This Incredibly Common Practice Could Be Hurting Your Athletic Performance

Elite athletes often reduce dietary intake to enhance performance, particularly in endurance sports. However, this can significantly impair performance and health, as shown by a 7.7% performance drop and increased stress markers in female athletes consuming only 50% of their energy needs for 14 days.

Whether they are preparing to compete in swimming, rowing, or running at the Olympics, or getting ready for the Tour de France, many elite athletes have focused on achieving an ‘ideal’ weight for decades. This may be to present a lean appearance in their swimsuit or jersey, or to meet specific weight class requirements. Additionally, there is a prevailing belief that weight loss can improve performance.
