Req 2c — Balanced Diet

Describe the elements of a nutritious, balanced diet, and explain what you do to maintain a healthy diet.

Food is fuel. Just like a car will not run well on the wrong type of gas, your body will not perform at its best without the right nutrients. A balanced diet gives you the energy to train, the building blocks to grow and repair muscle, and the vitamins and minerals to keep every system in your body running smoothly.

The Building Blocks of Nutrition

There are three macronutrients (nutrients your body needs in large amounts) and several key micronutrients (vitamins and minerals you need in smaller amounts). Together, they form the foundation of a healthy diet.

Carbohydrates — Your Primary Fuel

Carbohydrates are your body’s preferred energy source, especially during exercise. They break down into glucose, which your muscles burn during activity. Without enough carbs, you will feel tired, sluggish, and unable to maintain intensity.

Protein — Your Repair Crew

Protein is essential for building and repairing muscle tissue. After a hard workout, your muscles have small tears that protein helps repair — making you stronger for the next session.

Fats — Your Long-Lasting Energy Reserve

Fats sometimes get a bad reputation, but your body absolutely needs them. Healthy fats support brain function, protect your organs, help absorb vitamins, and provide a long-lasting energy source for lower-intensity activities.

The MyPlate Model

The USDA’s MyPlate is a simple visual guide to building a balanced meal. Imagine your plate divided into sections:

Micronutrients Athletes Should Know

While macronutrients get most of the attention, certain vitamins and minerals are especially important for active bodies:

Eating for Training

What you eat and when you eat it matters during a training program:

Before exercise (1–3 hours before): Eat a meal or snack rich in carbohydrates with some protein. Examples: a peanut butter sandwich, oatmeal with fruit, or a banana with yogurt.

During exercise (over 60 minutes): Sip water or a sports drink. For very long sessions, a small carb-rich snack like an energy bar or handful of raisins can help.

After exercise (within 30–60 minutes): Eat a combination of carbs and protein to replenish energy stores and kickstart muscle repair. Examples: chocolate milk (a classic recovery drink), a turkey wrap, or a smoothie with fruit and protein.

Maintaining Your Own Healthy Diet

The requirement asks you to explain what you do to eat well. Here are some practical strategies:
