Calorie Infographic Section: What are Calories?

Calories (or kilocalories) are the measurement of the energy that our bodies use for fuel. They power all of our bodies processes from sleeping to running.

Our bodies burn calories constantly so we constantly need to replenish them to live and function. You do this by consuming food and beverages throughout the day.

“Our brains, our muscles — every cell in our body — require energy to function in its optimal state,” said Jennifer McDaniel, a registered nutritionist dietitian in Clayton, Missouri, and spokesperson for the Academy of Nutrition and Dietetics. “So for one, we want to nourish our body right and our brain right. If we don’t get enough of those nutrients [that calories provide], there are negative consequences, whether its losing lean muscle mass, not being able to concentrate or not having the energy we need on a day-to-day basis.”

The amount of calories in food tells us the amount of energy that food will provide our body. They come from macronutrients: carbohydrates, proteins, and fats.

You can find the nutritional information on most food labels. This will tell you how many calories the food contains as well as the macronutrient breakdown.

Calorie Infographic Section: Macronutrients

Macronutrients are the nutrients that you use in the largest amounts. They are essential to your body processes.


There are 4 calories per gram of carbohydrate consumed. Carbs are the main source of fuel for the body and they are readily used for energy. They are important for central nervous system, kidney, muscle, and intestinal health. Good sources of carbs are grains, fruits, milk, and yogurt.


Like carbs, there are 4 calories per gram of protein consumed. Protein is used for growth, tissue repair, immune function, preserving lean muscle, and producing hormones and enzymes.

When carbs are not available, protein will also be used as an energy source for the body. Good sources of protein are animal products, nuts, and legumes.

As the highest energy source macronutrient, fats contain 9 calories per gram. Fats are used for cell, nerve tissue, and hormone production as well as the absorption of fat soluble vitamins. They are the most concentrated form of energy. Good sources of healthy fats are olive oil, nuts, and fatty fish like salmon.


This is not mentioned on the calories infographic but it does provide calories. Alcohol contains 7 calories per gram consumed.

The reason it was not included is that from a nutritional standpoint, it offers no nutritional value, or at least very little.

In 2013 I attended TVCC with my studies focusing on nutrition and biology. After leaving TVCC I pursued a career in inbound marketing and have worked in many different industries including health and fitness, firearms, coaching, and many more. I spent 6 years training for powerlifting and 6 years after training for a bodybuilding show in Idaho, which sadly did not come to fruition.
