Aria SavannahRunning is an incredibly rewarding activity, but it can be hard to sustain if you aren’t fueling your body properly. As a beginner runner, one of the most common mistakes is under-eating, which can lead to poor performance, fatigue, and even injuries. If you’re running but not eating enough, you may find yourself struggling with energy levels, recovery, and overall motivation. In this article, we’ll go over 7 beginner running training mistakes from under-eating that can hold you back, and how to correct them for better results.
Running requires a combination of endurance, strength, and mental toughness. However, one critical factor that is often overlooked is nutrition. Without the proper fuel, your body can’t perform at its best. Whether you’re running for fun, fitness, or training for a marathon, your body needs the right nutrients to power through those long runs and recover afterward. Let’s dive into some of the most common under-eating mistakes that beginners make.
Mistake 1: Skipping Pre-Run Meals
One of the biggest mistakes beginner runners make is skipping pre-run meals. Many runners believe that running on an empty stomach will help them burn fat faster, but this is a harmful misconception. Running on low fuel can leave you feeling weak, dizzy, or fatigued mid-run.
The Impact on Energy Levels
When you don’t fuel your body properly before a run, your glycogen stores are depleted, which can lead to low energy and early fatigue. A lack of proper nutrition before your run can negatively affect your performance, causing you to cut your workout short.
How to Fuel Before Your Run
It’s essential to eat a small meal or snack at least 30 minutes before your run. Opt for a combination of carbohydrates and protein. A banana with a scoop of peanut butter or some whole-grain toast with avocado can do the trick. Don’t forget to hydrate before your run as well!

Mistake 2: Not Refueling After a Run
Many beginner runners make the mistake of not eating after their run, thinking they can skip meals or “just eat later.” However, your body needs immediate nutrition after running to help repair muscles and replenish lost nutrients.
Why Post-Run Nutrition Matters
Post-run nutrition helps with muscle recovery and restores glycogen levels. Without proper refueling, your body may struggle to recover, leaving you sore and fatigued.
What to Eat After Your Run
Ideally, you want to consume both carbs and protein within 30 minutes of finishing your run. A smoothie with fruits and protein powder or a yogurt with granola are great post-run options.

Mistake 3: Focusing on Calories Instead of Nutrients
Another common mistake is focusing too much on calorie counting instead of the quality of food you’re eating. While calories are important, it’s also essential to prioritize nutrient-dense foods that provide vitamins, minerals, and other essential nutrients.
The Dangers of Calorie Counting
Strictly focusing on calories can lead to an imbalanced diet, which can affect your overall performance. For runners, eating nutrient-rich foods will not only support your energy levels but will also help with recovery and injury prevention.
The Importance of Balanced Meals
Try to eat a balanced meal consisting of lean proteins, complex carbs, and healthy fats. Think grilled chicken with quinoa and roasted veggies, or a hearty salad with avocado, chickpeas, and a variety of colorful vegetables.
Mistake 4: Ignoring Hydration
Hydration is often neglected in running training, but it plays a vital role in your performance. Dehydration can lead to fatigue, cramps, and even injury.
The Link Between Hydration and Performance
Your body needs water to regulate body temperature, prevent cramping, and maintain proper muscle function during exercise. When you’re dehydrated, your body can’t perform at its best.
How Much Water Do You Need?
A good rule of thumb is to drink water regularly throughout the day, not just when you’re thirsty. Aim for at least 8 cups of water a day, and more if you’re running for extended periods. For long runs, consider sports drinks or electrolyte-rich beverages.

Mistake 5: Not Adjusting Nutrition for Training Intensity
If you’re ramping up your training or preparing for a race, your nutritional needs will change. Many beginners continue to eat the same amount despite the increased intensity of their training.
How Your Nutritional Needs Vary with Training
When you increase your mileage or training intensity, your body requires more energy. This means you’ll need to adjust your calorie intake and nutrient profile.
Fueling for Long Runs vs. Short Runs
For long runs, focus on carbohydrates to keep your energy levels up, while short runs may require fewer carbs and more protein. Always listen to your body, and if you’re feeling drained, it’s time to increase your intake.
Mistake 6: Underestimating the Role of Healthy Fats
Healthy fats are often overlooked by beginner runners. While carbs and proteins are important, fats play a crucial role in supporting long-term energy and hormone production.
Why Healthy Fats Are Essential for Runners
Fats help to maintain energy levels during longer training sessions and keep your joints lubricated. They also contribute to overall health by supporting your immune system.
Good Sources of Healthy Fats for Runners
Incorporate foods like avocados, nuts, seeds, and olive oil into your meals. These fats provide a slow-burning source of energy, ideal for longer runs or endurance events.
Mistake 7: Avoiding Carbohydrates Completely
Some beginners fall into the trap of avoiding carbohydrates to lose weight or feel “lighter” while running. However, carbs are the primary source of energy for endurance activities like running.
The Importance of Carbs in Running
Carbs provide your muscles with glycogen, which is the fuel needed for running. Without enough carbohydrates, your body won’t have the energy it needs for performance or recovery.
Best Sources of Carbohydrates for Runners
Opt for complex carbs like brown rice, sweet potatoes, oats, and whole grains. These foods provide sustained energy and help you maintain stamina throughout your training sessions.
Conclusion: The Importance of a Balanced Approach to Nutrition
To optimize your running performance and recover properly, you need to take a balanced approach to your nutrition. This includes fueling before and after your runs, staying hydrated, eating nutrient-dense foods, and making adjustments based on your training intensity. Remember, nutrition is just as important as training when it comes to improving your running and reaching your fitness goals.
