Protein and Muscle Growth: The Ultimate Guide

# Protein and Muscle Growth: The Ultimate Guide

Protein is the building block of muscle. But how much do you actually need? Which sources are best? Let's get precise.

How Much Protein?

The research is clearer than supplement marketing:

Optimal range: 1.6-2.2g per kg bodyweight daily

That's 110-150g for an 80kg lifter. Beyond 2.2g/kg, you hit diminishing returns.

Quick Calculator

| Bodyweight | Minimum | Optimal |

|------------|---------|---------|

| 60kg | 96g | 120g |

| 70kg | 112g | 140g |

| 80kg | 128g | 160g |

| 90kg | 144g | 180g |

Protein Timing: Does It Matter?

The "anabolic window" — eat protein within 30 minutes of training or miss your gains — is mostly myth.

What actually matters:

• Total daily protein intake

Even distribution (3-4 meals)

Protein synthesis peaks 3-5 hours after eating. Spread intake across the day to keep muscle building.

Best Protein Sources

Animal Sources (Complete Proteins)

Chicken breast: 31g per 100g

Eggs: 6g each (whole)

Greek yogurt: 10g per 100g

Beef: 26g per 100g

Fish: 20-25g per 100g

Whey protein: 24g per scoop

Plant Sources

Lentils: 9g per 100g cooked

Tofu: 8g per 100g

Tempeh: 19g per 100g

Seitan: 25g per 100g

Pro tip: Combine plant sources to hit complete amino profile (rice + beans = complete protein).

Whey vs Whole Food

Whey isn't better than chicken. It's more convenient.

Whey advantages:

Fast absorption (good post-workout)

Easy to measure

Low prep

Whole food advantages:

More filling

Slower absorption (sustained amino release)

More nutrients

Use both. Whey for convenience, whole food for primary intake.

Common Questions

Can you build muscle on a vegan diet?

Yes. Combine sources, hit total intake, and train hard.

Is too much protein bad for kidneys?

Only if you have pre-existing kidney issues. For healthy lifters, excess protein is excreted.

Should you eat protein before bed?

Casein (slow-digesting) is popular but total daily intake matters more.

The Bottom Line

1. Eat 1.6-2.2g protein per kg bodyweight

2. Spread across 3-4 meals

3. Prioritize whole foods

4. Use whey for convenience

5. Don't stress timing
