As a nutrition intern with UCLA Athletics, I spend my time helping support hundreds of Division I student-athletes. While most UCLA students aren’t training for national championships, many of the nutrition principles athletes follow can help anyone feel more energized, focused and prepared for busy days on campus.
1. Carbs are fuel
One of the biggest misconceptions I had before working in sports nutrition was that carbohydrates were something to avoid. In reality, carbohydrates are the body’s preferred source of energy.
Athletes rely on carbs to fuel practices, lifts, competitions and recovery. Even if you’re not competing, your brain uses glucose as its primary fuel source. Long days of classes, studying, walking across campus and exercising all require energy.
Carbohydrates aren’t the enemy — they’re what help you perform.
2. Recovery starts with sleep
Nutrition gets a lot of attention, but recovery isn’t just about food.
Sleep is one of the most powerful performance tools available. During sleep, the body repairs tissue, supports muscle recovery, regulates hormones and consolidates learning and memory.
You can have the perfect nutrition plan, but if you’re consistently sleeping four or five hours each night, you’re missing one of the biggest pieces of the puzzle.
3. Hydration impacts more than athletic performance
Most people only think about hydration when exercising, but dehydration can affect concentration, energy levels, mood and even headaches. For college students balancing classes, studying, workouts and long days on campus, staying hydrated can make a noticeable difference in how you feel throughout the day.
Hydration may also play a role in managing menstrual symptoms. While drinking more water won’t eliminate cramps, staying adequately hydrated can help reduce bloating and support overall comfort during your cycle. Combined with proper nutrition, sleep and movement, hydration is one of the simplest ways to support your body.
A simple habit like carrying a water bottle throughout the day can make a bigger difference than many people realize.
4. Fat is not something to fear
Another misconception is that dietary fat should be avoided.
Healthy fats play an important role in hormone production, nutrient absorption, brain function and long-lasting energy. Foods like avocados, nuts, seeds, olive oil and fatty fish provide nutrients that support overall health and performance.
Athletes don’t avoid fats — they learn how to incorporate them appropriately into a balanced diet.
5. Consistency beats perfection
Perhaps the biggest lesson I’ve learned is that nobody eats perfectly.
The athletes I see aren’t focused on having a “perfect” meal every time they eat. Instead, they focus on consistently making choices that support their goals over time.
For college students, that might mean eating breakfast more regularly, carrying snacks between classes, drinking more water or getting an extra hour of sleep.
Small habits repeated consistently often matter more than dramatic changes that only last one week.
