How Much Protein Do I Need?
Everyone overcomplicates this. There is one number that matters, it is easy to work out, and most people eat about half of it. Here is exactly how much protein you need and how to actually get it.
If you only fix one thing about how you eat, make it protein. Not because protein is magic, but because it quietly does three useful things at once: it keeps you full, it protects your muscle while you lose fat, and it costs your body more energy to digest than carbs or fat. When I went from 128kg down to 86kg, getting enough protein was the single change that made the deficit bearable instead of miserable.
So let me answer the question straight, then explain it.
The number you actually need
Eat 1.6 to 2.2 grams of protein per kilogram of your goal body weight, every day.
That is the whole answer. Goal weight, not current weight. If you are 100kg and want to get to 80kg, you work off 80, not 100. So that is roughly 128g to 176g of protein per day. Most people who are trying to lose weight do fine aiming somewhere in the middle, around 1.8g per kg.
Here is what that looks like for different goal weights:
| Goal weight | Lower (1.6g/kg) | Higher (2.2g/kg) |
|---|---|---|
| 60 kg | 96 g | 132 g |
| 70 kg | 112 g | 154 g |
| 80 kg | 128 g | 176 g |
| 90 kg | 144 g | 198 g |
If you prefer pounds, the rough version is about 0.7 to 1 gram of protein per pound of goal bodyweight. Same target, different unit. You do not need to be precise to the gram. Get within 20g of the target most days and you are winning.
Why protein matters more when you are dieting
When you eat in a calorie deficit, your body looks for energy to make up the gap. You want it to pull that energy from fat. The problem is that the body will happily break down muscle too if you let it, especially if you are not giving it a reason to keep that muscle around.
Two things tell your body to hold onto muscle: lifting weights, and eating enough protein. Skip both and a chunk of the weight you lose will be muscle, which is exactly the stuff that makes you look lean and keeps your metabolism up. That is the "skinny fat" outcome nobody wants. Hit your protein and train a bit, and far more of what you lose is actual fat.
This is also why the deficit feels easier with more protein. Protein is the most filling of the three macros by a mile. A 200 calorie chicken breast keeps you satisfied way longer than 200 calories of rice or biscuits. When people tell me they are "starving" on their diet, nine times out of ten they are eating mostly carbs and barely any protein.
How to actually hit your protein target
Knowing the number is easy. Hitting it is where people fall short, usually because they have no idea how little protein is in the food they eat. A plate of nasi goreng feels heavy and filling but might only have 12g of protein in it. Here is what real protein looks like:
| Food | Amount | Protein |
|---|---|---|
| Chicken breast | 150 g cooked | ~46 g |
| Eggs | 2 large | ~12 g |
| Canned tuna | 1 tin (drained) | ~25 g |
| Greek yogurt | 170 g tub | ~17 g |
| Firm tofu | 150 g | ~17 g |
| Dhal (cooked) | 1 cup | ~18 g |
| Protein powder | 1 scoop | ~24 g |
The trick is simple: anchor every meal around a protein source first, then build the rest of the plate around it. Most people do it backwards. They fill the plate with rice and noodles and then add a small piece of meat as an afterthought. Flip it. Decide your protein, then add the carbs and vegetables.
A normal day might look like two eggs and yogurt at breakfast, a tin of tuna or some chicken at lunch, and a proper portion of meat or tofu at dinner. That alone gets most people to 100g without trying hard. Add a scoop of powder on a busy day and you are at 124g. None of this is exotic. It is just deciding that protein comes first.
If you want to see how protein stacks up in the food you already eat, browse the Malaysian food calorie database. Every dish lists its protein along with calories, so you can spot which of your usual meals are pulling their weight and which are just carbs in disguise.
Do you need protein powder?
No. Powder is a convenience, not a requirement. It is just dried milk protein in a tub. Useful when you are busy or travelling, or when you genuinely cannot be bothered to cook. But if you eat enough real food, you will never need it. Do not let anyone convince you that the powder is doing something special. It is not. It is food, in powder form, and usually cheaper protein per gram than chicken, which is its only real selling point.
Can you eat too much protein?
For a healthy person, no, not in any way you need to worry about. The "protein wrecks your kidneys" thing is a myth for people with normal kidney function. If you eat more protein than your body can use, it just burns it for energy or gets rid of the rest. The only real downsides are that it costs more money and it crowds out room for other food. There is also no extra muscle benefit much past 2.2g per kg, so going to 3g per kg is just wasting chicken.
Protein first, then everything else. That one habit fixes more diets than any supplement ever will.
So that is it. Work out 1.6 to 2.2g per kg of your goal weight, build every meal around a protein source, and stop stressing about the decimal points. If you have not worked out your overall calorie target yet, do that next. Use the calculator on the homepage, it gives you both your daily calories and your exact protein number in about two minutes. Then go eat your chicken.
