The gastric sleeve operation is a weight loss procedure that reduces the size of the stomach. In the weeks and months before the operation, patients are advised to follow a diet that restricts their calorie intake to around 1000 calories per day. This pre-op diet also involves reducing the consumption of carbohydrates and sugars, and increasing protein and healthy fat intake. The aim of this diet is to help patients lose weight before the operation and to reduce the risk of complications during surgery.

What You'll Learn
The small size of the stomach means a severe calorie restriction is required
The small size of the stomach after gastric sleeve surgery means a severe calorie restriction is required. Patients are advised to restrict themselves to about 1,000 calories per day during the first six months post-op. This is because the stomach is much smaller after surgery, so it can only hold a limited amount of food.
The pre-op diet for gastric sleeve surgery focuses on reducing calories, particularly from carbohydrates, and increasing protein and healthy fat intake. This is to ensure that the patient is in the best possible health before the operation. The diet usually begins about two to three weeks before the surgery and eliminates refined sugars, such as those in soft drinks and candies. Carbohydrates should be minimised, and patients should aim to include at least 65g of protein in their daily diet, choosing healthy fats such as those found in olives, nuts, and fish.
After the surgery, patients can consume a bit more at each meal, which will increase their calorie intake. However, it is important to be careful not to overdo it with calories during the first few months post-op. Most patients can expect to lose about 50% of their excess body weight within the first six months after surgery.

Carbohydrates should be minimised
During the first six months post-op, most patients will need to consume no more than 1000 calories per day. This is because the stomach is smaller after gastric sleeve surgery, and so it cannot hold as much food. This means that you will need to be careful not to overdo it with calories, as most patients can expect to lose about 50% of their excess body weight within the first six months after surgery.
The pre-op diet for gastric sleeve surgery typically begins about two to three weeks before the procedure. During this time, it is important to restrict your calorie intake to about 1000 calories per day. This means minimising the intake of carbohydrates and sugars, as well as increasing your protein intake to at least 65g per day.
It is also important to choose healthy fats, such as those found in olives, nuts, and fish, instead of unhealthy trans fats and saturated fats found in oil or butter. This is because the pre-op diet for gastric sleeve surgery is not just about reducing calories, but also about ensuring that you are getting the right balance of nutrients to support your health and recovery.

At least 65g of protein should be consumed daily
The gastric sleeve pre-op diet is aimed at reducing your daily calorie intake, as well as reducing the consumption of carbohydrates and sugars. This is because the stomach is smaller after surgery and requires a severe calorie restriction. During the first six months post-op, most patients will need to consume no more than 1000 calories per day.
The gastric sleeve pre-op diet also requires an increase in protein intake, with at least 65g of protein to be consumed daily. This is because protein is an important part of every diet, especially in increasing or maintaining muscle mass. In general, it is recommended that most adults get at least 10% to 35% of their daily calories from protein. The Food and Drug Administration suggests that most US adults require around 50 grams of protein daily, but this depends on your age, sex, health status, and activity levels. The ideal amount of protein you should consume each day is uncertain, with commonly quoted recommendations of 56 grams per day for men and 46 grams per day for women. However, more physically active people may also need more daily protein.
To get at least 65g of protein in your diet, you could consume a serving of low-fat Greek yogurt, a 4 oz serving of lean chicken breast, and a bowl of cereal with skim milk. You should spread your protein consumption across all of your meals throughout the day and choose a well-balanced diet that includes lots of vegetables, fruits, and fibre.

Healthy fats should be chosen over unhealthy trans fats and saturated fats
The pre-op diet for gastric sleeve surgery focuses on reducing calories, particularly from carbohydrates and sugars, and increasing protein and healthy fat intake. Patients are advised to restrict themselves to about 1,000 calories per day during the first six months post-op. This is due to the small size of the stomach and the severe calorie restriction that is required.
By choosing healthy fats, you can improve your overall health and well-being while still meeting your calorie goals. It is important to work with a healthcare professional to determine the right diet plan for your individual needs. They can provide guidance on which foods to choose and how to incorporate them into your diet in a healthy and sustainable way.
In addition to healthy fats, it is important to include a variety of other nutrient-dense foods in your diet. Lean proteins, such as chicken, turkey, and fish, can help to increase your protein intake while keeping calories relatively low. Complex carbohydrates, such as whole grains, legumes, and vegetables, can provide essential nutrients and fibre while still keeping your calorie intake within a healthy range.
By focusing on healthy fats and other nutrient-dense foods, you can ensure that you are getting the calories and nutrients your body needs while avoiding the negative health consequences of unhealthy fats. This approach can help you to achieve your weight loss goals and improve your overall health and well-being.

Refined sugars should be eliminated
A gastric sleeve operation reduces the size of the stomach, which means a severe calorie restriction is required. In the first six months after surgery, patients are advised to consume no more than 1000 calories per day.
The pre-op diet for a gastric sleeve operation focuses on reducing calories, particularly from carbohydrates, and eliminating refined sugars. Refined sugars should be eliminated because they are a source of empty calories, which means they provide energy but have little to no nutritional value. This can lead to weight gain and health issues such as tooth decay and type 2 diabetes.
In the weeks leading up to a gastric sleeve operation, patients are advised to reduce their daily calorie intake and minimise the consumption of carbohydrates and sugars. This is to help shrink the liver, which makes the surgery safer and easier to perform.
The post-op diet for a gastric sleeve operation also involves reducing calories and increasing protein and healthy fat intake. This is to aid in weight loss and ensure the body is getting the nutrients it needs to heal.
It is important to note that the advice provided here is general in nature and may not apply to everyone. It is always best to consult with a healthcare professional for personalised advice and guidance.
