Consuming extra calories can help exercising women avoid menstrual disorders

Washington, DC March 31, 2020

Exercising women who struggle to consume enough calories and have menstrual disorders can simply increase their food intake to recover their menstrual cycle, according to a study accepted for presentation at ENDO 2020, the Endocrine Society’s annual meeting, and publication in the Journal of the Endocrine Society. 

The study found that exercising women with menstrual disorders can start menstruating again by consuming an additional 300-400 calories a day.

“These findings can impact all exercising women, because many women strive to exercise for competitive and health-related reasons but may not be getting enough calories to support their exercise,” said lead researcher Mary Jane De Souza, Ph.D., of Penn State University.

By consuming enough calories, exercising women with menstrual disorders can avoid complications associated with a condition known as the Female Athlete Triad, De Souza said. This is a medical condition that starts with inadequate food intake that fails to meet the body’s needs. It leads to menstrual disorders and poor bone health. It is associated with a high incidence of stress fractures.

The study included 62 young, exercising women with infrequent menstrual periods. Thirty-two women increased their calorie intake an average of 300-400 calories a day, and 30 maintained their exercise and eating habits for the 12-month study. Women who consumed the extra calories were twice as likely to have their menstrual period during the study compared with the women who maintained their regular exercise and eating routine.

“This strategy is easy to implement with the help of a nutritionist. It does not require a prescription and avoids complications from drug therapy,” De Souza said. “The findings will encourage healthcare providers to try to help exercising women with menstrual disorders who consume too few calories to eat more, and this may help them to be healthier athletes and avoid bone complications.”

The Endocrine Society canceled its annual meeting, ENDO 2020, amid concerns about COVID-19. Visit our online newsroom for more information on accepted abstracts, which will be published in a special supplemental section of the Journal of the Endocrine Society.
