Macro tracking has a reputation for being the serious version of calorie counting. Mostly it is the same thing with more arithmetic, and for most people the extra arithmetic buys one useful thing: enough protein.
That is not an argument against it. It is an argument for doing it in the right order, so you get the benefit without the spreadsheet.
Here is the whole process.
Step 1: get your calorie target first
Macros are a division of your calories, so the calorie figure has to exist before the split means anything.
Use the how many calories should I eat calculator for a maintenance figure and a target, or the TDEE calculator if you want the workings. If none of the terminology is familiar yet, TDEE vs BMR explained is fifteen minutes well spent.
Everything below assumes you have one number to divide.
Step 2: set protein, and set it first
Protein is the macro with a genuine target. The other two are what is left over.
1.6–2.2 g per kilogram of bodyweight is the research consensus for people who train. Sit at the higher end while cutting, because a deficit is exactly when muscle is at risk. If you are not training at all, 1.2–1.6 g/kg is plenty.
For a 70 kg person, that is roughly 110–155 g a day.
Two reasons it comes first. It is the most filling of the three, which makes a deficit meaningfully easier to hold. And it is the one that determines whether the weight you lose is fat or muscle. How much protein do you need has the detail, and the protein calculator will give you a number.
Step 3: set fat, then let carbs take the remainder
Fat has a floor rather than a target: roughly 0.6–0.8 g per kilogram, or about 20–30% of calories. Below that, hormones and the absorption of fat-soluble vitamins start to suffer, and food gets considerably less pleasant.
Carbohydrate is then simply what is left. Not because carbs do not matter — they fuel training and they are most people's main energy source — but because there is no evidence-backed minimum in the way there is for protein and fat.
Worked example, 70 kg, 2,000 calorie target:
| Macro | Target | Calories |
|---|---|---|
| Protein | 140 g | 560 |
| Fat | 55 g | 495 |
| Carbs | remainder — 236 g | 945 |
Protein and carbs are 4 calories a gram, fat is 9. That is the entire arithmetic. The macro calculator does it if you would rather not.
Step 4: track protein properly, the rest loosely
This is the step that separates people who sustain macro tracking from people who quit in three weeks.
Chasing three numbers to a tight tolerance at every meal is genuinely hard and mostly pointless. Chasing one is easy.
Hit protein. Stay near your calories. Let carbs and fat land where they land.
If calories are right and protein is right, the carb and fat split is very unlikely to be the thing standing between you and your goal — macros matter far less than the calorie total for body composition, once protein is handled.
In practice: check protein at lunch. If you are behind, the evening meal gets a protein-heavy build. That single habit does most of the work.

Step 5: build meals that hit protein without effort
Targets are easy to set and harder to reach, particularly on a vegetarian diet. The fix is structural, not motivational: put a protein anchor in every meal and the daily total takes care of itself.
| Food | Serving | Protein |
|---|---|---|
| Chicken breast | 100 g | ~31 g |
| Soya chunks, dry | 50 g | ~26 g |
| Whey protein | 1 scoop | ~24 g |
| Paneer | 100 g | ~18 g |
| Greek yoghurt | 150 g | ~15 g |
| Tofu | 100 g | ~12 g |
| Rajma / chole, cooked | 1 katori | ~8 g |
| Egg | 1 large | ~6 g |
| Dal, cooked | 1 katori | ~6 g |
| Curd | 1 katori | ~4 g |
| Roti | 1 | ~3 g |
The uncomfortable fact for vegetarian tracking is that dal is a much weaker protein source than its reputation — a katori is about one egg. High-protein Indian vegetarian foods works through what actually moves the number.
Step 6: review weekly, adjust monthly
Look at the week, not the day. Individual days swing for reasons that have nothing to do with your diet.
What to look at:
- Average calories against target. Within about 100 is fine.
- Average protein against target. This is the one to actually fix.
- Weight trend over three weeks, never a single morning.
Adjust calories by 100–150 if the trend is wrong for three consecutive weeks. Leave the macro split alone — if something is not working, it is almost never the carb-to-fat ratio. Not losing weight in a deficit goes through the real causes in order.
Common mistakes
Setting protein from goal weight when you are very light. Use current bodyweight unless you are carrying a lot of fat, in which case goal weight or lean mass avoids an absurd number.
Treating carbs as the enemy. Cutting carbs while keeping calories identical does nothing for fat loss. It does make training worse.
Tracking macros before you can reliably track calories. Three numbers is harder than one. Get a month of consistent calorie logging first, then add protein, then add the rest if you still want it.
Weighing everything to hit macros exactly. Being within 10% consistently is enough. You do not need a scale for this.
Frequently asked questions
What is the best macro split for fat loss?
Protein at 1.6–2.2 g per kg of bodyweight, fat at roughly 20–30% of calories, and carbohydrate taking the remainder. Beyond hitting protein, the exact carb-to-fat ratio has very little effect on fat loss when calories are equal.
Do I need to track macros or just calories?
Calories drive weight change; protein drives what that weight is made of. If you track only one thing, track calories. If you track two, add protein. Carbs and fat are worth watching mainly to make sure fat does not fall too low.
How much protein do I need per day?
Around 1.6–2.2 g per kilogram of bodyweight if you train, towards the top of that while in a deficit. Without training, 1.2–1.6 g/kg is sufficient. For a 70 kg person that is roughly 110–155 g a day.
Is it bad to go over on carbs?
Not in itself. Going over on carbs matters only insofar as it puts you over on calories. If the calorie total is right and protein is met, a high-carb day is not a problem.
How exactly do I need to hit my macros?
Within about 10% on protein and calories is plenty. Carbs and fat can float freely. Precision beyond that costs a great deal of effort and buys results nobody can measure.
Can you track macros without weighing food?
Yes. Hand portions and standard servings get you close enough, and protein sources are unusually easy to estimate because they tend to be discrete — an egg, a scoop, a palm of chicken, a katori of rajma.
