What are Macros? The Building Blocks of Your Diet

What are macros and what do they do?

In every diet and for every weight loss goal there are three major macro nutrients that affect how (and yes, if) we reach our goals. The building blocks of every diet are fats, carbs, and proteins. Many people find counting macros to be helpful in building flexible and sustainable diets, without restrictive unhealthy behaviors. So what are these macros? Why do they matter for health and weight loss, and does the type of macros really matter?

Proteins

While proteins aren’t usually used for fuel, they are an important part of the diet. Consuming protein is critical to healing and building tissue in the body. That’s why when doing a hard workout it’s important to consume protein to assist the body in recovery. Proteins come in two types: plant based and animal based. Animal based proteins are all the proteins that probably come to mind when you think of eating protein: meat, chicken, dairy, eggs. But many plants are also high-protein and a great alternative protein source. Chickpeas, beans, lentils, edamame, tofu, and seitan are just a few examples.

Fats

Fats help your body store vitamins and take part in building hormones such as cholesterol, testosterone and estrogen. When you consume high quality fats, such as those found in nuts, avocados, olives, and fish, your body is better able to store the nutrients you consume from your other macros. Just like there are different types of carbs, there are also different types of fats.

The four major types are saturated fat, trans fat, monounsaturated fat, and polyunsaturated fat. The healthiest types of fats are monounsaturated (like in avocados) and polyunsaturated (like in fish). Saturated fats are the kinds of fats found in animal products, and in excess can be unhealthy for the heart. Trans fats are the worst form of fats and while they are sometimes found in animal products as well, they are most unhealthy in the form of partially hydrogenated oils. These are vegetable oils that have been chemically altered to stay more solid at room temperature. Snacks foods and fats foods are notoriously high in trans fats.

Carbs

The macro we most often hear about in popular culture and surrounding the weight loss discussion is of course carbs. But believe it or not, carbs are not all bad. In fact, carbs are an absolutely necessary component of any sustainable weight loss and health program. Carbs provide the body with the most easily accessible energy and also play an important role in healthy brain activity. But some carbs are better than others.

Complex carbs are better for someone trying to lose weight as they are composed of longer, more complex sugar molecules, meaning your body takes a longer time to break them down. This leaves you feeling fuller for longer. Simple carbs, on the other hand, are broken down quickly by the body for immediate use. Complex carbs are found in foods like vegetables, beans or whole grains, and simple carbs are found in fruits, sugars, and syrups. That quick breakdown of the simple carbohydrates explains why when we consume a candy bar, we sometimes get a “sugar rush.”

Every body needs a different amount of carbs, and your metabolic flexibility — your body’s ability to use fats or carbs as a source of fuel or switch between the two — will determine how efficiently you body uses the carbs you consume. Another factor that affects how your body breaks down marcos, especially carbs, is your timing. A balanced diet of marcos should space out the carbs, proteins, and fats throughout the day. Similarly, proper timing of carb intake can make a huge difference in a weight loss transformation.

If your goal is to lose weight, it’s important to get a good understanding of how your metabolism operates. Products like Lumen can help you understand how carbs affect your metabolism. For some, it is critical to consume a higher carb intake several times a week, and a low carb intake on other days. A successful diet is about finding the proper balance of macros to meet your fitness or weight loss goals.
