What is the liver reduction diet?

A liver reduction diet (LRD) is a low-energy, low-carb, low-fat diet that reduces liver size for keyhole surgeries such as bariatric surgery. We advise you to stick to a maximum of 850kcal per day.

You will be asked to follow a liver reduction diet (LRD) before your bariatric surgery, such as the gastric sleeve, to reduce the size of your liver to make it easier for your surgeon to perform the keyhole surgery. We advise you to have a maximum of 850kcal per day along with a maximum of 80g of carbohydrates. This will force your body to use up glycogen stores in the liver, along with a quantity of water. These stored resources leave your liver, causing it to become softer, more flexible and easier to move during surgery. We advise you to start taking the recommended vitamin and mineral supplements when you start the liver reduction diet to reduce the risk of early deficiencies.

How long is a liver reduction diet?

It can vary depending on your BMI and typically we expect you to follow the below:
• If your BMI is 30-32 follow the diet for 3 days (850kcal per day)
• If your BMI is 32-35 follow the diet for 5 days (850kcal per day)
• If your BMI is 35-40 follow the diet for 1 week (850kcal per day)
• If your BMI is 40-50 follow the diet for 2 weeks (850kcal per day)
• If your BMI is 50-60 follow the diet for 3 weeks (week 1 1000kcal per day; weeks 2 & 3 850kcal per day)
• If your BMI>60 follow the diet for 4 weeks (weeks 1 & 2 1000kcal per day; weeks 3 & 4 850kcal per day)

What is the diet?

You need to follow a strict calorie intake of a maximum of 850kcal and 80g carbohydrates per day. If you have been advised to do this diet for longer than 2 weeks, it is normally suggested to start with 1000kcal per day before reducing to 850kcal per day for the last 2 weeks. For example:

You can see below a number of breakfast, lunch and dinner options that will keep you within the calorie limit and provide a healthy nutritional balance. You can of course have alternatives if they fit within the calorie and carbohydrate allowance. You can also follow a liquid liver reduction diet with having meal replacement shakes. The diet should be supplemented with water and/or low-calorie free drinks to ensure you are getting at least 2L of fluid per day. Tea and coffee can be taken with small amounts of milk only – no sugar.
