diet, which can range from 2 to 12 weeks before surgery, may depend on your body mass index (BMI) and the surgeon's preferences. One study indicated that the median time frame for initiating the diet was six weeks prior to surgery.
*If you are not asked by your surgeon, doctor, or nutritionist to lose weight before your surgery then you do not have to follow these plans, only the Pre-Op Clear Liquids Diet.

How Long Does It Take?
Restricting calories, carbohydrates, and fats can reduce liver size within a few weeks. Your doctor may also suggest nutritional supplements or an intragastric balloon prior to gastric bypass surgery. The average patient can expect to lose 6-8 pounds per month following these plans, so plan accordingly if you have a specific target you need to reach. Please note that results may vary and cannot be guaranteed.
Monitoring Your Progress
A liver shrinking diet limits carbohydrates and fats. Your doctor may recommend this type of diet before you undergo weight loss surgery. These meal plans are designed for patients that need to lose weight before having their gastric sleeve surgery.
Transitioning After Surgery
After your gastric sleeve, you’ll move through several dietary phases to ensure you receive the necessary nutrients. Initially, you’ll remain on clear liquids before transitioning to full liquids and, eventually, soft foods. Your surgeon will guide you through this transition to ensure proper healing and optimal results. Patients who follow the pre-op liquid diet and adhere to post-op guidelines often experience significant weight loss and improved overall health.
