This means that for every macronutrient there is a gram per calorie associated.

What are the Macronutrients that Don’t Provide Energy?

These are substances that contribute to the body in a different way. They don’t add energy or calories to be burned but are important to the body too as they perform a different function. Here are the macronutrients that don’t provide energy:

  • Water: this is the most essential and basic substance of all living things. This is very important as it plays an important role in the absorption of these nutrients. This is clear, tasteless, and odorless that can be found everywhere. Drinking water can soothe dryness and provide a great feeling for the body.

  • Antioxidants: this nutrient substance helps in preventing and delaying cell damages. It neutralizes free radicals, which are cell waste substances from the environment and food processed. They harm cells and body function. Antioxidant combats this free-radicals to achieve better good health.

What are the Macronutrients that Provide Energy?

These type of Macronutrients are the ones that produce and exude energy to the body. They are important because they are the fuel that energizes the activities of the muscles and brain. Here are the main macronutrient groups:


Carbohydrates are the nutrient that provides or is the main source of energy for the body. Called carbohydrates because of its chemical content of carbon, hydrogen, and oxygen. The process works as the carbs go in it then gets metabolized, broken down into glucose and use it as the body’s main fuel. As these are the sugars, starches, and digestible fiber sourced from fruits, grains, and vegetables.

To function properly the body needs carbohydrates. The brain, kidneys, muscles, and heart needs the energy coming from carbohydrates. It serves as the fuel to the central nervous system and makes the muscles function.

Samples of Carbohydrates

  • Rice: this is a great source of carbohydrates as rice turns into glucose and provide energy for the body.
  • Potato: potatoes are a good source for carbs, as they are starchy vegetables and has a high glycemic index (GI).
  • Corn: corn is another good source of carbs. It contains more carbohydrates than it’s counterpart vegetables like broccoli and Brussels sprouts.


Proteins are composed of many building blocks called amino acids. It helps the body grow, repair body tissues, and perform daily functions. Plus, it makes enzymes, hormones, and other body chemicals. This process starts with proteins broken into enzymes and turn into amino acids. These amino acids then pass through the gut and bloodstream to stimulate new proteins in the muscles. This repair and restore the damaged muscle fibers which allow it to sustain and expand. Protein can be found in foods like meats, seafood, eggs, nuts, and beans to name a few.

Samples of Protein

  • Meat: meat is the best food to get quality and high protein. From food sources like fish, chicken, and beef it offers essential amino acids that the body requires to build proteins.


Fats are an important food group that makes our body healthy. It adds to the weight gain of the body, has higher energy content, and insulate the body. Fats have many types from unsaturated, saturated, and trans fats to name some. It is a concentrated source of energy. It is high in calories that’s why it is used by some as their primary source of fuel in their diet. One gram of fat is double than the combined one gram of carbohydrate and protein.
