The nutrition basics that actually move the needle.

Macros, short for macronutrients, are one of the most powerful tools in building a healthy, results-driven diet. Whether the goal is fat loss, muscle gain, improved energy, or simply eating more balanced meals, understanding macros gives people the knowledge to fuel their body the right way.

Yet for many, “macros” still feels like a buzzword. This guide breaks them down simply and explains why focusing on them can transform the way people eat.

What Are Macros, Exactly?

There are three main macronutrients:

• Protein

• Carbohydrates

• Fats

Each one plays a different role in the body, and together they form the foundation of every meal. Unlike micronutrients (like vitamins and minerals), macros provide energy (calories) and structure how the body functions day to day.

1. Protein - The Repair + Recovery Macro

Protein is essential for:

• Muscle maintenance and repair

• Satiety (keeping you full)

• Hormone and enzyme production

• Recovery after training

It’s especially important when trying to lose fat or build lean muscle. Many people under-eat protein without realising and feel hungrier, more tired, and slower to see results.

Sources include: Chicken, beef, eggs, Greek yoghurt, tofu, legumes, protein powders.

2. Carbohydrates - The Body’s Main Energy Source

Carbs often get a bad rap, but they are the body’s preferred fuel source especially for the brain and during exercise. They support:

• Physical performance

• Mental focus

• Recovery and energy levels

Carbs also play a role in balancing hormones and mood. The key is choosing the right types and amounts.

Sources include: Oats, rice, fruit, starchy veg, legumes, wholegrain bread, pasta.

3. Fats - The Hormone + Brain Support Macro

Fats are vital for:

• Hormone production

• Brain health

• Absorption of fat-soluble vitamins (A, D, E, K)

• Long-lasting energy

While they are calorie-dense, healthy fats are essential for long-term health and should never be fully cut out.

Sources include: Avocado, nuts, seeds, olive oil, fatty fish, nut butters.

Why Do Macros Matter?

Balancing macros means:

• More stable energy

• Better appetite control

• Improved body composition

• Fewer cravings

• Sustainable results (no crash dieting)

Focusing on macros helps people build meals that actually work for their goals rather than relying on calorie counting alone or restrictive food rules.

So... How Do You Know What Macros You Need?

This is where personalised nutrition matters. Everyone’s macro needs are different, depending on:

• Body type and weight

• Activity level

• Goals (fat loss, maintenance, muscle gain)

• Lifestyle and preferences
