You Can't Recover From Food You Didn't Eat

Training creates a demand for energy and nutrients. If you don't eat enough to cover training plus normal growth, your body cuts corners — and performance, bones, and hormones all suffer. Scientists call this low energy availability, and when it persists it becomes RED-S (Relative Energy Deficiency in Sport). It is common in track, and it is serious.

Why This Matters So Much for Teens

You're not just an athlete — you're still growing. Low energy availability during these years can weaken bones right when you should be building them for life, disrupt hormones, and drive bone-stress injuries (stress fractures). Estimates suggest RED-S affects a large share of athletes — by some reviews up to 23–80% of female and 15–70% of male athletes across sports. This is a health issue first, a performance issue second.

The Warning Signs (Take Them Seriously)

  • Always tired, getting sick often, frequent injuries — especially stress fractures
  • Performance stalling or declining despite training hard
  • In female athletes, missed or irregular periods — a major red flag, not a sign of "being in shape"

If any of these sound familiar, talk to a doctor or registered dietitian. Don't push through it.

The Basics of Fueling Well

  • Eat enough, consistently — three meals plus snacks, especially around training.
  • Carbs are fuel — they power hard sessions. Don't fear them.
  • Protein for repair — spread it across the day.
  • Refuel within ~30–60 minutes of hard sessions: carbs + protein + fluids.
  • Hydrate all day, not just at practice.

The Mindset

Food is part of training. The strongest, most durable athletes are usually the ones who fuel well — not the ones who restrict.

Eating enough isn't indulgent. It's how the work you put in actually sticks.
