                                According to the Academy of Nutrition and Dietetics, male teen athletes may need up to 4,000 calories per day, while female teen athletes may need up to 3,000 calories per day, depending on individual factors. For a 14-year-old swimmer, these figures are just a starting point for determining the significantly higher caloric requirements necessary to fuel intense training and rapid growth.
