Protein Calculator
Calculate how much protein you need daily based on your body weight and fitness goals.
Protein is essential for building and maintaining lean muscle, supporting metabolic health, and promoting recovery. Whether you’re an athlete, trying to lose fat, or simply living an active lifestyle, getting the right amount of protein is key to performance and well-being.
Why Is Protein Important?
Protein plays a crucial role in:
- Muscle growth and repair
- Enzyme and hormone production
- Immune system support
- Satiety and appetite control
Unlike carbohydrates and fats, your body doesn’t store protein — so you need to consume it consistently each day.
How the Protein Calculator Works
This calculator uses a simple formula:
Daily Protein Intake (grams) = Body Weight (kg) × Protein Ratio
You choose the protein ratio based on your activity level and goals. The calculator then provides your recommended daily protein intake in grams.
Recommended Protein Ratios
Here are general protein intake guidelines based on your lifestyle:
| Goal | Protein Ratio (g/kg) |
|---|---|
| Sedentary lifestyle | 0.8 – 1.0 g/kg |
| Active (light exercise) | 1.2 – 1.6 g/kg |
| Muscle maintenance | 1.6 – 2.0 g/kg |
| Muscle gain / strength training | 2.0 – 2.4 g/kg |
| Fat loss / body recomposition | 2.2 – 2.6 g/kg |
You can input a custom ratio that fits your needs.
Example
A person weighing 70 kg looking to gain muscle may use a ratio of 2.2 g/kg:
70 kg × 2.2 = 154 grams of protein per day
This gives a clear target to structure your meals around.
Tips for Hitting Your Protein Goal
- Include protein in every meal (meat, eggs, dairy, legumes, tofu).
- Use high-protein snacks like Greek yogurt, protein bars, or shakes.
- Space intake evenly across the day to support muscle protein synthesis.
- Track your intake using a food diary or nutrition app.
