# How much protein to build muscle

> To build muscle, most people need 1.6–2.2 g of protein per kg of bodyweight per day, split across 3–4 meals of roughly 0.4 g/kg each. Total daily protein matters most; timing is secondary.

Protein is the single most important nutrient for building muscle. Get the daily total right and you've solved most of the nutrition puzzle.

## Your daily target

The evidence points to **1.6–2.2 g of protein per kg of bodyweight per day** for building or preserving muscle. Within that range:

- Lean toward the **higher end** when dieting (to protect muscle) or chasing maximum growth.
- The **lower end** is fine for general health and maintenance.

For an 80 kg person, that's roughly 130–175 g per day. Get your exact target from the [protein calculator](/tools/protein).

## How to split it across the day

Total daily protein matters most, but distribution helps. Aim for **3–4 meals of around 0.4 g/kg each** (roughly 30–40 g for most people). This keeps muscle-building signalling topped up through the day. A protein source at each meal — plus a snack if needed — makes the total easy to hit.

## Best protein sources

| Source | Notes |
| --- | --- |
| Lean meat, poultry, fish | High quality, very satiating |
| Eggs & dairy (incl. Greek yoghurt) | Convenient, complete protein |
| Legumes, tofu, tempeh | Strong plant options (combine for completeness) |
| Whey or plant protein powder | Easy way to top up the daily total |

## Where protein fits in the bigger picture

Protein sets the foundation, but muscle also needs progressive training and enough total energy. Pair your protein target with the [macro calculator](/tools/macro) for carbs and fat, the [calorie target calculator](/tools/calorie-target) for your overall intake, and the training principles in our [how to build muscle](/learn/how-to-build-muscle) guide. Our [muscle-growth programme](/programmes/muscle-growth) ties it all together and adjusts as your data changes.

## FAQ

### How much protein per day to build muscle?

About 1.6–2.2 g per kg of bodyweight per day. For an 80 kg person that's roughly 130–175 g. Use our protein calculator for your number.

### Can you eat too much protein?

For healthy people, intakes in this range are safe. Much higher offers little extra muscle benefit and crowds out other nutrients.

### Does protein timing matter?

Total daily protein matters most. Spreading it across 3–4 meals is a sensible, well-supported approach, but you don't need to obsess over a post-workout 'window'.
