Why Is Protein So Important After Sleeve Gastrectomy?

Last Updated on March 21, 2024

Optimizing Protein Intake After Sleeve Gastrectomy

Protein, a vital macronutrient comprised of amino acids, is essential for various bodily functions including cellular repair, growth, and immune defense. Post-sleeve gastrectomy, the significance of protein in the diet intensifies due to reduced stomach capacity—approximately 80% less.

Ensuring adequate protein intake becomes crucial for maintaining muscle mass and enhancing satiety on a significantly smaller food volume.

But how do you know how much you should be eating, and what the best sources are? That’s where we come in.

What is protein? 

Let’s start with the basics.

Protein is an essential macronutrient made up of many amino acids joined together, and is critical to many bodily functions. Protein helps to transport molecules throughout the body, repair cells and make new ones, protect the body from viruses and bacteria, and promote proper growth and development. 

When it comes to your post-sleeve-surgery diet, protein plays two very important roles. It helps to maintain muscle mass and prevent muscle loss during weight loss, and it increases satiety (the feeling of satisfaction after a meal) keeping you fuller, longer – with less food. 

How much protein do I need Post-operation? 

Post-operative protein requirements are influenced by factors such as age, gender, and physical activity levels. Typically, the target is between 60 to 80 grams of protein daily, distributed as 20-30 grams per meal and 5-15 grams per snack.

What should I eat? 

Initially, protein powders and shakes are pivotal in meeting protein needs due to the limited food volume post-surgery.

Opt for supplements high in protein but low in sugars and fats. Recommended products include Premier Protein®, Fairlife® 30g Protein, and protein isolates like Revolution Isolate Splash and Myprotein™️ Clear Whey Isolate.

As you transition to solid foods, prioritize high-quality protein sources such as chicken, beef, fish, eggs, dairy, and plant-based options like beans and lentils. Supplements can supplement dietary intake if necessary.

Integrating Technology and Apps for Monitoring Protein Intake

Mobile apps and wearable devices have revolutionized how individuals track their dietary intake, making it easier and more efficient to monitor crucial macronutrients, especially protein. For patients who have undergone sleeve gastrectomy, keeping a close eye on protein intake is essential due to their reduced stomach capacity and the vital role protein plays in recovery and weight management. Technological tools can assist in this process, providing real-time data, personalized insights, and progress tracking to ensure optimal nutritional intake.

Recommended Apps and Tools

To support patients in achieving their post-surgery protein goals, here is a curated list of mobile apps designed for comprehensive nutritional tracking:
