Coaches Guide to Nutrition: Underfueling
October 28, 2025
Athletes push their bodies to perform at high levels — and that requires consistent, adequate fueling.
Without enough calories to support training, recovery, daily life, and growth, performance and overall health can suffer.
In fact, underfueling — whether intentional or unintentional — can lead to a serious condition called Relative Energy Deficiency in Sport (REDs), which affects both male and female athletes.
Don’t let low energy hold you back! Fuel your body, protect your health, and train strong.

Coach's Guide to Nutrition: Pre-Workout Snacks
September 10, 2024
Heading into practice or a game under-fueled may take away from athlete performance. Encourage student-athletes to not only eat regularly throughout the day, but to have a small, carbohydrate-focused snack about 30-60 minutes before activity. This will top off their energy stores so they are ready to hit the field.
Pre-workout snacks don’t have to be complicated. Choose easy, high-carb snacks that can be stored safely in a gym bag.
Snacking can be detrimental when done out of boredom or in place of regular, balanced meals. But, for an athlete, healthy snacks can aid performance and recovery.
In planning to eat every 3-4 hours, a mid-morning snack may be ideal. Having a snack in the hour or two before practice and in the ‘window of opportunity’ following practice can help maintain energy levels and ensure proper recovery.
Work with your athletes to create simple snacks that are easy to transport. Encourage athletes to include a carb and protein in each snack when possible. Fresh fruit, granola bars with 8-10 grams of protein, or trail mix that includes nuts/seeds and dried fruit are easy to keep in a gym bag and relatively affordable. A small cooler with an ice pack is a great way to keep snacks cold and fresh.
Snacks are important to maintain energy between meals, before exercise and after workouts. Snacks before and after exercise help performance as well as aid optimal recovery. Try to include carbs and protein in every snack.
