Is There a Need to Reassess Protein Intake Recommendations Following Metabolic Bariatric Surgery?

Abstract

Purpose of review: Protein intake is recognized as a key nutritional factor crucial for optimizing Metabolic Bariatric Surgery (MBS) outcomes by preventing protein malnutrition, preserving fat-free mass, and inducing satiety. This paper discusses the current evidence regarding protein intake and its impact on clinical outcomes following MBS.

Recent findings: There are considerable gaps in the understanding of protein requirements following MBS, as existing guidelines are based on limited and inconsistent reports. This highlights the urgent need for updated clinical practice recommendations grounded in high-quality evidence. Further investigation using robust methodologies is essential to address existing research gaps related to the individualization of protein requirements following MBS. Future research should consider factors such as the time elapsed since surgery, the form and quantity of protein consumed, and necessary adjustments for physical activity. Ultimately, in alignment with recent literature, a more specific and personalized dietary protein approach should be examined.
