What are macros in nutrition?

Macros, short for macronutrients, are the three nutrients that supply all the calories in food: protein, carbohydrates and fat. Protein and carbohydrates each provide about 4 kcal per gram, while fat provides about 9 kcal per gram. Your macro split is simply a breakdown of where your daily calories come from, which affects fullness, muscle retention and energy.

How do I calculate my macros for weight loss?

Start from your daily calorie target, usually about 500 kcal below your TDEE. Set protein first at roughly 1.6 to 2.2 g per kg of body weight, then set fat at about 20 to 35% of calories, and give the remaining calories to carbohydrates. Convert with 4 kcal per gram for protein and carbs and 9 for fat, then adjust after a few weeks.

How much protein do I need a day?

For adults who do resistance training, about 1.6 g per kg of body weight a day is a well-supported target. A 2018 meta-analysis in the British Journal of Sports Medicine found muscle gains plateaued around 1.62 g/kg, with some people benefiting up to about 2.2 g/kg. A 70 kg person would aim for roughly 110 to 150 g. People with kidney disease should ask their doctor first.

Is tracking macros better than counting calories?

It is a step up, not a replacement. Calories decide whether you gain or lose weight, while macros shape what that change is made of, such as how much muscle you keep and how full you feel. Beginners often do best counting calories for a few weeks, then adding a protein target, and only tracking all three macros once logging is a habit.

Do I need to hit my macros exactly every day?

No. Aim to land within about 10% of each target most days. Protein is the one worth prioritising; carbohydrates and fat can flex around it. Your body responds to your average over weeks, not any single day, so a close-enough log you keep every day beats a precise one you give up on after a week.

How to Track Macros: A Beginner's Guide

To track macros, set a daily calorie target, then split it into three numbers: protein (about 1.6 to 2.2 g per kg of body weight), fat (about 20 to 35% of calories) and carbohydrates (the remaining calories). Log meals daily and aim to land near each target. Protein and carbs have 4 kcal per gram; fat has 9.

If you have spent any time around fitness content, you have heard people talk about "hitting their macros" as if it were a second language. It sounds like it needs a spreadsheet, a food scale and a nutrition degree. It does not. Macro tracking is a slightly more detailed version of counting calories, and once you understand the three numbers it becomes one of the most useful habits you can build. This guide covers what macros are, how to set targets, what they look like on a Malaysian plate, and the least painful way to track them.

What are macros?

"Macros" is short for macronutrients, the three nutrients your body needs in large amounts and that supply all of your calories: protein, carbohydrates and fat. Everything you eat is some mix of these, plus water, fibre, vitamins and minerals.

Macro	What it does	kcal per gram	Local sources
Protein	Builds and repairs muscle, keeps you full, protects lean mass in a deficit	4	Chicken, eggs, fish, tofu, tempeh, dhal, ikan bilis
Carbohydrates	Main fuel for training and the brain	4	Rice, noodles, roti, bread, fruit, ubi
Fat	Supports hormones and vitamin absorption, adds flavour and fullness	9	Cooking oil, santan, peanuts, eggs, fatty meat

Fat carries more than twice the energy per gram of protein or carbs. That one fact explains why santan-heavy and deep-fried dishes are so calorie-dense, and why a spoonful of oil adds up faster than you would expect. Add up the calories from all three and you get your total intake: macros and calories are the same thing seen at different levels of detail.

Why track macros instead of just calories?

Counting calories tells you how much energy you eat. Tracking macros tells you where it comes from, and that affects how the weight change feels and what it is made of.

Picture two days at the same 1,800 kcal. On one, a good share comes from protein: eggs at breakfast, grilled fish at lunch, tofu and chicken at dinner. On the other, most of it is rice, noodles, kuih and sweet drinks. The scale may move the same, but the higher-protein day usually keeps you fuller and better protects muscle while you are in a deficit.

In short: calories decide whether you lose or gain; macros shape the quality of that change. If calorie counting is new to you, start with our guide on how many calories to eat to lose weight and add macros once that feels routine.

How do you set your macro targets?

Work in this order: protein first, fat second, carbs last.

Protein first. A widely used target for people who train is about 1.6 to 2.2 g per kg of body weight. A 2018 meta-analysis in the British Journal of Sports Medicine by Morton and colleagues, pooling 49 trials, found that gains in muscle from resistance training levelled off at around 1.62 g/kg a day, with the upper bound of their estimate near 2.2 g/kg. Higher intakes within that range are often used during fat loss to help keep muscle.
Fat second. Fat should not go too low because it supports hormones and absorption of vitamins A, D, E and K. The Malaysian Dietary Guidelines 2020 recommend 25 to 35% of energy from fat for the general population; 20 to 35% is a reasonable range if you train and want more room for protein.
Carbs last. Whatever calories remain go to carbohydrates. They are the most flexible lever: higher on training days, lower on rest days if that suits you.

To convert grams to calories: protein and carb grams × 4, fat grams × 9. The three should add up to your daily target.

For context, the same guidelines recommend 50 to 65% of energy from carbohydrate and 10 to 20% from protein for the general public. A high-protein split for fat loss will sit at the top of the protein range and may push carbs slightly below 50%. That is a common trade-off for people who train, not a rule everyone needs to follow.

These are starting points, not prescriptions. Adjust them using real feedback: your hunger, your energy, your training and your weight trend over a few weeks. If you have kidney disease, diabetes or another medical condition, are pregnant, or have a history of disordered eating, check targets with a registered dietitian or doctor first.

A worked example: 70 kg, desk job, wants to lose fat

Take someone who weighs 70 kg, works at a desk in KL, and lifts twice a week. Their maintenance is around 2,300 kcal, so they aim for about 2,000 kcal a day, a deficit of roughly 300 kcal.

Protein: 70 × 1.8 = 126 g, rounded to 130 g (520 kcal).
Fat: 28% of 2,000 kcal = 560 kcal, or about 62 g.
Carbs: 2,000 − 520 − 560 = 920 kcal, or 230 g.

The daily target is roughly 130 g protein / 230 g carbs / 62 g fat. The macro calculator runs this split for you from any calorie number, and the TDEE calculator gives you that number to start from.

Notice that 230 g of carbs is not low-carb. It leaves room for rice at two meals plus fruit, which is the point of setting targets instead of banning foods.

What do macros look like on a Malaysian plate?

Most macro guides are written around chicken breast and oats. Here is what common local dishes contain, based on lab analysis and Malaysian reference data. Preparation and portion sizes vary between stalls, so treat these as approximate.

Dish (serving analysed)	kcal	Protein	Carbs	Fat
Nasi lemak with sides (395 g)	~740	~36 g	~70 g	~36 g
Steamed chicken rice (412 g)	~780	~38 g	~87 g	~30 g
Char kuey teow (362 g)	~660	~15 g	~99 g	~23 g
Roti canai, 1 piece (84 g)	~266	~6 g	~40 g	~9 g
White rice, 1 plate (159 g)	~207	~4 g	~45 g	<1 g
Teh tarik, 1 mug (250 ml)	~140	~3 g	~22 g	~4 g

Nasi lemak, chicken rice and char kuey teow: Yeo et al., Foods 2021. Roti canai, white rice and teh tarik calories: Malaysian Dietary Guidelines 2020, Table 2.4; roti canai macros scaled from the Malaysian Food Composition Database; white rice and teh tarik macros are estimates.

Three things stand out:

Protein is the gap. Even a generous plate of nasi lemak or chicken rice gives you under 40 g of protein. To reach 130 g, almost every meal needs a deliberate protein source: an extra egg, more chicken, a piece of fish, tofu or tempeh.
Noodle and roti meals are carb-heavy and protein-light. A plate of char kuey teow gives about 15 g of protein for about 660 kcal. Two roti canai give roughly 12 g.
Drinks count. At about 140 kcal a mug, three teh tarik a day add around 420 kcal, mostly sugar, with almost no protein. Our guide to kopitiam drink calories shows how much you save by ordering kurang manis or kosong.

For a closer look at specific dishes, see nasi lemak calories and mamak food calories.

What macro split should you use for your goal?

Protein stays high across goals; what changes is total calories and how the rest is divided. These are common starting ranges for adults who train at least twice a week.

Goal	Calories	Protein	Fat	Carbs
Fat loss	~300 to 500 below TDEE	1.6 to 2.2 g/kg	20 to 30%	Remainder
Maintenance	At TDEE	1.4 to 2.0 g/kg	25 to 35%	Remainder
Muscle gain	~200 to 300 above TDEE	1.6 to 2.2 g/kg	20 to 30%	Remainder

If you are between two numbers, pick the one that is easier to hit consistently.

How do you actually track macros day to day?

This is where most beginners give up. The classic method is weighing every ingredient, looking each one up and entering grams by hand. It is precise and exhausting, and it does not work at a hawker stall.

There are two realistic options:

Photo or chat logging (fast). Photograph your meal or describe it in a sentence, and an app estimates the food, the portion and the macros. It is less exact than weighing, but quick enough to do at every meal. Our guide on how to count calories from a photo explains how accurate it is and how to improve the estimate.
Weighing (precise). A food scale plus manual entry is the most exact method and is worth it for competition prep or medical diets. For everyday tracking, most people find it more effort than it is worth.

A good middle ground: log every meal quickly, and weigh the few foods you eat most often a couple of times so you learn what 100 g of rice or chicken looks like.

What mistakes do beginners make with macros?

Chasing exact numbers. Landing within about 10% is the goal. Precision anxiety is the fastest route to burnout.
Setting protein too low. It takes deliberate effort, especially with rice- and noodle-based meals. Protect it first.
Fearing carbs or fat. Cutting fat too low can affect hormones; cutting carbs too low often hurts training. Both belong on your plate.
Forgetting cooking oil, sauces and drinks. They carry real calories, especially fat at 9 kcal per gram, and are the most commonly missed. Our list of calorie-counting mistakes that stall weight loss covers these in detail.
Quitting after one bad day. One off day is a rounding error over a month. Log the next meal and move on.

How do you get started?

Macro tracking comes down to a short list: know the three macros, set protein first and fill in the rest, log in a way you can keep up, and judge yourself on weekly averages rather than single days.

The easiest way to keep the habit is to make logging quick. Berry Best lets you log meals to Berry, its AI coach, by photo, text or voice, and shows protein, carbs and fat against your daily targets as you go.
