You can't out-train a bad diet. Games are won in the fourth quarter when your legs are gone and your decisions get slow. Nutrition and recovery are what get you there fresh.
Pre-Game: 2–3 Hours Before Tip-Off
Carb-forward meal with moderate protein. Think: pasta with lean meat, rice bowls, oatmeal with banana. Avoid high fiber (GI distress mid-game) and heavy fat (slows digestion). 60–70% of your calories from carbs — your muscles are a tank, and you need to fill it.
During the Game
Water. If you're going more than 90 minutes, a sports drink with electrolytes helps. Keep it simple. Most youth and amateur players don't need anything more than water.
Post-Game Recovery Window (Within 60 Minutes)
Carb + protein within an hour of playing. Chocolate milk works. A real meal works better. Aim for 20–30g of protein and 60–80g of carbs for a 150–200lb player. This is when your body is most efficient at refueling.
The Basics: Water and Sleep
Most players are chronically dehydrated and sleep-deprived. 1 gallon of water per day. 8–9 hours of sleep per night. These two things alone will improve your performance more than any supplement or special diet.
Supplements That Move the Needle
Whey protein — if you can't get enough from food. Creatine monohydrate — one of the most studied supplements in sports science, improves power output. Caffeine — 200mg before a game improves decision speed and reaction time.
Everything else? Marketing. Stick to the basics: eat well, sleep well, train hard, get reps.
