Protein, Strength & Metabolic Goals Beyond Weight

Episode Summary

In this episode of In the Know with Nina, Dr. Nina Crowley is joined by Kim Tirapelle, MS, RD, CSSD—Bariatric Sports Dietitian and host of the Active Bariatric Nutrition Podcast. Together, they dive into how post-op bariatric patients and individuals on GLP-1s can preserve lean mass, fuel strength, and shift the focus from weight loss to body composition and performance.

They break down practical strategies for tailoring protein goals, integrating resistance training, and using body composition metrics to guide care. The conversation also explores when supplements like creatine make sense, and why segmental muscle analysis and visceral fat measures offer a more complete picture of metabolic health.
