What & Why

Meet Your Body's Fuel Crew!Just like a car needs gasoline, your body needs fuel from food to move, think, and grow. The three main types of fuel are called macronutrients. Let's meet them!1. Carbohydrates (Carbs) — The Go-GetterWhat they are: Sugars, starches, and fiber found in foods like bread, pasta, fruits, and vegetables.Their Job: Carbs are your body's #1 choice for quick energy. They are perfect for fueling up before a game or practice.2.

Example 1 — Pre-Game Power-Up

It's one hour before your big basketball game. You need energy that will kick in fast but won't make you feel sick or sluggish on the court.Your Goal: Choose a snack that is high in easily digestible carbohydrates.Smart Move: A banana, a handful of pretzels, or an apple. These are simple carbs that your body can quickly turn into fuel for the game.Tough Move: A big, greasy slice of pizza. The high fat and protein will take a long time to digest, which could make you feel slow and heavy.The Takeaway: Before activity, focus on carbs for quick, accessible energy!

Example 2 — Post-Workout Repair

You just finished a tough, sweaty soccer practice. Your muscles feel tired and a little sore. Now is the time to help them recover and get stronger for next time.Your Goal: Eat a snack with both protein and carbohydrates within an hour of finishing your workout.Smart Move: A glass of chocolate milk or a Greek yogurt with some berries. This combo gives you protein to start repairing your muscles and carbs to refill your energy tanks.Tough Move: A bag of gummy candies. This is all sugar (carbs) and has no protein to help your muscles. You'll get a quick sugar rush, but it won't help you recover properly.The Takeaway: After activity, pair protein with carbs to rebuild and refuel.
