Macronutrients

There are three different types of macronutrients, carbohydrates, proteins, and fats. Macronutrients are nutrients that you need a large amount of in your diet. Runners need macronutrients to sustain their energy throughout the race. Carbohydrates are the prime energy sources of the body. You need proteins because they are your body’s “workers.” For example, proteins help transport oxygen from the lungs to the rest of the body. Fats are important because they supply calories, energy, and help absorb vitamins for the body. As you can see, you need all three macronutrients in your diet plan in order to maintain a healthy lifestyle. For example, about 45-65% of your caloric intake should be carbohydrates, 20-35% should be fats, and 10-35% should be proteins.

Here are some samples of diets (Can you determine if they are good or bad?):
