Teen Athletes Need Enough Food for Training and for Normal Development
- Puberty, menstrual development, bone growth, and school add to the load.
- Adolescent underfueling can change a health trajectory.

Nutrition for Adolescent Female Athletes
Teen female athletes are fueling both training and development at the same time.
Adolescent female athletes are not just smaller adults. Growth, puberty, school schedules, and training all hit the nutrition budget at once.
Bottom line
Teen female athletes need fuel for growth and sport at once.
You are growing and training at the same time
- Your body is building bones and growing taller right now.
- Growing takes food, and running takes food, so you need enough for both.
- Miss meals a lot and your body may cut back on growing to keep you moving.
Do this:
- Eat breakfast before first period, even cereal and milk.
- Put a snack in your backpack for the hour before practice.
- Add milk, yogurt, or cheese to one meal each day.
Try this week: Eat breakfast every school day this week and notice how practice feels on Friday.
Not true: eating less makes you a more serious athlete. Eating enough does.
Familiar products to recognize
Start with the food category. Tap a package for one recognizable brand example, then swap within the category for access, tolerance, culture, budget, and allergens.
Put it into practice
The Biggest Misses Usually Happen Between First Period and Practice
- Skipped breakfast, weak lunch, no afternoon snack: training on fumes.
- School and commuting schedules make portable fuel non-negotiable.
Calcium, Vitamin D, Iron, Protein, and Enough Total Energy Deserve Consistent Attention
- These nutrients interact with growth, bone, blood, and recovery.
- Teen girls who train hard need more planning than adults realize.
Do Not Coach Teen Girls as if Smaller Portions Are Automatically More Disciplined
- Restriction often looks tidy before it starts looking risky.
- Praise for tiny appetites or visible leanness moves behavior fast.

| Calcium | Bone is still being built | Milk, yogurt, cheese, fortified alternatives |
| Iron | Growth and menstrual losses | Red meat, beans, fortified cereal with vitamin C |

For the runner
You are growing and training at the same time
- Your body is building bones and growing taller right now.
- Growing takes food, and running takes food, so you need enough for both.
- Miss meals a lot and your body may cut back on growing to keep you moving.
- 1Eat breakfast before first period, even cereal and milk.
- 2Put a snack in your backpack for the hour before practice.
- 3Add milk, yogurt, or cheese to one meal each day.
Try this week: Eat breakfast every school day this week and notice how practice feels on Friday.
Not true: eating less makes you a more serious athlete. Eating enough does.
Coach: say this
- You are paying two bills right now, growing and training. Both get paid with food. Eating enough is part of being serious.
- First period to practice is most of your day. If breakfast and lunch were thin, the hard part of today already happened.
- Milk, yogurt, cheese, or a fortified drink once a day. Your bones are still being built and this is the window.
- I will never praise a small plate or a smaller body. If you hear that from anyone on this team, come tell me.
Why it works
Adolescence is when a large share of lifetime bone is laid down, and bone building runs on total energy, calcium, and the loading that running provides.
When intake repeatedly falls short of growth plus training, the body can respond by turning down growth, bone building, and the menstrual cycle.
Growth and menstrual losses raise iron needs, which is why the sheet keeps iron-rich food on the plate and leaves testing or pills to the physician.
Don't say
- “Wow, you eat like a bird and still run like that.” Praising a tiny appetite teaches the whole team that eating less is admirable.
- “Girls your age should watch what they eat.” It turns growth into a problem to manage and hands a teen a reason to restrict.
- “Get your iron checked before the meet.” Picking the test is the physician's call; describe what you see and hand it to the family.
Refer whenAn athlete who mentions her period stopped or changed, shin or foot pain that lingers, eating visibly less as mileage climbs, or times falling despite hard work: tell the family privately this week and route to the pediatrician or athletic trainer. Fainting or chest pain is an emergency call.
Ask themWhere do your breakfast, lunch, and pre-practice snack actually happen on a school day?
For families
Feed the growth bill and the training bill
- Bone is still being built, so something dairy or fortified goes in daily. Milk with cereal, string cheese in the backpack, or yogurt after practice.
- Iron comes from food first: beans, red meat, or fortified cereal, with fruit at the same meal. Anything in a bottle is the pediatrician's call.
- Meals go missing between first period and practice. Pack the snack in the backpack, not the locker, and ask about lunch without making it a fight.
- Skip comments about portions and bodies at the table. Praise for eating less can push a teen girl toward restriction fast.
Watch for · A period that stops or changes, shin or bone pain that keeps coming back, or eating less as training goes up is the signal. Call the pediatrician and let the coach know you are on it.
