What are Macronutrients?

Macronutrients are carbohydrates, fats, and protein. The amount of each macronutrient should follow that they all are equal and enough for the body to fully function.


Macronutrients are carbohydrates, fats, and protein. Our body requires these macronutrients for it to be in a good state. These nutrients provide calories that are needed to provide energy for our body. Let us get to know each macronutrient and its function in our body.


Carbohydrates are known in all men as the culprit for obesity, diabetes, and heart ailments. People try as hard as they can to shun carbohydrate-rich food. However, you should not skip eating carbohydrate-rich food (unless you are committed to a keto diet) because it is an important nutrient for your body to take. The human body relies on the macronutrient carbohydrate to provide energy in the body.

Carbohydrates are composed of sugar molecules. Sugar molecules are present in almost all the food that we eat (examples of it are fruit, milk, unprocessed food, and so on and so forth). Most plants too are composed of sugar. These sugars are extracted and are processed to be refined or unrefined sugar.

Glucose, a form of carbohydrate is a preferred carbohydrate to be processed by the liver and provide energy for the nervous system. If there is an excess of glucose in our body, the excess glucose is stored in the liver and in the skeletal system in the form of glycogen (stored in fat). When sometime in your system, your glucose level decreases, the liver will break down the remaining glycogen to augment the glucose loss.

If the body has no glucose or fat to burn to produce energy, the next option of the body is to burn protein and convert its amino acid contents into glucose. This last resort of our body may have an adverse effect on our immunity and muscles. This is why it is quite critical to maintain the level of glucose in our body. The acceptable amount of carbohydrates in our body is at least 45% to 65% of the calorie intake. Some people overdo it and go beyond the threshold that that body can only hold. This leads to carbohydrate induced ailments like high blood sugar, and so on and so forth.


Meat is said to be the primary source of protein. It even is the central focus on our meals. However, most people overeat proteins than what their bodies require them to eat. Actually, even if you do not have meat in your daily servings, you can still meet the amount of protein that your body needs daily.

Protein is one of the macronutrients our body needs. Unlike carbohydrates, the primary role of protein is not to produce energy but it can also be used as a source of it. It has many roles in fact. The protein has different kinds of it, each has its function in our body. Protein can be in a form of enzyme. Enzymes help in the million chemical processes in our body. Proteins can also be in a form of hormones.

Hormones are messengers that gives instructions as to what organs should do. They are the regulators of organ activities in our body. Proteins are also considered as the building blocks of the human physiology. The protein gives shape and structure in our body. Our bones, teeth, hair, and so on and so forth are composed of proteins. Proteins serve as antibodies too. Your immune system will not work properly unless proteins are there. Proteins also regulate fluid balance in our body.

Proteins also serve as buffers. They balance out the acidity, alkalinity, or the base level of the fluid inside our body. Balancing them is important as if one of them exceeds, it will create unfavorable outcomes. As mentioned above, protein is the last resort of our body to produce energy. It has its adverse effects because your body is sacrificing the precious proteins it has for energy even though there is a lot of function it needs to do.


Dietary fat is important in our body. It serves as the secondary resort of our body to burn as fuel to produce energy. Fats are in short, energy reserves. Your liver will use fat to produce energy when you are low in carbohydrates usually during the times where you are sleeping or while exercising. Fat is the source of fatty acids. Fatty acids are what our cell membranes constitute. Fatty acids also serve as chemical regulators of our body.

Saturated and the Unsaturated Fat

There are two kinds of fat. The saturated and the unsaturated fat. High intakes of saturated fats might lead to an increase in LDL or low-density lipoprotein or bad cholesterol. Having too much LDL in our blood can lead to heart diseases. Studies tell us that unsaturated fat intake is a healthier way to include in our diet. Unsaturated fatty acids improve the level of insulin sensitivity and in turn the decrease in the level of blood cholesterol.

Monounsaturated and Polyunsaturated Fats

There are two kinds of unsaturated fatty acids; the monounsaturated and polyunsaturated fats. Sources of the monounsaturated fatty acids are olive oils, canola oils, nuts, olives, seeds, avocados, and so on and so forth. Polyunsaturated fats, on the other hand, can be found in omega-3 rich food which can be found in walnuts, flaxseed, tofu, walnut oils, soybean, and so on and so forth. Polyunsaturated fatty acids are important in our body because it has a role in preventing heart diseases. The fatty acids of polyunsaturated fat are also key in the development of the fetus in pregnant women. Also, they decrease the possibility of having arthritis and other inflammatory diseases. Most of these types of fatty acids can be found in tuna, sardines, herring, mackerel, salmon, and so on and so forth.

Most of the advertisers lead us to believe that fats are bad for our health. Fat is a macronutrient to which our body gets a lot of bodily functions. Do not fear it. Do not entirely erase it in our daily dietary intake. The technique is, you just need to choose wisely on what kind of fat will go eat. Now that you know what kind of fats are good and fat, be an intelligent consumer and select to your body’s benefit.
