Introduction
Wondering how much protein per day you actually need? Or asking yourself “how much protein should I eat a day to build muscle?” You’re not alone.
Getting your protein intake right can make a real difference when working towards your fitness goals—whether that’s building muscle, staying active, or simply supporting your daily nutrition.
In this guide, we’ll break down how much protein do I need, how to calculate protein intake, and how to make hitting your target simple and realistic.
The importance of protein
Protein is an essential macronutrient made up of amino acids—the building blocks your body uses every day.
It contributes to:
- Growth in muscle mass
- Maintenance of muscle mass
- Maintenance of normal bones
Since your body doesn’t store protein the same way it does fats or carbohydrates, it’s important to include protein regularly in your daily diet.
Foods like meat, fish, dairy, legumes, nuts, and seeds all provide protein—making it easy to find options that fit your lifestyle.
How much protein per day do you really need?
So, how much protein should I have a day? The answer depends on your body weight, activity level, and goals.
- General guideline
0.8g per kg body weight = baseline recommendation
- Active lifestyle or fitness goals
If you're training regularly or aiming for muscle growth:
1.6 – 2.2g per kg body weight
This is where many people start asking:
- How many grams of protein per day do I need?
- How much protein to build muscle?
Example
If you weigh 70kg:
- Minimum: 56g protein/day
- Active goal: 112–154g protein/day
If you’re unsure how to calculate your needs, using a protein calculator or speaking to a professional can help you personalise your intake.
How to calculate protein intake (based on kg)
Understanding how to calculate protein intake is simple:
👉 Multiply your body weight (kg) by your target intake:
- Light activity: weight × 0.8
- Active: weight × 1.6–2.2
This helps answer common questions like:
- How much protein should I eat a day?
- How much protein do I need to build muscle?
Keep in mind: consistency matters more than perfection.
