Macros Explained: The Key to a Solid Physique

Updated: Jul 21, 2023

When it comes to achieving your body goals, understanding the role of macro nutrients is paramount. These essential components, consisting of proteins, carbohydrates, and fats, play a crucial role in fueling your body, supporting muscle growth, and influencing overall body composition. In this blog, we will explore the significance of macro nutrients in relation to energy levels, workouts, and achieving specific physique goals, while emphasizing the importance of adjusting their intake accordingly. At the end of the blog, we will also provide a FREE tool for you to use to get better insight into what your caloric and macronutrient goals should be, so stay tuned!


Proteins are the foundation for muscle growth, repair, and maintenance. They are composed of amino acids, which play a vital role in building and repairing muscle tissue. Protein intake aids in preserving lean muscle mass, enhancing metabolism, and reducing muscle breakdown during intense workouts and phases of being in a caloric deficit. To optimize muscle growth, consume around 0.8-1 grams of protein per pound of body weight daily. Adjust this range based on your specific goals—higher protein intake for fat loss and lower intake for muscle gain. This may seem contradictory, but we'll explain later.


Carbohydrates serve as the primary source of energy for our bodies, providing fuel for both our daily activities and intense workouts. They are broken down into simple sugars which are converted into glucose, which is readily available for immediate energy needs. Proper carbohydrate intake ensures optimal performance during workouts and prevents muscle fatigue. However, it's essential to choose complex carbohydrates like whole grains, fruits, and vegetables, which provide sustained energy release and vital nutrients. Tailor your carbohydrate intake based on activity levels, adjusting higher for intense training or reducing for weight loss goals. Shorter/ simpler carbohydrates or sugars can also be used for shorter, more instantaneous bursts of energy, however, these foods tend to be highly calorically dense and spike blood sugar and insulin levels. This quick spike in blood sugar and insulin can cause a drop in energy, commonly called a sugar crash.


Fats are the most often misunderstood nutrient, but, they are essential for overall health, hormone production, and nutrient absorption. While excessive fat intake can lead to weight gain, incorporating healthy fats such as avocados, nuts, and olive oil into your diet can promote satiety, improve brain function, and support hormone regulation. Aim for a moderate fat intake of around 20-35% of your total daily calorie intake, adjusting the ratio depending on your goals. Aim to get majority of your fats from healthy sources. We'll be posting a blog with more information on healthy fat sources in the near future.

Adjusting Macronutrients for Your Goals

Tailoring your macro nutrient intake to align with your specific goals is crucial. Although we're all told that it's all about protein, there's much more nuance to it than that.

If your goal is to gain muscle, it all starts with a caloric surplus. Eating more calories than you burn will ensure your body has enough nutrients to build new tissue. Specifically muscle tissue. In terms of protein, you should aim for about 0.8 g of protein per pound of body weight. Slightly lower protein while bulking will leave you more eating room to hit your caloric surplus. A higher carbohydrate portion will also keep you energized to help have effective workouts.

For fat loss, create a moderate caloric deficit by adjusting your carbohydrate and fat intake, while maintaining sufficient protein to preserve muscle mass. While in a cutting phase, it is advisable to increase your protein intake to 1-12g of protein per pound of body weight. This is for 2 reasons. 1 is because your body has a higher tendency to break down muscle when you're in a deficit. 2 is because higher protein intake will keep you fuller, preventing you from eating over your caloric limits.
