Performance nutrition
How you fuel your body can make a meaningful difference in your energy, strength, focus and overall performance. Whether you’re heading into a workout, a busy workday or simply trying to feel your best. Performance nutrition is not just for athletes. It’s about giving your body the right balance of nutrients to support the demands of everyday life.
This guide outlines how carbohydrates, protein, fats, hydration and timing all work together to support stamina, recovery and long-term well-being.
As always, talk with your doctor or a registered dietitian if you have a health condition, take medication or have questions about what approach is best for you.
Why performance nutrition matters
Your body relies on fuel to do almost everything, from walking across campus to lifting groceries and managing long workdays. Eating in a way that supports performance can help:
- Improve energy levels throughout the day
- Support muscle strength and repair
- Enhance focus and productivity
- Reduce fatigue
- Support immune health
- Improve recovery after activity
Performance nutrition is simply about meeting your body’s needs at the right times.
Key nutrients for performance
Carbohydrates: Your primary energy source
Carbohydrates provide quick, efficient energy for movement and mental focus.
Sources: whole grains, fruits, starchy vegetables, beans, yogurt and oats
Why you need them:
- Provide fuel for muscles and the brain
- Support endurance and stamina
- Help prevent fatigue and “energy crashes”
Tip: Include a carbohydrate source at every meal.
Protein: Strength and recovery
Protein supports muscle repair, daily strength and satiety.
Sources: lean meats, fish, eggs, beans, tofu, tempeh, yogurt and lentils
Why you need it:
- Helps repair tissues after movement
- Supports muscle maintenance
- Keeps you full and energized
Goal: Aim to include a source of protein at every meal and snack.
Healthy fats: Long-lasting energy
Healthy fats help stabilize energy and support nutrient absorption.
Sources: nuts, seeds, avocado, olive oil and fatty fish
Why you need them:
- Provide slow-burning energy
- Reduce inflammation
- Support brain function
Micronutrients to support activity
- Iron: oxygen delivery (leafy greens, lentils, meats)
- Calcium & Vitamin D: bone health (dairy, fortified milks, leafy greens)
- Magnesium: muscle and nerve support (nuts, seeds, whole grains)
- Electrolytes: hydration balance (fruits, vegetables, coconut water, sports drinks when needed)
If you have deficiencies or a condition affecting nutrient absorption, talk to your doctor about testing or supplementation.
Fueling around movement
Before Activity (1–3 hours before)
Choose easy-to-digest foods with carbohydrates + a small amount of protein.
Examples:
- Banana + peanut butter
- Yogurt with fruit
- Whole-grain toast with eggs
- Oatmeal with berries
During activity (For longer or intense sessions)
Hydrate and, for activities over 60 minutes, add quick carbs.
Examples:
- Water or electrolyte drink
- Sports chews or fruit
- Diluted juice
Most people only need water unless exercising intensely or for long duration.
After activity (Within 1–2 hours)
Focus on protein + carbohydrates to support recovery.
Examples:
- Smoothie with yogurt, fruit, and spinach
- Rice bowl with chicken or tofu and vegetables
- Whole-grain wrap with beans and veggies
- Cottage cheese with fruit
Daily hydration for performance
Hydration is essential for energy, temperature regulation and muscle function. General guideline: aim for steady hydration throughout the day.
Increase fluids when:
- You’re active
- It’s hot or humid
- You consume caffeine
- You’re sick or dehydrated
Electrolytes matter if you sweat heavily or exercise for more than one hour.
Your doctor can help determine individual hydration needs if you take medications, have kidney concerns, or have heart conditions.
Sample performance-friendly day of eating
- Breakfast: Greek yogurt parfait with fruit, oats and nuts
- Snack: Banana and handful of almonds
- Lunch: Quinoa bowl with chicken or tofu, roasted vegetables and olive oil
- Snack: Cottage cheese, fruit or hummus with whole-grain crackers
- Dinner: Salmon or lentils with brown rice, greens and olive oil
- Hydration: Water throughout the day; electrolytes if needed
