How Much Protein Per Day to Build Muscle? The Simple Answer
Here's the answer most articles bury under 1,500 words: eat 1.6–2.2 grams of protein per kilogram of bodyweight per day. For most adults who train, that lands somewhere near 1.8–2.0g/kg. That's it — that's the number.
The reason this question is everywhere is that a lot of people are trying to eat more protein but have never actually worked out their target. So they either guess low and stall, or chase a viral "200g" number that may not fit them. Let's fix that in two minutes.
Find your number
Take your bodyweight in kg and multiply by 1.6 (minimum) and 2.2 (upper end). Aim for somewhere in that band:
| Bodyweight | Daily protein target (1.6–2.2g/kg) |
|---|---|
| 60 kg / 132 lb | 96–132g |
| 70 kg / 154 lb | 112–154g |
| 80 kg / 176 lb | 128–176g |
| 90 kg / 198 lb | 144–198g |
| 100 kg / 220 lb | 160–220g |
Lean toward the top of the band if you're training hard, over 40, or in a calorie deficit — those are the situations where protein does the most work (building muscle, preserving it while cutting, keeping you full). Toward the bottom is fine if you're sedentary or just maintaining.
Want your full calorie and macro picture, not just protein? Run the TDEE calculator — it gives you the calorie boundary that protein sits inside.
The "30g per meal" myth
A rising worry is that your body can "only absorb 30g of protein per meal," so anything more is wasted. It isn't. Your gut digests and uses far more than 30g; what tapers off around ~30–40g is the muscle-building signal from one meal — not absorption. Excess protein still gets used (for other tissues, or as energy).
The practical takeaway isn't "cap your meals at 30g." It's that spreading protein across 3–4 meals is the easiest way to hit a high daily total and keep the muscle-building signal firing more often. Which is exactly why a simple meal structure beats one giant protein bomb.
What it looks like on a plate
You don't need to track every gram. Anchor each meal on 40–50g of protein from a real source — eggs and dairy, meat, fish, a tub of skyr — and you'll land near your target automatically. That's the entire idea behind the 4×50 Method: four meals, ~50g each, four different sources, ~200g total. No app required.

The two mistakes people make
- Aiming too low. "Getting enough protein" for general health is a much lower bar than the 1.6–2.2g/kg needed to build muscle. If you lift and you're not growing, this is usually why.
- Front-loading or back-loading it all. A 10g breakfast and a 90g dinner technically hits a number, but you'll be hungry all day and miss the per-meal signal. Even-ish across the day wins.
Get the daily number right, spread it across a few protein-forward meals, and you've solved the single most important nutrition variable for building or holding muscle — without counting anything else.
Frequently asked questions
Roughly 1.6–2.2g of protein per kg of bodyweight. An 80kg person targets about 128–176g a day. Go toward the higher end if you're training hard or in a calorie deficit, where protein matters most.
No — that's a myth. Your body digests and uses protein well beyond 30g in a sitting; what plateaus around ~30–40g is the muscle-building signal from a single meal, not absorption. Larger meals are still useful, but spreading protein across 3–4 meals is the more practical way to hit a high daily total.
About the same — 1.6–2.2g/kg either way. The difference is calories, not protein. In a fat-loss phase, keep protein high (it preserves muscle and keeps you full) and lower carbs or fats instead.
Not if you're a larger or heavily-training person — a 90–100kg lifter lands right in the 1.6–2.2g/kg range at ~200g. For a smaller frame it may be more than needed; scale it to your bodyweight.
Anchor each meal on 40–50g of protein from a real source and you'll land near your target without an app. Four protein-forward meals is the simplest structure that works.
