Former collegiate runner Erin McDonald shares how “being careful” with food slowly became restriction. By choosing to fuel, not fear, she rebuilt her energy, joy, and speed—proving your fastest self isn’t your smallest, but the one that’s nourished, resilient, and free.
When “Healthy” Becomes Harmful
When people picture disordered eating in sport, they often imagine extremes — skipped meals, calorie counting, or visible restriction.
But for many athletes, the struggle is subtle. It lives in the small decisions: delaying meals, skipping recovery snacks, or “balancing” dessert with lighter dinners. These quiet habits often hide behind the language of discipline — until the body and mind begin to break down.
Erin McDonald, a professional distance runner for Peninsula Distance Club in the Bay Area, knows this gray area well. A former standout at Michigan State, she didn’t fit the stereotype of someone struggling with food. But over time, “just being careful” became quietly consuming.
“I never had the typical behaviors of someone with an eating disorder,” Erin explained. “But just because you don’t fit into a diagnosis doesn’t mean you’re in the clear.”
Her story isn’t about extremes. It’s about the small, invisible patterns that erode energy, motivation, and joy — and how letting go of control built her back stronger than ever.
At Strive to Thrive Coaching, we see this often: the habits that once seemed healthy can quietly turn harmful when they come from fear instead of self-trust.
Breaking Point to Breakthrough
Over time, Erin’s body began sending signals she could no longer ignore. “I’d either get injured, or my races would become more inconsistent,” she said. “I’d feel tired, sore, and anxious all the time.”
Eventually, she reached a breaking point — and it became her turning point. “I was so fed up with feeling tired, sore, hungry, and rigid that I stopped caring if weight gain would slow me down,” Erin said. “I just wanted to feel like myself again — and somehow, I ended up running faster than ever.”
That realization — that performance and well-being can coexist — flipped the script. “I thought it had to be either/or,” she reflected. “But it’s supposed to be both.”
Letting go of control didn’t make her weaker. It made her whole.
The Paradox of Feeling “Lighter”
When Erin began fueling properly and releasing guilt around food, she noticed an unexpected change. “Of course I meant it literally, feeling lighter during runs,” she said. “But I also meant it mentally — it was like a huge weight lifted. Restriction creates anxiety at every meal decision. It keeps you constantly thinking about food. When you can just let that go, it’s so freeing.”
That lightness wasn’t about pounds — it was about presence.
Coach’s Note: Food restriction doesn’t make you dedicated — it makes you depleted.
From a physiological standpoint, Erin’s experience mirrors what research shows: balanced fueling improves hormone regulation, stabilizes mood, and enhances recovery. In short — fueling is performance.
Subtle Signs We Miss
Erin’s story shows how easy it is to overlook quiet under-fueling — especially among athletes who seem strong and functional. “There’s no one-size-fits-all or clear ‘symptom,’” she said. “Everyone is so different.”
Common red flags can include:
- Frequent injuries or illnesses
- Persistent fatigue despite adequate sleep
- Heightened anxiety or emotional swings
- Obsession with “clean” eating
- Relying on liquids to suppress hunger
- Avoiding sugar, gels, or sports drinks during long training
Even “positive” behaviors — like balancing dessert with smaller meals — can be warning signs when rooted in guilt rather than balance. “Two runners can look pretty similar,” Erin said, “and one is fueling properly while the other isn’t. The difference might be only a few pounds, but that’s enough to be detrimental.”
Rethinking What Strength Looks Like
“I used to think I’d look so different if I gained weight,” Erin noted. “But the reality was just more muscle in my legs and glutes. Honestly, I look closer to a professional runner now than I did back then.”
Her words cut through a cultural illusion — that leanness equals speed. At Strive to Thrive Coaching, we teach that strength isn’t found in appearance, but in relationship: with one’s body, food, and mindset.
Pro Tip: Your fastest self isn’t your smallest self — it’s your strongest, most fueled self.
Coaching Insight: The Body Image Continuum
Through our work with athletes, teens, and young adults, we often see that body image isn’t static — it’s a continuum shaped by self-talk, comparison, and context.

Control & Comparison |
“If I look like them, I’ll perform like them.” |

Erin’s Message to Young Athletes
Looking back, Erin’s advice is as simple as it is profound: “Being smaller might make you faster in the short term — but it’s not sustainable. Fuel for the long term. Train harder, adapt, and you’ll end up faster than you ever thought possible — and you’ll actually enjoy it.”
Tools for Thriving: A Fuel & Mindset Reset
Building a healthier relationship with food and training starts with awareness. Use these reflection prompts to strengthen both your body and mindset:
- Listen to recovery cues: Fatigue or lingering soreness isn’t failure — it’s feedback.
- Refuel within 30 minutes post-workout: Pair carbs + protein to restore glycogen and rebuild muscle.
- Check your self-talk: Replace “I have to earn food” with “I get to fuel my body.”
- Practice flexibility: Can you enjoy dessert without “compensating”? Balance includes freedom.
- Notice mental fog: Irritability or lack of focus often signals low energy availability.
- Talk about it: Vulnerability creates connection and breaks shame.
- Celebrate strength over size: Focus on what your body can do, not how it appears.
- Stay curious: Learn about RED-S and fueling for performance — knowledge prevents burnout.
✏️ Coach’s Note: Progress isn’t measured by calories or scales — it’s measured by energy, confidence, and joy returning to your daily life.
From Restriction to Resilience
At its core, Erin’s journey is about trust — learning to listen instead of control, to nourish instead of restrict. The same truth applies far beyond sport. Whether you’re a student rebuilding confidence after therapy, a parent navigating recovery with your child, or an athlete rediscovering joy in movement — thriving starts with consistency and compassion.
Small shifts really do create long-term strength.
Conclusion: The Freedom of Enough
Freedom doesn’t come from control — it comes from enough: enough fuel, enough rest, enough self-respect. For Erin, thriving meant showing up with energy and joy, not perfection.
And for all of us, that’s the goal — not to be flawless, but to be free.
