Have you ever heard someone say, “I’m cutting back on carbs,” or “I need to up my protein intake”? These statements all relate to macronutrients, the mighty trio of nutrition, known as macronutrients. These essential components are the backbone of a healthy diet and play crucial roles in maintaining our overall well-being. So, what are macronutrients, and how do they impact our bodies? In this blog post, we’re going to dive deep into what macronutrients are, why they’re important, and how to balance them for optimal health.
What Are Macronutrients
Macronutrients are the three primary nutrients that our bodies require in large amounts to function optimally: carbohydrates, proteins, and fats. They are called “macro” because your body needs them in large quantities to function correctly. Unlike vitamins and minerals (aka micronutrients) which are required in smaller amounts, macronutrients provide your body with the energy it needs to perform essential functions like breathing, heart pumping, and muscle movement. They’re basically the building blocks of our bodies, providing us with energy and helping with the formation of our cells and organs.
When it comes to measuring macronutrients, grams are the unit of choice. But the number of calories per gram varies depending on the macronutrient. Protein and carbs come in at a modest 4 calories per gram, but fat is the heavyweight here with a whopping 9 calories per gram! This means that a gram of fat packs more than twice the caloric punch of a gram of protein or carbs. So, when you hear talk about fat being more nutrient-dense, now you know why.
Importance of Macronutrients
It’s simple – the human body just plain needs macronutrients to grow, develop, and stay healthy. They give the body energy and the materials it needs to build cells, tissues, and organs. The metabolism, hormones, and other body processes are also controlled by macronutrients.
Without enough macronutrients, the body will be undernourished, tired, and have a weak immune system. Getting the right balance of macronutrients can also lower the risk of certain diseases, help you control your weight, and improve your overall health.
The body derives energy from proteins, fats, and carbohydrates. We could experience exhaustion and lack of strength to do everyday tasks if we don’t consume enough macronutrients.
Types of Macronutrients
Making mindful dietary choices starts with understanding these three macronutrient powerhouses and their critical roles in providing our bodies with ample nutrition.
Proteins: The Building Blocks of Life
Protein-packed diets seem to be all the rage these days and for good reason. They’re considered a building block of life that help create muscle, tissues, hormones, and enzymes. As the most satiating macronutrient, protein helps keep us feeling full for longer, making it a key player in weight management.
Proteins can be found in most foods, and are essential for maintaining a healthy diet. Protein intake for a sedentary adult should be 0.8 g/kg (or 0.36 g/lb) of body weight. That works out to roughly 56 grams of protein per day for the typical inactive male and about 46 grams for the typical sedentary female.
Key Functions of Protein:
- Protein is an essential macronutrient that plays a key role in maintaining and building body tissue. It is made up of amino acids, which are the building blocks of cells and are used to make enzymes, hormones, and other molecules.
- Proteins play a critical role in tissue healing and regeneration. It is also used for energy, though it is not as efficient as carbohydrates.
- Hormones such as insulin, growth hormone, and thyroid hormone are all made from proteins. These hormones help the body stay in a steady state of homeostasis.
Sources of Protein:
Protein can be found in a variety of sources including animal products and dairy, as well as plant-based sources. Animal sources of protein include beef, pork, poultry, fish, and eggs. Dairy products such as milk, cheese, and yogurt are also good sources of protein. For those following a vegetarian or vegan diet, plant-based proteins like beans and lentils are an excellent source of protein. Nuts and seeds such as almonds, walnuts, and chia seeds are also excellent sources of vegan-friendly protein.
Carbohydrates: The Body’s Preferred Fuel
Carbohydrates often get a bad rap, but they are actually an essential component of a healthy diet. Carbs are the body’s preferred source of fuel and are critical for energy production. That being said, it’s important to choose the right kinds of carbohydrates – such as whole grains, fruits, and vegetables – as opposed to processed and refined options like sugary snacks and white bread. Additionally, different individuals may have varying carbohydrate needs depending on their activity levels and health goals, so it’s important to work with a healthcare professional to determine the right balance for you.
Carbohydrates are broken down into glucose, which is used by cells for energy. They also provide dietary fiber, which helps to regulate digestion and may reduce the risk of certain chronic diseases.
Key Functions of Carbohydrates:
- Carbohydrate foods provide our bodies with energy, helping us to stay energetic throughout the day.
- They also help to regulate blood sugar levels, which is important for maintaining overall health and well-being.
- Finally, they are an excellent source of fiber, vitamins, and minerals that help keep our digestive systems working properly.
Sources of Carbohydrates:
Carbohydrates can be found in a wide variety of sources, including grains, fruits, and vegetables. Whole-grain foods like oats, quinoa, and brown rice are excellent sources of complex carbohydrates. Fruits and vegetables such as apples, bananas, and potatoes are also great sources of carbs. You’ll want to avoid processed and refined sources of carbohydrates such as white bread, sugary snacks, and soda.
Fats: More Than Just a Culinary Villain
While it’s easy to demonize dietary fat, it’s actually an essential part of a healthy diet. Fats play a crucial role in nutrient absorption, hormone production, and brain function, and they’re also key for healthy skin and hair. But, as with carbs, not all fats are created equal. Consuming too many unhealthy fats like trans fats and saturated fats can increase your risk of heart disease, while consuming healthy fats like omega-3 fatty acids can have significant health benefits.
Key Functions of Fats:
- Fats are an important source of energy and can help you feel full longer.
- They also help your body absorb vitamins A, D, E and K, which are essential for maintaining healthy bones, vision, and immune function.
- Fats also play a role in hormone production, as well as brain development.
Sources of Fats:
Healthy fats can be found in a variety of sources, such as nuts and seeds, avocados, olive oil, fatty fish like salmon and tuna, nut butter, and eggs. Dairy products such as yogurt and cheese also contain healthy fats. Unhealthy sources include processed snacks like chips, fast food, and fried foods.
Macronutrient Ratios
Now that we’ve looked at each macro individually, it’s important to remember that balance is key. Your macronutrient ratios will depend on your individual health, age, gender, and overall activity level. Generally speaking, a well-balanced diet (recommended by USDA) should consist of 45-65% carbohydrates, 10-35% protein, and 20-35% healthy fats.
Each individual’s dietary needs are best determined through a tailored strategy considering their unique situation. Individuals can improve their health and well-being by working with a qualified dietician or healthcare provider to fulfill their specific requirements. Some of the procedures involved in identifying each person’s requirements are as follows:
- Estimate your daily energy use
- Check your macronutrient intake
- Identify deficiencies in micronutrients
- Taking health issues into account
Macro Ratios for Athletes
When it comes to achieving optimum athletic performance, macro ratios are a critical component of your fueling strategy. The right balance of carbs, protein, and fat can boost your energy, enhance your performance, dial in your weight, and help build muscle to help you reach your fitness goals.
Weight Loss
To hit or perfect race weight, occasionally we’ll need to drop a few pounds. In actuality, you can become slimmer on any diet plan as long as you are constantly consuming fewer calories than your total daily expenditure. This means that the number of calories consumed each day should be less than what your body burns in a single day. A balanced diet consisting of 40% carbs, 30% protein, and 30% fat can support weight loss and provide the energy needed for activity. If you’re exercising one to two hours daily, you should dial up your carbs a bit and shoot for a ratio of 45% carbs, 30% protein, 25% fat, 45% carbs.
Muscle Building
Gaining muscle is fundamentally different than losing weight – the key factor here is caloric surplus. Without additional calories, it’s nearly impossible to gain muscle strength. It’s no surprise that gaining muscle requires a higher protein intake to aid muscle growth and repair. The 45–65% carbohydrate, 30–35% protein, and 20–35% fat ratio suit muscle building since it prioritizes carbohydrate use for energy and protein for muscles. Keep in mind that eating a surplus of protein doesn’t really build more muscle. Studies show that your body can only really process 20-25g of protein with each meal. And consuming too much protein can be useless or even harmful.
Endurance Athletes
It may be necessary for endurance athletes to consume more carbohydrates to support their lengthy, intense workouts. A ratio of 50–65% carbohydrates, 10%–25% protein, and 20–30% fat provides enough carbohydrates for long-lasting energy during exercise as well as enough protein and good fats for overall health and muscle preservation. For lighter days or rest days, cutting your carb intake to 50% offers a healthier balance of fats and proteins. However, in order for you to stay strong and energized during those tough training sessions, it’s important that you keep your carbohydrate consumption high so that your body has the fuel it needs to perform at its best.
