💥 Fuel Before & After Exercise, ItMatters More Than You Think!

A recent study of NCAA Division I cross country runners shows that even highly trained athletes often don’t meet carbohydrate or energy needs, especially around workouts.

Why it matters:
✅ Proper pre-run fueling = better performance
✅ Post-run recovery = faster muscle repair & glycogen replenishment
✅ Carbs = energy

What you eat before and after your practice impacts your training, recovery, and results. 🥗🍌💪

As you start the year, here’s your reminder that sports performance is about many factors, not just body weight.

There are many factors that matter, and these are a few that have the biggest impact 👇

⚡ Fuel timing & adequacy
Eating enough before, during, and after training supports energy, power, and recovery

🍞 Carbohydrate availability
Meeting carb requirements = better endurance, speed, and decision-making

💧 Hydration & electrolytes
Even mild dehydration can reduce strength, coordination, mental focus, and reaction time

😴 Sleep quality & consistency
Improves reaction time, mood, recovery, and injury resilience

🏋️ Strength & power development
Relative strength, rate of force development, and neuromuscular efficiency matter

🎯 Training quality & specificity
Smart programming > just doing more

🔁 Recovery practices
Rest days, deloads, mobility, and proper refueling drive adaptation

🧠 Mental strength
Confidence, focus, emotional regulation, and stress management impact performance

🧬 Hormonal health
Adequate energy supports hormones tied to strength, bone health, and recovery

🩸 Iron & micronutrient status
Key for oxygen delivery, fatigue management, overall health, and endurance

🩹 Injury prevention & availability
Refuel and fill in energy gaps with nutritious foods. Fuel to upcoming workouts rather than chasing hunger will keep bones and tissues healthy

🤝 Team environment & coaching
Psychological safety and trust improve effort and performance

➡️ Performance is multifactorial. Weight is only one small piece of the puzzle.

🎉Holiday routine
* Expect your schedule to shift. Be flexible. Do your best to get back to your normal routine as soon as you can.
* Keep a schedule. Aim to eat every 3–4 hours, even on rest days.
* Breakfast (within two hours of waking)
* Mid-morning snack
Lunch
* Afternoon snack
* Dinner
* Optional evening snack
* Fuel well on rest days: your body still needs three meals and a couple of snacks.
* Aim for balanced plates with carbohydrates, protein, and colorful fruits or vegetables.

🎉Sleep
* Maintain a consistent sleep routine. Try to go to bed at the same time each night.
* If falling asleep is tough: limit caffeine, charge your phone outside the bedroom, and decompress with something calming before bed.

🎉Stress & triggers
* Check in with your stress levels. Holidays can increase or decrease your appetite.
* Have a plan if being home is stressful:
* Stick to regular meal and snack times
* Keep snacks nearby so you don’t get overly hungry
* Take short breaks (walk, stretch, breathe) if things feel overwhelming

🎉Hydration
* Stay hydrated, especially when traveling or when routines change.
* Aim for 2–3 liters of fluids per day.
* Add electrolytes on training days or when flying.

✨ These small habits can make a big difference in keeping you fueled, grounded, and maintain training throughout the holiday season.

As a sports dietitian and runner, it’s hard to be sidelined by injury. Last year I developed a stress fracture while running a marathon (no, I didn’t finish the race).

Here are the strategies I focused on to help my body heal fast. ⬇️
✨ Focused on consistent fueling by eating before and after cross training and strength sessions.
✨Added more calcium + vitamin D–rich foods like yogurt, eggs, and cottage cheese.
✨Prioritized high quality protein at every meal for repair and expanded my food choices to include chicken, fish, turkey, eggs, and tofu.
✨Ate plenty of fruits + veggies for antioxidants like vitamins A, C, and E.
✨Rested when I needed it (even when it was hard!). That includes plenty of sleep. 💤
✨Worked closely with my physical therapist and coach Brendan (.run.academy )to return to running very slowly.

🍎I focused on being patient, consistent with fueling and trust the process.
