When I first started to lose weight, the first 50% of my weight loss was pretty accidental and quite easy if I am honest. I was simply eating less and moving more without really knowing what I was doing! After the first couple of stone had come off though, it became harder to lose weight, so I needed to step-up and take it a bit more seriously.
Calorie tracking I understood but I didn’t really have a clue about macronutrients, or why I needed to care about them.
“Macros” play an important role in health, muscle gain, weight loss, immunity and exercise performance.
Protein can help stop you feeling as hungry and helps with muscle growth. Who knew!? Because of this, protein seems to have become a go-to to mean “healthy” but quite often protein bars as an example, in health terms, are not much better than a regular chocolate bar! Carbs and fats are often considered “bad” which is simply not true. It can get quite confusing.
So, what are the macros and what do they do?
What Are Macronutrients?
Macronutrients are the nutrients our bodies require in large amounts to function correctly. They are the primary sources of energy for the body and have various roles in supporting growth, metabolism, and other physiological functions. The three primary macronutrients are carbohydrates, proteins, and fats.
1. Carbohydrates (Carbs)
- Source of Energy: Carbohydrates are the body’s main source of fuel. When you consume carbs, your body converts them into glucose (sugar), which is then used for energy.
- Types: There are two main types of carbohydrates: simple (sugars) and complex (starches and fibre). Foods like fruits, milk, and sweets typically contain simple carbs, while whole grains, vegetables, and legumes provide complex carbs.
- Dietary Importance: Complex carbs, especially those high in fibre, are recommended as they release energy slowly and help keep you full.
2. Proteins
- Building Blocks: Proteins are essential for growth and repair. They provide the body with what it needs to build and maintain its cells and tissues.
- Components: Proteins are made up of smaller units called amino acids. There are 20 different amino acids, of which nine are considered ‘essential’ because our bodies cannot produce them; hence, they must come from our diet.
- Sources: Meat, poultry, fish, dairy, eggs, legumes, and some grains are rich sources of protein.
3. Fats
- Energy Storage: While often maligned, fats are vital. They provide a concentrated source of energy, store vitamins, and protect our organs.
- Types: Fats can be categorised into saturated (found in animal products and some tropical oils), unsaturated (found in plants and fish), and trans fats (found in some processed foods).
- Essential Fats: Omega-3 and Omega-6 fatty acids are ‘essential’ fats that our body cannot produce. They play a critical role in brain function and growth.
Why Do Macronutrients Matter?
The balance and quantity of macronutrients consumed can significantly influence health, energy levels, and weight.
- Weight Management: Understanding and adjusting your macronutrient intake can help with weight loss, maintenance, or muscle building.
- Health Implications: The right balance can prevent nutritional deficiencies, reduce the risk of chronic diseases such as cardiovascular disease or diabetes, and support overall well-being.
- Energy and Performance: Athletes and those engaged in fitness training often adjust their macronutrient ratios to fuel their workouts and aid recovery.
Finding the Right Balance
There isn’t a one-size-fits-all answer to the ideal macronutrient distribution as individual needs vary based on age, activity level, goals, and health considerations.

In Conclusion
Macronutrients form the backbone of our diet, offering the energy and building blocks our bodies need to function optimally. As you navigate your health and dietary journey, understanding the role of carbs, proteins, and fats will equip you with the knowledge to make informed choices and tailor your diet to your unique needs.
