Abstract: Dear Editor-in-Chief: The writing group for the ACSM Position Stand on the female athlete triad thanks Dr. Lamont for her letter concerning the dietary protein needs of the female athlete. We do think that suppression of reproductive function and bone protein synthesis in severely undernourished female athletes may reflect a protein deficiency as well as an energy deficiency, but we agree that scientifically credible methods for measuring protein requirements for health and performance are lacking. We also agree that correcting an energy deficiency with a mixed diet will probably correct whatever currently unknowable protein deficiency there may also be. Because of many of the issues raised by Dr. Lamont, we had not planned on including the protein recommendation in the document, but we were requested to do so in the final review process.
