Changes in Body Composition With Weight Loss Interventions
Summary
Host Dr. Bob Centaur interviews Dr. John Batsis about a systematic review on GLP-1 and lifestyle weight loss effects on body composition. They clarify that while muscle-related indices decrease, objective strength and performance data are lacking, suggesting lost mass may include intramuscular fat. Dr. Batsis emphasizes the scarcity of data in older adults and advocates for a team-based approach involving dietitians and resistance exercise to mitigate risks. The discussion concludes with a call to prioritize patient function and quality of life over weight-centric metrics.
