Under-Fueling Hides in Plain Sight
- Fatigue, irritability, flat workouts, and repeated illness are clues.
- Saying 'just not hungry' may be true; appetite can disconnect.
Aspire Parent Resources
My Runner Won't Eat
Most under-fueled high school runners are not being defiant. They are busy, disconnected from appetite, or quietly overwhelmed by food.
Parents help most when they reduce friction, speak calmly, and recognize when ordinary under-fueling is tipping into something more serious.
Bottom line
The goal is to make adequate eating easier, calmer, and safer before the problem deepens.
Not feeling hungry does not mean you are fueled
- After a long day and a hard run, hunger can switch off for a while.
- Your body still used that fuel. It needs it back, hungry or not.
- Feeling tired, cranky, or sick a lot can be your body asking for food.
Do this:
- Eat something small after practice, even when you are not hungry.
- Tell your family which foods are easy for you right now.
- If food feels scary or stressful, say so to an adult.
Try this week: Keep a car snack in your bag and eat it on the ride home, three days in a row.
Not true: not hungry means not needed. Your body used the fuel and wants it back.
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
Make Eating Easier First
- Visible snacks and ready meals beat repeated reminders.
- Busy athletes often miss food from disorganization, not from not caring.
Lead with Care, Not Control
- Use what you are noticing: low energy, slow recovery, frequent headaches.
- Avoid body comments or accusations about weight.
Know When It Is Time to Refer
- Less intake, fear foods, skipped meals, or withdrawal raise concern.
- Recurring illness, injury, fainting, or decline needs prompt help.

For the runner
Not feeling hungry does not mean you are fueled
- After a long day and a hard run, hunger can switch off for a while.
- Your body still used that fuel. It needs it back, hungry or not.
- Feeling tired, cranky, or sick a lot can be your body asking for food.
- 1Eat something small after practice, even when you are not hungry.
- 2Tell your family which foods are easy for you right now.
- 3If food feels scary or stressful, say so to an adult.
Try this week: Keep a car snack in your bag and eat it on the ride home, three days in a row.
Not true: not hungry means not needed. Your body used the fuel and wants it back.
Coach: say this
- If you are never hungry after practice, that is common and it is not a character flaw. Eat something small anyway; appetite usually catches up.
- Privately: I have noticed you seem wiped out after practice lately. I want to make sure you have enough fuel to feel good out there.
- To a parent, privately: Here is what I am seeing. Flat workouts and low energy for three weeks. I am not diagnosing anything.
- Nobody on this team gets asked what they weigh or told to eat more in front of others. That conversation is private, always.
Why it works
Hard training and a long day blunt appetite after practice, so 'just not hungry' is often true; the energy debt is real anyway and surfaces as fatigue and flat sessions.
Lowering friction works because many missed meals come from disorganization; food that is visible and ready gets eaten, while reminders add pressure and get tuned out.
Observation language keeps the athlete talking; body comments and accusations can push a teenager toward hiding food, which is the pattern that turns a logistics problem into a referral.
Don't say
- “You need to eat more.” Vague pressure with no food attached; it lands as criticism and teaches the athlete to hide.
- “You are getting too thin.” A body comment, even a worried one, makes the body the subject instead of the fuel.
- “I think you have an eating disorder.” Guessing a cause is a diagnosis; describe what you see and hand it to the family.
Refer whenIntake shrinking across weeks, fear foods or new food rules, eating alone, withdrawal from the team, recurring illness or injury, or fainting: tell the family privately this week and route to the pediatrician or athletic trainer. Collapse, chest pain, or confusion is an emergency call, not a conversation.
Ask themWhat is the easiest food for you to get down on a day you are not hungry?
For families
Pattern, not panic: make eating easier first
- Usually it is logistics: a busy day, no food in reach, appetite switched off after practice. Visible snacks and ready meals beat reminders.
- Put a car snack in the bag and something ready in the fridge door: chocolate milk, a smoothie, a sandwich half. Ready beats reminded.
- Open with what you notice, never the body: 'You seem wiped out after practice lately. I want you to have enough fuel to feel good.'
- Skip 'you need to eat more' and 'you're getting too thin.' Both tend to push a struggling teen toward hiding food rather than talking.
Watch for · Skipped meals on purpose, new food rules or fear foods, eating alone, fatigue sleep does not lift, or recurring illness, injury, or fainting: call the pediatrician and tell the coach. You do not need proof to ask.

When to use this
When a parent says their runner is not eating enough — the calm first response before anyone labels the problem.
- A busy athlete missing meals from disorganization rather than intent.
- Fatigue, irritability, or flat workouts showing up alongside shrinking intake.
- Deciding whether this is a logistics fix or the start of a referral conversation. Use the referral chain inside a school for who to tell, and in what order.

Conversation language and escalation paths
The sheet covers the pattern and the friction fixes. The exact words — and the line where this stops being a logistics problem — are here.
- Openers that work
- I've noticed you seem wiped out after practice lately, and I want to make sure you have enough fuel to feel good out there.' Observation plus care, with no mention of weight, portions, or willpower.
- Language to avoid
- You need to eat more,' 'you're getting too thin,' and any comment about the body — these reliably push a struggling teen toward hiding rather than talking.
- Warning signs that change the plan
- Fear foods, eating alone, new food rules, deliberate restriction, fainting, recurring injury, or worsening health changes mean the friction fixes are no longer enough — the next step is professional support.
- Escalation path
- Start with the pediatrician and ask about a referral to a sports dietitian experienced with adolescent athletes. If food fear or body distress is visible, ask about eating-disorder-informed support at the same visit — early is easier than certain.
This sheet is for noticing and starting the conversation, not for managing an eating disorder at home. If restriction, distress, fainting, or worsening health changes are present, involve the athlete's physician and an eating-disorder-informed sports dietitian promptly.
