Something Strange Is Happening to Athletes Who Take GLP-1s. Experts Are Racing to Find Out Why.

Athletes who have been taking GLP-1s for weight loss are reporting unusual changes in their heart rate, heart rate variability, and VO2 max, which are critical markers of cardiovascular health and athletic performance. This unexpected side effect has prompted experts to investigate the underlying causes, as it could impact not just the athletes but also the broader understanding of how these drugs affect the body. The implications are significant, especially since GLP-1s are increasingly prescribed for weight management, raising concerns about their long-term effects on physical fitness and health.
