What Are Macros? (And Why Everyone's Tracking Them)

You've probably heard people at the gym talking about "hitting their macros" or seen someone pull out their phone to log their lunch. Maybe you've wondered what all the fuss is about, or if you should be doing it too.

Here's the simple answer: macros are the three types of food that make up everything you eat. Understanding them helps you eat better for your goals, whether that's building muscle, losing fat, or just having more energy.

Let's break it down in the simplest way possible.

The Three Macros: Protein, Carbs, and Fats

Image prompt: Mid-century retro-futurist illustration of person confidently reading food label in bright grocery store. Figure standing upright with shopping basket, examining package with purposeful expression, well-stocked colourful shelves surrounding them, open spacious aisle. Clean vector shapes, flat colours, limited palette (cream, dark brown, coral orange, sage green). Simplified forms, poster-style composition, optimistic informative tone. No texture, no gradients, no photorealism, no text.

Every food you eat is made up of three main components called macronutrients, or "macros" for short:

Protein builds and repairs your muscles, keeps you full, and helps your body function properly. You find it in chicken, fish, eggs, Greek yogurt, protein powder, and beans.

Carbohydrates give you energy for your workouts and daily activities. They fuel your brain and muscles. You find them in rice, bread, pasta, oats, fruits, and vegetables.

Fats support hormone production, help you absorb vitamins, and keep you satisfied after meals. You find them in oils, nuts, avocados, butter, and fatty fish.

That's it. Every single thing you eat is some combination of these three macros (plus water and micronutrients like vitamins and minerals, but those aren't macros).

A chicken breast is mostly protein with a bit of fat. Rice is almost all carbs. Peanut butter is a mix of fats and protein with some carbs.

Why Macros Matter More Than Just Calories

You've probably heard "calories in, calories out" for weight loss. That's true, but it's not the whole story.

Two meals can have the exact same calories but completely different effects on your body:

Meal A: 500 calories from a chocolate bar (mostly carbs and fats, almost no protein)
Meal B: 500 calories from grilled chicken, rice, and vegetables (balanced protein, carbs, and fats)

Both are 500 calories, but:

• Meal B keeps you full for hours, Meal A leaves you hungry in 30 minutes
• Meal B helps you build and maintain muscle, Meal A doesn't
• Meal B gives you steady energy, Meal A spikes your blood sugar then crashes

This is why people track macros instead of just counting calories. The type of calories matters just as much as the total amount.

When you track macros, you're making sure you're getting enough protein to support your training, enough carbs to fuel your workouts, and enough fats to keep your hormones working properly.

What Each Macro Does for Your Body

Protein:

• Builds and repairs muscle tissue after workouts
• Keeps you feeling full longer than carbs or fats
• Supports immune function and hormone production
• Helps preserve muscle when you're trying to lose fat

Carbohydrates:

• Primary fuel source for high-intensity exercise
• Replenishes glycogen (stored energy) in your muscles
• Keeps your brain functioning properly
• Supports training performance and recovery

Fats:

• Produces hormones (including testosterone and oestrogen)
• Helps absorb vitamins A, D, E, and K
• Provides backup energy for lower-intensity activities
• Supports cell structure and brain health

You need all three. Cutting out an entire macro (like going zero-carb or zero-fat) usually backfires because your body needs each one for different essential functions.

Do You Actually Need to Track Macros?

Honestly? Not everyone needs to track macros. Here's a simple guide:

You probably need to track if:

• You're trying to build muscle and not seeing progress
• You're trying to lose fat and the scale won't budge
• You're an athlete with specific performance goals
• You have specific body composition targets
• You've been "eating healthy" but not getting results

You probably don't need to track if:

• You're generally active and happy with how you look and feel
• You're eating whole foods and your energy is good
• You don't have specific fitness goals beyond "stay healthy"
• The idea of tracking food stresses you out significantly

Tracking macros is a tool, not a requirement for being healthy. Some people benefit enormously from the structure and data. Others do perfectly fine eating intuitively without tracking anything.

The people you see tracking everything at the gym? They usually have specific goals (compete in bodybuilding, make a weight class, get very lean) that require precision. If that's not you, you might not need that level of detail.

The Basic Macro Split (What Most People Aim For)

While everyone's needs are different, here's a general starting point that works for most active people:

Protein: 30-40% of your calories (or about 0.8-1g per pound of bodyweight)
Carbs: 30-40% of your calories
Fats: 25-35% of your calories

These aren't strict rules. Some people do better with more carbs (endurance athletes), some with more fats (people who feel better on lower carb). These are just common starting points.

We'll cover exactly how to calculate your specific numbers in Part 2 of this series.

What This Looks Like in Real Food

Here's a simple balanced meal that hits all three macros:

Grilled chicken breast (protein: 40g)
Brown rice (carbs: 45g)
Roasted vegetables with olive oil (carbs: 10g, fats: 15g)

Or for breakfast:

Scrambled eggs (protein: 20g, fats: 15g)
Oatmeal with berries (carbs: 40g, fats: 5g)
Buffee's coffee with Joyya milk (protein: 10g, minimal carbs and fats)

See how every meal naturally contains a mix of macros? You're already eating this way, tracking just means being intentional about the amounts.

The Coffee Connection

This is where Buffee's comes in. Regular coffee is basically zero macros (just caffeine and water). But once you add milk, you're adding macros to your day.

A standard latte with regular milk:

• Protein: 6-8g (not much)
• Carbs: 12-15g (mostly lactose sugar)
• Fats: 5-8g

A Buffee's coffee with protein-enriched milk like Joyya:

• Protein: 15-20g (significant contribution to your daily target)
• Carbs: 8-10g (lower than regular milk)
• Fats: minimal

When you're tracking macros, your coffee counts. Choosing a macro-friendly option means you're getting quality protein with your caffeine instead of just liquid calories.

What's Next

Now you understand what macros are and why people track them. In Part 2, we'll show you exactly how to calculate your specific macro targets based on your bodyweight and goals. No complicated formulas, just simple math anyone can do in five minutes.

For now, just start noticing the macro breakdown of what you're already eating. Most food labels list protein, carbs, and fats right on the package. You're probably already eating a decent balance without realising it.
