To build muscle effectively, aim for 1.6–2.2 grams of protein per kilogram of body weight daily if you're strength training consistently—this range maximizes muscle protein synthesis based on multiple expert sources. For example, a 70kg (154lb) person should target 112–154g, spread across 3–5 meals for optimal absorption.

Why This Amount?

The standard RDA of 0.8g/kg is just for basic health, not muscle growth; active lifters need more to repair and build tissue post-workout. Studies show gains plateau beyond 1.6g/kg, but up to 2.2g/kg supports intense training without excess waste. Imagine your muscles as construction sites—protein provides the bricks, but you don't need a truckload if the crew (your workouts) isn't working overtime.

Quick Calculation Table

Use your body weight to estimate (convert lbs to kg by dividing by 2.2):

Body Weight (kg)| Daily Protein (g) for Muscle Gain
---|---
60| 96–132
70| 112–154
80| 128–176
90| 144–198

Pro Tip: If overweight, base it on ideal body weight or height (e.g., 50g base + 7g per inch over 5ft).

Best Protein Sources

  • Animal: Chicken (30g/100g), eggs (6g each), salmon (25g/100g)—complete amino acids for fast repair.
  • Plant: Lentils (9g/100g cooked), tofu (15g/100g), quinoa (14g/100g)—combine for full profile if vegan.

High-protein foods like Greek yogurt or whey shakes make hitting targets easy without force-feeding.

Timing and Common Pitfalls

Eat 20–40g per meal every 3–4 hours; post-workout windows help but aren't magic. Don't exceed 2.2g/kg long-term—extra just becomes fuel or fat, risking kidney strain if unfit. Trending in 2025 forums: Pair with carbs for better uptake, per recent StrengthLog updates.

TL;DR Bottom Line

Target 1.6–2.2g/kg body weight (e.g., 120–160g for average adult) from whole foods, adjusted for your training. Track via apps, lift heavy, and consistency beats perfection. Information gathered from public forums or data available on the internet and portrayed here.
