How much protein after bariatric surgery?


After undergoing bariatric surgery, it is essential to follow a proper diet to aid in recovery and achieve long-term weight loss goals. One crucial aspect of post-bariatric surgery nutrition is the consumption of adequate protein. Protein plays a vital role in the healing process, muscle maintenance, and overall health. In this article, we will explore the importance of protein after bariatric surgery and discuss how much protein is recommended for individuals who have undergone this procedure.

The Importance of Protein after Bariatric Surgery

Protein is an essential macronutrient that is involved in various bodily functions. After bariatric surgery, the body requires an increased amount of protein to support the healing process and prevent muscle loss. Protein helps in tissue repair, wound healing, and the production of enzymes and hormones.

Moreover, protein has a higher thermic effect compared to carbohydrates and fats, meaning that it requires more energy to digest and metabolize. This can aid in weight loss and the maintenance of lean body mass, which is crucial for long-term success after bariatric surgery.

The recommended protein intake after bariatric surgery varies depending on the type of procedure performed and individual factors such as age, sex, and activity level. However, a general guideline is to consume around 60-80 grams of protein per day for most bariatric surgery patients.

It is important to note that this recommendation may change during different stages of the post-surgery diet. Immediately after surgery, the protein intake may be lower due to the limited capacity of the stomach. However, as the recovery progresses and the diet advances, protein intake should gradually increase.

Sources of Protein after Bariatric Surgery

Meeting the recommended protein intake after bariatric surgery can be challenging, especially considering the limited capacity of the stomach. Therefore, it is crucial to choose protein sources that are nutrient-dense and easily digestible.

Lean meats such as chicken, turkey, and fish are excellent sources of high-quality protein. Eggs, low-fat dairy products, and tofu are also good options. Additionally, protein supplements such as protein shakes or powders may be recommended to ensure adequate protein intake, especially during the early stages of the post-surgery diet when solid foods are limited.

Monitoring Protein Intake

It is essential to monitor protein intake after bariatric surgery to ensure that the recommended amount is being met. This can be done by keeping a food diary or using mobile applications that track macronutrient intake. Regular follow-up appointments with a registered dietitian or healthcare provider can also help in monitoring protein intake and making necessary adjustments.


Protein plays a crucial role in the recovery and long-term success of individuals who have undergone bariatric surgery. Adequate protein intake supports the healing process, helps maintain muscle mass, and aids in weight loss. The recommended protein intake after bariatric surgery is around 60-80 grams per day, although individual needs may vary. Choosing nutrient-dense protein sources and monitoring protein intake are essential for achieving optimal results.
