07.29 – Wednesday

Expanding from learning the different macronutrients, it’s important that we understand their roles within our diet and our bodies

Fats are one of two ESSENTIAL nutrients. Which means you must have them to live. While fats are used as an energy source, that is not their only function. They function as structural building blocks for cells, carry fat-soluble micronutrients (vitamins A, D, E, and K), as well as playing an essential role in proper hormone function. Hormones that affect your mood, hunger, cravings and energy levels, among other things. Fats are the most calorically dense of the three macros at 9 calories per 1g. More than double that of protein and carbs. Sources of fat include nuts and nut butter, seeds, cooking oils, avocado, dairy, and olives.

Protein is the second of the two ESSENTIAL nutrients. Protein’s primary role is to grow and repair tissues within the body. Protein is also your body’s longest-lasting fuel source. Every 1g of protein is 4 calories. Sources of protein include chicken, beef, fish, eggs, tofu, cottage cheese, and beans.

Carbohydrates are the one NON-ESSENTIAL macronutrient. Meaning we don’t “need” it to live. However, they are very important for optimizing performance and overall function. Carb’s primary role is as an energy source. In particular, glucose, which is the body’s preferred fuel source most often. Most forms of exercise, especially CrossFit style training will use carbs as a primary fuel source. Generally, the more active you are, the more carbs you need. Each 1g of carbs is 4 cal. Sources of carbs include potatoes, rice, whole grains, fruits, and veggies.
