American College of Sports Medicine position stand. Weight loss in wrestlers

Despite a growing body of evidence admonishing the behavior, weight cutting (rapid weight reduction) remains prevalent among wrestlers. Weight cutting has significant adverse consequences that may affect competitive performance, physical health, and normal growth and development. To enhance the education experience and reduce the health risks for the participants, the ACSM recommends measures to educate coaches and wrestlers toward sound nutrition and weight control behaviors, to curtail "weight cutting," and to enact rules that limit weight loss.
