How Much Protein Do You Need to Build Muscle? A Practical Guide
Share
Protein is the most discussed and most misunderstood part of building muscle. Some people eat far less than they need and wonder why progress stalls. Others buy expensive powders and eat far more than their body can use.
This guide gives you a number you can work with, explains where that number comes from, and shows you how to reach it without rebuilding your entire diet.

The Short Answer
If you train with weights and want to build muscle, aim for 1.6 to 2.2 grams of protein per kilogram of bodyweight per day. In pounds, that is roughly 0.7 to 1.0 grams per pound.
For most people, the lower end of that range is enough. The upper end matters more if you are eating in a calorie deficit and want to protect the muscle you already have.
Work Out Your Own Number
| Bodyweight | Lower target (1.6 g/kg) | Upper target (2.2 g/kg) |
|---|---|---|
| 60 kg / 132 lb | 96 g | 132 g |
| 70 kg / 154 lb | 112 g | 154 g |
| 80 kg / 176 lb | 128 g | 176 g |
| 90 kg / 198 lb | 144 g | 198 g |
| 100 kg / 220 lb | 160 g | 220 g |
If you carry a significant amount of body fat, base the calculation on your target weight rather than your current weight. Fat tissue does not need protein to be maintained.
Why More Is Not Better
This is where a lot of money gets wasted. Research consistently shows that protein intake above roughly 2.2 g/kg does not produce additional muscle in trained individuals. The extra protein is simply used as energy or excreted.
Eating 250 g of protein when your body can use 160 g does not build more muscle. It makes your diet more expensive, more restrictive, and harder to sustain.
The people who make the fastest progress are usually not the ones eating the most protein. They are the ones who hit a reasonable number consistently, week after week.
Does Timing Matter?
Less than most people think, but it is not irrelevant.
The old idea of an "anabolic window" of thirty minutes after training has not held up well. What does appear to help is spreading your protein across the day rather than eating almost all of it in one meal.
A practical approach: three to four meals containing 25 to 40 g of protein each. That covers your daily total without any meal becoming enormous.
| Meal | Protein target | Example |
|---|---|---|
| Breakfast | 30-35 g | Greek yogurt bowl or protein oats |
| Lunch | 35-40 g | Chicken, rice and vegetables |
| Snack | 20-25 g | Cottage cheese or a protein shake |
| Dinner | 35-40 g | Fish, potatoes and salad |
Breakfast is where most people fall short. A typical cereal or toast breakfast delivers under 10 g. Fixing that one meal often closes half the gap on its own. If you want the reasoning behind that 30 g figure, we cover it in detail in do you really need 30g of protein at breakfast?

Where Your Protein Should Come From
Whole foods should make up the majority. They come with other nutrients, they keep you fuller, and they are usually cheaper per gram than supplements.
Efficient animal sources: chicken breast, turkey, lean beef, white fish, salmon, eggs, Greek yogurt, cottage cheese, quark, skyr.
Efficient plant sources: lentils, chickpeas, black beans, tofu, tempeh, edamame, seitan, high-protein pasta.
If you eat plant-based, aim for the upper end of the range and combine sources across the day. Plant proteins vary more in their amino acid profile, and the simplest way to handle that is variety plus a slightly higher total.
Do You Need Protein Powder?
No. It is a convenience, not a requirement.
Powder is useful when you struggle to reach your target with food alone, when you need something portable, or when you have little appetite after training. It is not useful as a replacement for meals you could reasonably eat.
If you do use it, treat it as one or two servings a day at most, and build the rest of your intake from food.
The Part That Actually Determines Your Results
Protein is necessary, but it is not sufficient. Muscle is built by the combination of four things:
- Progressive strength training - adding weight or repetitions over time
- Enough total calories - a small surplus, or at minimum maintenance
- Adequate protein - the number above
- Sleep and recovery - where the adaptation actually happens
If protein is the only one you get right, very little will change. This is the most common mistake we see: people optimise their macros to the gram while training inconsistently and sleeping five hours.
How to Actually Hit Your Number
Do not try to overhaul everything at once. Three steps, in order:
- Track for three days. Not forever - just long enough to see where you currently are. Most people are surprised by how far off their estimate was.
- Fix breakfast first. It is usually the weakest meal and the easiest to change.
- Add one protein-focused snack. That single addition typically adds 20-25 g without changing anything else.
Once those are habits, you will be close to your target without weighing anything. For practical options, see our 9 easy high-protein snacks and our 5 high-protein meal prep ideas.
Common Questions
Can too much protein damage your kidneys?
In people with healthy kidneys, higher protein intakes within the ranges discussed here have not been shown to cause damage. If you have existing kidney disease, this is a question for your doctor, not a fitness article.
Do I need protein on rest days?
Yes. Recovery and muscle repair happen on rest days. Keep your intake the same.
Will more protein make me gain fat?
Only if it pushes your total calories above what you use. Protein is not exempt from energy balance, but it is the most filling of the three macronutrients, which usually makes it easier to control intake overall.
What if I am eating in a calorie deficit?
Move towards the upper end of the range. Higher protein helps protect existing muscle when calories are restricted. We go through how to structure meals in a deficit in high-protein breakfast for fat loss.
What if my working hours change every week?
Structure your protein around your shift rather than the clock. See our guide to meal prep for shift workers.
A Note on Individual Circumstances
The ranges here apply to generally healthy adults who train with weights. If you are pregnant, managing a medical condition, taking medication that affects your metabolism, or have a history of disordered eating, speak with a doctor or registered dietitian before changing your intake or tracking food. Nothing in this article is medical advice.
