Macronutrients – Carbohydrates, Proteins, Fats, Fibers, and Water

The three most popular macronutrients are carbohydrates, proteins, and fats. However, fiber and water are also very important macronutrients that we need in every diet. For this reason, I have extended the list of macronutrients to mirror the U.S. Department of Agriculture. It is important to understand the role that different macronutrients have in the body.

This page will give you a basic introduction to macronutrients. However, I encourage you to learn more about the role of each macronutrient by clicking on the related links. In this way, you can start developing a healthy low carb diet plan even if you are on a strict keto low carb diet.

1. Carbohydrates

The main roles of carbohydrates are to provide us with energy. However, an abundance of carbs are found in most of the foods that we eat. Once consumed, our body will convert and store the unused portion of energy to fat. And as a result, we gain weight. When we are not active, we need fewer carbs than when we are active. Learn more>>

2. Proteins (Amino Acids)

Proteins are the body’s main building block. Therefore, protein is essential for our body’s healing, repair, and growth of our hair, nails, and skin (inside and out). When we are severely injured, our body will need and use more protein to help repair itself. Learn more>>

3. Fats and Cholesterol 

Stored fat protects and insulates the body. However, there are many kinds of fats. Healthy fats do not cause high-cholesterol and are essential for vitamin absorption. While some cholesterol is needed to produce and regulate our sex hormones, an excess consumption of cholesterol can lead to health problems. The same is true for many of the fats that we eat.

4. Fiber

The important role of fiber is often unknown and overlooked. Fiber does much more than just keep use regular. Fiber actually help bad lower cholesterol, blood sugar levels, and blood pressure levels by regulating our net fat, sugar, and sodium intake. Plus, it makes us feel full longer and often provide a variety of micronutrients. Learn more>>

5. Water

Our body is made of mostly water. Therefore, water is essential for life. Water keeps us hydrated, improves blood flow, and help filter waste products and toxins from our body. High-quality water can also supply us with trace minerals. Learn more>>

Keep in mind that the different sources of carbohydrates, proteins, fats, fiber, and water are not all of the same nutritional quality. Some can be much more beneficial to our health than others. Especially since many foods overlap in the macronutrients and micronutrient density they provide.

For example, you could eat a teaspoon of sugar to get some carbohydrates in your diet. However, pure sugar is all you are getting. On the other hand, you could eat a small low carb fruit to meet your daily carb requirement. In this way, you will have also ingested a variety of vitamins, minerals, and beneficial fiber.

Whether we are on a low carb diet for weight loss, maintenance, body building, or health benefits, we all need to learn about counting macronutrients to maintain proper health. To do so, we must become familiar with our food nutrition label.
