Young athletes face unique challenges when it comes to nutrition. Proper fueling is not just about eating healthy foods; it is a strategic process that directly impacts strength, recovery, and overall performance. Misfueling can limit progress, cause fatigue, and increase injury risk. This guide provides clear, evidence-based direction to help you optimize nutrition for young athletes, ensuring they stay strong, recover well, and perform at their best.
Understanding Nutrition for Young Athletes
Nutrition for young athletes is a foundational element that supports training adaptations, energy levels, and injury prevention. Unlike adults, young athletes are still growing, which means their nutritional needs are more complex. You must balance energy intake to support both growth and athletic demands without creating deficits that impair performance or recovery.
Key components include:
Adequate calorie intake: Young athletes require enough calories to fuel daily activities, training, and growth. They usually need a minimum of 2200-2500 calories a day. Many need up to 3000-5000 calories a day and sometimes more!
Macronutrient balance: Complex and fruit Carbohydrates, lean proteins, and healthy fats each play distinct roles in energy provision, muscle repair, and hormone regulation.
Micronutrients: Vitamins and minerals support immune function, bone health, and energy metabolism.
Failing to meet these needs can lead to fatigue, stalled progress, and increased injury risk. For example, insufficient carbohydrates reduce glycogen stores, limiting endurance and strength during training. Inadequate protein intake slows muscle repair and growth, while poor hydration impairs cognitive function and increases cramping risk.
Key Macronutrients and Their Roles
Carbohydrates: The Primary Fuel Source
Carbohydrates are the main energy source during moderate to high-intensity exercise. They replenish glycogen stores in muscles and the liver, which are critical for sustained performance. Young athletes should consume complex carbohydrates such as whole grains, fruits, and vegetables to provide steady energy release.
Practical recommendations:
Include carbohydrates in every meal and snack.
Prioritize whole food sources like brown rice, oats, sweet potatoes, and fresh fruit.
Adjust intake based on training intensity and duration; longer or more intense sessions require more carbs.
Protein: Building and Repairing Muscle
Protein supports muscle repair, growth, and immune function. Young athletes need sufficient protein to recover from training and support growth. Sources include lean meats, dairy, eggs, legumes, and plant-based proteins.
Practical recommendations:
Aim for 14-28g of protein 4-6x a day. For personalized results seek out a Performance Fueling Dietitian/Advisor.
Distribute protein intake evenly across meals to maximize muscle protein synthesis.
Include a protein-rich along with carb snack after training to enhance recovery.
Fats: Essential for Hormones and Energy
Fats are vital for hormone production, brain development, and long-duration energy. Focus on healthy fats such as avocados, nuts, seeds, and olive oil. Avoid excessive saturated and trans fats.
Practical recommendations:
Include sources of omega-3 fatty acids (e.g., flaxseeds, walnuts, fatty fish) to reduce inflammation.
Balance fat intake to support energy needs without displacing carbohydrates and protein.
Hydration and Electrolyte Balance
Hydration is often overlooked but is critical for performance and recovery. Dehydration reduces strength, endurance, and cognitive function. Young athletes are particularly vulnerable to heat-related issues due to their developing thermoregulation systems.
Hydration strategies:
Encourage regular water intake throughout the day, not just during exercise. Usually 16-32oz of fluid every 3-4 hours and 3-4g of sodium from food, salt and product spread out evenly as well. (500-1000mg/sodium)
Use electrolyte-containing drinks during prolonged or intense activity, especially in hot conditions.
Monitor urine color as a simple hydration indicator; pale yellow is ideal.
Timing and Meal Planning for Optimal Performance
When young athletes eat is as important as what they eat. Proper timing ensures energy availability during training and supports recovery afterward.
Pre-Training Nutrition
Consume a balanced meal 2-4 hours before exercise.
Examples:
Turkey Sandwich with pb pretzels, carrots and an orange
Whole grain toast with peanut butter and banana, Soy milk
Oatmeal with berries, seeds and high protein yogurt
During Training
Stay hydrated
Aim for 4-16oz fluid an hour along with 0-500mg sodium
Carbs
Sometimes need carbs if a hard and long workout, didn't get to eat much prior, competition and longer than 90-120 minutes.
Consume 15-30g of carbohydrates per hour if needed
Use easily digestible sources like sports drinks, fruit, saltines, oyster crackers, pretzels, rice Chex, reg Cheerios
Post-Training Recovery
Aim to eat within 30-60 minutes after exercise.
Include 30-60g carbohydrates to replenish glycogen (carbs) and 10-28g protein to repair muscle. MUST HAVE TOGETHER.
Examples: chocolate milk, turkey sandwich, or a smoothie with fruit and protein powder.
Addressing Common Misfueling Patterns
Misfueling is a leading cause of performance breakdown in young athletes. Common patterns include:
Skipping meals or snacks, leading to low energy and poor recovery.
Inadequate carbohydrate intake, causing early fatigue and strength plateaus.
Insufficient protein, resulting in delayed muscle repair and increased soreness.
Poor hydration habits, increasing risk of cramps and heat-related fatigue.
To fix these issues, implement a structured fueling plan that matches training demands and individual needs. Educate athletes on the importance of consistent eating and hydration habits. Avoid blaming athletes for poor performance; instead, focus on system-level solutions that remove confusion and build confidence.

Supporting Long-Term Health and Performance
Nutrition is not just about immediate performance; it lays the foundation for long-term health and athletic development. Encourage habits that promote:
Balanced meals with variety and nutrient density.
Avoidance of restrictive diets or trends that can impair growth.
Regular monitoring of energy levels, recovery, and overall well-being.
By prioritizing nutrition as a system, you help young athletes avoid common pitfalls such as burnout, injury, and stalled progress. This approach builds resilience and supports sustained success.
Proper nutrition is a strategic tool that empowers young athletes to reach their potential. By addressing fueling mismatches and implementing evidence-based practices, you ensure they stay healthy, recover effectively, and perform when it matters most.
